    ABSTRACT: Nucleotide-binding site (NBS) disease resistance genes play a crucial role in plant defense responses against pathogens and insect pests. Many NBS-encoding genes have been detected in Lotus japonicus, an important forage crop in many parts of the world. However, most NBS genes that have been identified so far in L. japonicus are only partial sequences. We identify 45 full-length NBS-encoding genes in the L. japonicus genome. We analyzed gene duplications, motifs and the gene phylogeny to further understand the NBS gene family. We found that gene duplication events rarely occur in L. japonicus NBS-encoding (LjNBS) genes, suggesting that most LjNBS genes are lost after gene duplication events. In addition, LjNBS gene suffered in selection pressure and codon usage bias was performed. We tested for purifying selection (specifically, in the CC-NBS-LRR and TIR-NBS-LRR groups) and found strong purifying selection in the TIR-domain-containing sequences, indicating that the CC-NBS-LRR group is more likely to undergo expansion than the TIR-NBS-LRR group. Moreover, our results showed that both selection and mutation contributed to LjNBS codon usage bias, but mutational bias is the major influence on codon usage.

    ABSTRACT: The aim of this study was to evaluate the reliability of flow cytometry analysis and the use of this technique to differentiate species and varieties of sugarcane (Saccharum spp) according to their relative DNA content. We analyzed 16 varieties and three species belonging to this genus. To determine a reliable protocol, we evaluated three extraction buffers (LB01, Marie, and Tris·MgCl2 ), the presence and absence of RNase, six doses of propidium iodide (10, 15, 20, 25, and 30 µg), four periods of exposure to propidium iodide (0, 5, 10, and 20 min), and seven external reference standards (peas, beans, corn, radish, rye, soybean, and tomato) with reference to the coefficient of variation and the DNA content. For statistical analyses, we used the programs Sisvar® and Xlstat®. We recommend using the Marie extraction buffer and at least 15 µg propidium iodide. The samples should not be analyzed immediately after the addition of propidium iodide. The use of RNase is optional, and tomato should be used as an external reference standard. The results show that sugarcane has a variable genome size (8.42 to 12.12 pg/2C) and the individuals analyzed could be separated into four groups according to their DNA content with relative equality in the

    ABSTRACT: Pseudevernia furfuracea L. (Zopf), Peltigera praetextata (Flörke ex Sommerf.) Zopf, Lobaria pulmonaria (L.) Hoffm., and Usnea longissima Ach. lichen species were used as bioindicators to assess the genotoxicity of air pollutants. In the present study, we examined significant environmetal pollutants and investigate how changes may lead to damage in DNA structure using RAPD markers. In the study area (Erzurum, Turkey), poor-quality lignite, which generates a large amount of sulfur dioxide, nitrogen oxides, and particle matter, is used for domestic heating, and vehicles also contribute to air pollution. Control lichen samples were collected far from large urban and industrial settlements and transplanted to four polluted sites for 4, 8, or 12 months. The total soluble protein content of the examined four lichen species did not significantly change with exposure time (P < 0.05). The four lichen samples exposed to the pollutants for 8 months had the highest ratio of DNA changes. The ratio of band differencesin P. praetextata was higher than that in the other three lichen species, possibly because it has broad leaves that accumulated more pollutants. The average incidences of polymorphism were 64.14, 54.58, 65.76, and 43.06% for P. furfuracea, P. praetextata, L. pulmonaria, and U. longissima, respectively. The genomic template stability (GTS) significantly decreased following exposure to pollutants. GTS ratios revealed that the highest value (98.36%) belonged to U. longissima samples from Site 1 (10 m) after 4 months of exposure, and the lowest values belonged to P. praetextata (73.58%) from Site 3 (100 m) after 8 months of exposure. Based on our findings, we recommend the use of P. praetextata as an indicator of genotoxicity.

    ABSTRACT: Shoot branching, i.e., the timing and position of shoot growth, determines to a large extend the pattern of plant architecture, and is the result of the integration of a plant’s genetic background and environmental cues. Many genes that are involved in the formation and outgrowth of axillary buds have been cloned, but the exact mechanism is still unclear. Branching pattern is an important agronomic trait in many crops, including cotton. In the present study, we cloned four genes from cotton, and designated them as GhLOF1/2/3/4. Sequence analysis revealed that all four genes shared conserved protein domains with LATERAL ORGAN FUSION (LOF) from Arabidopsis and TRIFOLIATE (Tf) from tomato. Phylogenetic analysis revealed that GhLOF3 and GhLOF4 were close to Tf because of their similar expression patterns, whereas GhLOF1 and GhLOF2 were differentially expressed.
