Grain size and weight are closely related traits determining yield in rice(Oryza sativa L.).Since indica and japonica rice varieties differ significantly in multiple traits,a high-generation recombinant inbred line(RIL)population derived from the crossing LH9(indica)and RPY(japonica)was used to map grainrelated traits in six *** of the quantitative trait loci(QTL)for thousand-grain weight showed that combinations of multiple QTL significantly increased the phenotypic effect.A novel gene named GSW3.1 controlling grain size and weight was discovered using the major QTL for the colocalization of grain width and thousand-grain weight on chromosome *** editing revealed that GSW3.1(LOC_Os03g16850)was pleiotropic,positively regulating grain size and weight while affecting several other agronomic *** analysis indicated that some traits,including grain width and weight,were highly correlated with indica-japonica differentiation.

Guardians of the fragrance:Uncovering the genetics behind citrus oil glands

The colorful,nutrient-rich peels of citrus fruits have long been valued for their tangy flavors and aromatic *** oils are produced and stored in special secretory structures called oil glands,which are prevalent across citrus varieties(Knight et al.,2001).Oil glands serve as"reservoirs"for diverse metabolites such as terpenes and flavonoids that give citrus fruits their characteristic aroma(Mahato et al.,2019;Voo et al.,2012;Xian et al.,2022).Many of these compounds also act as chemical defenses against pest and pathogens(Fisher and Phillips,2008).
