Plant genetics

Definition

Plant genetics deals with heredity in plants, specifically mechanisms of hereditary transmission and variation of inherited characteristics. Plant genetics differs from animal genetics in a number of ways: somatic mutations can contribute to the germ line more easily as flowers develop at the end of branches composed of somatic cells; polyploidy is more common; and plants additionally contain chloroplastic DNA.

    Analysis of a large bread-wheat genomic data set through a quantitative genetic framework designed to study the genetic basis of heterosis shows that hybrids outperform midparents in grain yield by 10%. Genome-wide prediction and association mapping indicate that epistasis plays a significant role in heterosis of grain yield in wheat.

    Barnyardgrass is a problematic agricultural weed. Here, via genomic analysis, Guo et al. identify genes potentially underlying its success, including a gene cluster activated in response to co-cultivation with rice that leads to synthesis of the allelochemical DIMBOA.

    The VRS genes of barley control the fertility of the lateral spikelets on the barley inflorescence. Here, Bull et al. show that VRS3 encodes a putative Jumonji C-type histone demethylase that regulates expression of other VRS genes, and genes involved in stress, hormone and sugar metabolism.

    The assembly of the durian genome provides insights into the unique flavor profile of this tropical fruit. Transcriptome and metabolome analyses show that methionine γ-lyase is upregulated and that volatile sulfur compounds are produced during ripening.

    Heterosis can rapidly boost yield in crop species but development of hybrid-breeding systems for bread wheat remains a challenge. Here, Tucker et al. describe the molecular identification of the wheat Ms1 gene and discuss its potential for large-scale hybrid seed production in wheat.
