    ABSTRACT: Rj2 is a TIR-NBS-LRR-type resistance gene in soybean (Glycine max) that restricts root nodule symbiosis with a group of Bradyrhizobium japonicum strains including USDA122. Rj2 generates two distinct transcript variants in its expression profile through alternative splicing. Alternative splicing of Rj2 is caused by the retention of the 86-bp intron 4. Inclusion of intron 4 in mature mRNA introduces an in-frame stop codon; as such, the alternative transcript is predicted to encode a truncated protein consisting of the entire portion of the TIR, NBS, and LRR domains but missing the C-terminal domain of the full-length Rj2 protein encoded by the regular transcript. Since alternative splicing has been shown to be essential for full activity of several plant R genes, we attempted to test whether the alternative splicing is required for Rj2-mediated nodulation restriction. Here we demonstrated that the Rj2-mediated nodulation restriction does not require the combined presence of the regular and alternative transcripts, and the expression of the regular transcript alone is sufficient to confer nodulation restriction.

    ABSTRACT: Lilium longiflorum (Easter lily) vegetative propagation occurs through production of underground bulbs containing an apical and an axillary meristems. In addition, sexual reproduction is achieved by flowering of elongated shoots above the bulb. It is generally accepted that L. longiflorum has an obligatory requirement for vernalization and that long day (LD) regime hastens flowering. However, the effect of bulb size and origin, with respect to axillary or apical meristem on flowering, as well as the interactions between these meristems are largely unknown. The aim of this study was to explore the effect of bulb size, vernalization and photoperiod on L. longiflorum flowering. To this end, we applied vernalization and photoperiod treatments on the different bulb sizes and used a system of constant ambient temperature of 25°C, above vernalization spectrum, to avoid cold-dependent floral induction during plant growth. Vernalization and LD hasten flowering in all bulbs. Large, non-vernalized bulbs invariably remained at a vegetative stage. However, small non-vernalized bulbs flowered under LD conditions. These results demonstrate for the first time that cold exposure is not an obligatory requisite for L. longiflorum flowering, and that an alternative flowering pathway can by-pass vernalization in small bulbs. We suggest that apical dominance interactions determine the distinct flowering pathways of the apical and the axillary meristems. Similar floral induction is achieved in propagation bulblets from scaling. These innovative findings in the field of geophyte floral induction represent valuable applicative knowledge for lily production. This article is protected by copyright. All rights reserved.

    ABSTRACT: Information about the photosynthetic process and their limitants is essential in order to predict both the capacity of these species to adapt to conditions associated with climate change and the likely changes in plant communities. Considering that high mountain species are specially sensitive, three species representative of subalpine forests of the Central Catalan Pyrenees: mountain pine (Pinus uncinata Mill.), birch (Betula pendula Roth) and rhododendron (Rhododendron ferrugineum L.) were studied under circumstances associated with climate change such as low precipitation regimes, elevated atmospheric [CO2 ] and high solar irradiation intensity incident at Earth's surface, in order to detect their photosynthetic limitants. Short-term high [CO2 ] conditions gave rise to increased photosynthesis rates (A) and water use efficiency (WUE), especially in birch and mountain pine, whereas stomatal conductance (gs ) was not altered in either of these species. Birch presented photosynthesis limitation by stomatal closure related to low rainfall, which in turn induced photoinhibition and earlier foliar senescence. Rhododendron was especially affected by high irradiance levels, showing early photosynthesis saturation at low values, the highest chlorophyll content, lowest gas-exchange rates and the lowest levels of photoprotection. Mountain pine showed highest A, photosynthetic capacity (Amax ) and light saturated rates of net CO2 assimilation (Asat ) which were maintained under decreasing precipitations. Furthermore, maximum quantum yield (Fv /Fm ), thermal energy dissipation, PRI and SIPI radiometric index, and ascorbate content indicated improved photoprotection with respect to the other species. However, values of the maximum velocity of carboxylation of RuBisco (Vc max ) indicated that N availability would be the main photosynthetic limitant in this species.

    ABSTRACT: Phase II of seed imbibition is a critical process during seed priming. To identify genes involved in rice seed priming, the altered proteins between the dry and imbibed (24 h) seeds were compared using a two-dimensional gel electrophoresis system in this stuy. Ten significantly changed proteins (fold change ≥ 2.0-fold and P<0.01) were successfully identified, which could be categorized as carbohydrate and protein biosynthesis and metabolism related-, signaling related-, storage and stress related- proteins. A meta-analysis indicated that the highest expression of the identified genes was at the milk and dough stages and in the endosperm tissue. Quantitative real-time PCR analysis showed that there was significant variation of gene expression (except FAD dependent oxidoreductase) in embryos during seed priming (0 to 48 h). The expression of genes associated with stress appeared at the early imbibition stage, while those associated with carbohydrate metabolism, protein synthesis and signal increased at the late imbibition stage. Three identified proteins (glucose-1-phosphate adenylyltransferase large subunit, aminotransferase and prolamin precursor) had the similar transcript and protein expression patterns in embryos. Based on phenotype and gene expression, the optimal stop time for seed priming is 24 h when these three genes have relatively low expression followed by a significant induction during imbibition in embryos. These three genes are ideal candidate biomarkers for rice seed priming. This article is protected by copyright. All rights reserved.

    ABSTRACT: Ecological disturbances caused by roadways have previously been reported, but traffic speed has not been addressed. We investigate effects of traffic speed on pollination of Centratherum punctatum (Asteraceae) along an Amazonian highway roadside. We hypothesized that frequency of flower visitors, duration of single visits, and pollen deposition on stigmas will vary negatively as traffic speed increases. After measuring vehicle velocities, we classified three road sections as low-, mid- and high-velocity traffic. The main pollinator bee, Augochlora sp., visited C. punctatum inflorescences with decreasing frequency from low- to high-velocity roadside sections, whereas the nectar thief butterflies did the opposite. Duration of single visits by bees and butterflies was shorter, and arrival of pollen on C. punctatum stigmas was lower, in high- than in low-velocity roadside. Air turbulence due to passing vehicles increases with velocity and disturbed the flower visitors. Overall results support that traffic velocity negatively affects foraging of flower visitors and the pollination of C. punctatum on roadsides. This article is protected by copyright.

    ABSTRACT: Hydroxy methylglutaryl-coenzyme-A synthase (HMGS) is a rate-limiting enzyme in the cytoplasmic isoprenoid biosynthesis pathway leading to natural rubber production in Hevea brasiliensis. Analysis of the structural variants of this gene is imperative to understand their functional significance in rubber biosynthesis so that they can be properly utilized for the ongoing crop improvement programmes in Hevea. We report here the allele richness and diversity of HMGS gene prevailing in selected popular rubber clones. Haplotypes consisting of SNPs from the coding and non-coding regions with high degree of heterozygosity were identified. Segregation and linkage disequilibrium analysis confirmed that recombination is the major contributor towards the generation of allelic diversity rather than point mutations. The evolutionarily conserved nature of some SNPs was identified by comparative DNA sequence analysis of HMGS orthologs from diverse taxon, expounding the molecular evolution of rubber biosynthesis genes in general. In silico 3D structural studies highlighting the structural positioning of non synonymous SNPs belonging to different HMGS haplotypes revealed that the ligand binding site on the enzyme remains impervious to the sequence structure variations. Alternatively, gene expression results indicated the possibility of association between specific haplotypes and HMGS expression in Hevea clones which may have downstream impact up to the level of rubber production. Moreover, haplotype diversity of HMGS gene and their putative association with gene expression can be the base for further genetic association studies in rubber. Besides, the data also take cognizance of the role of SNPs in the evolution of candidate genes coding for functional trait in plants. This article is protected by copyright. All rights reserved.

    ABSTRACT: Bamboos are one of the fastest growing plants on Earth, and are widely considered to have high ability to capture and sequester atmospheric carbon, and consequently to mitigate climate change. We tested this hypothesis by measuring carbon dioxide (CO2) emissions from bamboo culms and comparing with their biomass sequestration potential. We analyzed diurnal effluxes from Bambusa vulgaris culm surface and gas mixtures inside hollow sections of various bamboos by gas chromatography. Corresponding variations in gas pressure inside the bamboo section and culm surface temperature were measured. SEM micrographs of rhizome and bud portions of bamboo culms were also recorded. We found very high CO2 effluxes from culm surface, nodes and buds of bamboos. Positive gas pressure and very high concentration of CO2 were observed inside hollow sections of bamboos. The CO2 effluxes observed from bamboos is very high compared to their carbon sequestration potential. Our measurements suggest that bamboos are net emitters of CO2 during their lifespan.

    ABSTRACT: Zygotic embryos from recalcitrant seeds are sensitive to desiccation. In spite of their sensitivity, rapid partial dehydration is necessary for their successful cryopreservation. However, dehydration to water contents (WCs) that preclude lethal ice crystal formation during cooling and rewarming generally leads to desiccation damage. This study investigated the effects of rapid dehydration on selected stress biomarkers (electrolyte leakage, respiratory competence, rate of protein synthesis, superoxide production, lipid peroxidation, antioxidant activity and degree of cellular vacuolation) in zygotic embryos of four recalcitrant-seeded species. Most biomarkers indicated differences in the levels of stress/damage incurred by embryos dried to WCs < and >0.4 g g−1, within species; however, these changes were often unrelated to viability and % water loss when data for the four species were pooled for regression analyses. Dehydration-induced electrolyte leakage was, however, positively related with % water loss, while biomarkers of cellular vacuolation were positively related with both % water loss and viability. This suggests that electrolyte leakage and degree of cellular vacuolation can be used to quantify dehydration-induced stress/damage. Biomarkers such as superoxide production, whilst useful in establishing the nature of the dehydration stress incurred may not be able to distinguish the effects of different WCs/drying times. Irrespective of which biomarker is used, the data suggest that understanding differences in desiccation sensitivity across recalcitrant-seeded species will remain a challenge unless these biomarkers are related to a generic desiccation stress index that integrates the effects of % water loss and drying time.

    ABSTRACT: Karyotype data within a phylogenetic framework and molecular dating were used to examine chromosome evolution in Nierembergia and to infer how geological or climatic processes have influenced in the diversification of this solanaceous genus native to South America and Mexico. Despite the numerous studies comparing karyotype features across species, including the use of molecular phylogenies, to date relatively few studies have used formal comparative methods to elucidate chromosomal evolution, especially to reconstruct the whole ancestral karyotypes. Here, we mapped on the Nierembergia phylogeny one complete set of chromosomal data obtained by conventional staining, AgNOR-, C- and fluorescent chromosome banding, and fluorescent in situ hybridization. In addition, we used a Bayesian molecular relaxed clock to estimate divergence times between species. Nierembergia showed two major divergent clades: a mountainous species group with symmetrical karyotypes, large chromosomes, only one nucleolar organizing region (NOR), and without centromeric heterochromatin, and a lowland species group with asymmetrical karyotypes, small chromosomes, two chromosomes pairs with NORs and centromeric heterochromatin bands. Molecular dating on the DNA phylogeny revealed that both groups diverged during Late Miocene, when Atlantic marine ingressions called the "Paranense Sea" probably forced the ancestors of these species to find refuge in unflooded areas for about 2 M years. This split agrees with an increased asymmetry and heterochromatin amount, and decrease in karyotype length and chromosome size. Thus, when the two Nierembergia ancestral lineages were isolated, major divergences occurred in chromosomal evolution, and then each linage underwent speciation separately, with relatively minor changes in chromosomal characteristics.
