    ABSTRACT: * Craterostigma plantagineum tolerates extreme desiccation. Leaves of this plant shrink and extensively fold during dehydration and expand again during rehydration, preserving their structural integrity. Genes were analysed that may participate in the reversible folding mechanism. * Analysis of transcripts abundantly expressed in desiccated leaves identified a gene putatively coding for an apoplastic glycine-rich protein (CpGRP1). We studied the expression, regulation and subcellular localization of CpGRP1 and its ability to interact with a cell wall-associated protein kinase (CpWAK1) to understand the role of CpGRP1 in the cell wall during dehydration. * The CpGRP1 protein accumulates in the apoplast of desiccated leaves. Analysis of the promoter revealed that the gene expression is mainly regulated at the transcriptional level, is independent of abscisic acid (ABA) and involves a drought-responsive cis-element (DRE). CpGRP1 interacts with CpWAK1 which is down-regulated in response to dehydration. * Our data suggest a role of the CpGRP1–CpWAK1 complex in dehydration-induced morphological changes in the cell wall during dehydration in C. plantagineum. Cell wall pectins and dehydration-induced pectin modifications are predicted to be involved in the activity of the CpGRP1–CpWAK1 complex.

    ABSTRACT: Extending the durability of plant resistance genes towards fungal pathogens is a major challenge. We identified and investigated the relationship between two avirulence genes of Leptosphaeria maculans, AvrLm3 and AvrLm4-7. When an isolate possesses both genes, the Rlm3-mediated resistance of oilseed rape (Brassica napus) is not expressed due to the presence of AvrLm4-7 but virulent isolates toward Rlm7 recover the AvrLm3 phenotype. Combining genetic and genomic approaches (genetic mapping, RNA-seq, BAC (bacterial artificial chromosome) clone sequencing and de novo assembly) we cloned AvrLm3, a telomeric avirulence gene of L. maculans. AvrLm3 is located in a gap of the L. maculans reference genome assembly, is surrounded by repeated elements, encodes for a small secreted cysteine-rich protein and is highly expressed at early infection stages. Complementation and silencing assays validated the masking effect of AvrLm4-7 on AvrLm3 recognition by Rlm3 and we showed that the presence of AvrLm4-7 does not impede AvrLm3 expression in planta. Y2H assays suggest the absence of physical interaction between the two avirulence proteins. This unusual interaction is the basis for field experiments aiming to evaluate strategies that increase Rlm7 durability.

    ABSTRACT: The number of leaves and their distributions on plants are critical factors determining plant architecture in maize (Zea mays), and leaf number is frequently used as a measure of flowering time, a trait that is key to local environmental adaptation. Here, using a large set of 866 maize-teosinte BC2 S3 recombinant inbred lines genotyped by using 19 838 single nucleotide polymorphism markers, we conducted a comprehensive genetic dissection to assess the genetic architecture of leaf number and its genetic relationship to flowering time. We demonstrated that the two components of total leaf number, the number of leaves above (LA) and below (LB) the primary ear, were under relatively independent genetic control and might be subject to differential directional selection during maize domestication and improvement. Furthermore, we revealed that flowering time and leaf number are commonly regulated at a moderate level. The pleiotropy of the genes ZCN8, dlf1 and ZmCCT on leaf number and flowering time were validated by near-isogenic line analysis. Through fine mapping, qLA1-1, a major-effect locus that specifically affects LA, was delimited to a region with severe recombination suppression derived from teosinte. This study provides important insights into the genetic basis of traits affecting plant architecture and adaptation. The genetic independence of LA from LB enables the optimization of leaf number for ideal plant architecture breeding in maize.

    ABSTRACT: The ‘apparently’ simple genomes of many angiosperms mask complex evolutionary histories. The reference genome sequence for cotton (Gossypium spp.) revealed a ploidy change of a complexity unprecedented to date, indeed that could not be distinguished as to its exact dosage. Herein, by developing several comparative, computational and statistical approaches, we revealed a 5× multiplication in the cotton lineage of an ancestral genome common to cotton and cacao, and proposed evolutionary models to show how such a decaploid ancestor formed. The c. 70% gene loss necessary to bring the ancestral decaploid to its current gene count appears to fit an approximate geometrical model; that is, although many genes may be lost by single-gene deletion events, some may be lost in groups of consecutive genes. Gene loss following cotton decaploidy has largely just reduced gene copy numbers of some homologous groups. We designed a novel approach to deconvolute layers of chromosome homology, providing definitive information on gene orthology and paralogy across broad evolutionary distances, both of fundamental value and serving as an important platform to support further studies in and beyond cotton and genomics communities.
