Identification and characterization of CYC2-like genes related to floral symmetric development in Tagetes erecta (Asteraceae).

Scientists discovered and cloned seven TeCYC2 genes in marigold, altering the symmetry of Arabidopsis flowers when expressed, revealing their interaction and potential applications in molecular breeding for varied flower forms.

Dose effects of restorer gene modulate pollen fertility in cotton CMS-D2 restorer lines via auxin signaling and flavonoid biosynthesis.

The study examined gene alleles in CMS-D2 cotton and found that the homozygous RfRf genotype had higher fertility than the heterozygous Rfrf genotype. Key genes and metabolites were identified, and over-activation of auxin signaling was found to inhibit pollen development. These findings shed light on the regulation of pollen fertility in CMS-D2 cotton.
