De novo evolution of genes was used as an important approach in the rice breeding program. The identification of the novel genes in the rice genome regulates economic traits such as grain size, weight, and others linked to grain yield or quality. Specific novel genes, also called orphan genes...
Altogether, the study provides insights on characteristics of ARF/ARL genes in rice and foxtail millet, which could be deployed for further functional analysis to extrapolate their precise roles in abiotic stress responses. ADP-ribosylation factors (ARFs) belong to Ras superfamily of small GTP-...
Evolutionary divergence between homologous X–Y chromosome genes shapes sex-biased biology Based on co-expression fingerprint analysis between homologous genes in the X and Y chromosomes (gametolog pairs) across >40 human tissues, the authors suggest that X and Y gametologs have diverged in functio...
owing to sex-specific selection that arises from different reproductive strategies of the sexes. The pace-of-life syndrome (POLS) hypothesis predicts that most variation in such traits among individuals, populations, and species falls along a slow-fast pace-of-life continuum. As a result of ...
Evolutionary rates are not constant across the human genome but genes in close proximity have been shown to experience similar levels of divergence and selection. The higher-order organisation of chromosomes has often been invoked to explain such phenomena but previously there has been insufficient data...
Numerous studies have focused on DELLA genes in vascular plants (Table 1). The DELLA family has expanded in vascular plants owing to gene duplication. DELLAs are present mainly in the form of polygenes, with a few in the form of single genes in rice, wheat, and cotton. Large differences ...
Hydrophobins are small secreted cysteine-rich proteins that play diverse roles during different phases of fungal life cycle. In basidiomycetes, hydrophobin-encoding genes often form large multigene families with up to 40 members. The evolutionary forces driving hydrophobin gene expansion and diversification...
by using a comparative genomic approach and phylogenetic analysis, we compared C4 genes and their non-C4 isoforms in sorghum, maize and rice. The aims of this study are to investigate: the role of gene duplication in the evolution of C4 enzyme genes; the role of adaptive evolution in C4 pa...
Mechanisms confer to the enhanced cold tolerance in japonica rice have not been fully elucidated. Here, the authors report a homeodomain-leucine zipper (HD-Zip) I transcription factor encode gene CTB5 is responsible for japonica rice cold tolerance by interacting with genes in gibberellin and abscis...
We survey 141 sequenced plant genomes to elucidate consequences of gene and genome duplication, processes central to the evolution of biodiversity. We develop a pipeline namedDupGen_finderto identify different modes of gene duplication in plants. Genes derived from whole-genome, tandem, proximal, trans...
