Flowering, a pivotal plant lifecycle event, is intricately regulated by environmental and endogenous signals via genetic and epigenetic mechanisms. Photoperiod is a crucial environmental cue that induces flowering by activating integrators through genetic and epigenetic pathways. However, the specific role of DNA methylation, a conserved epigenetic marker, in photoperiodic flowering remains unclear.

Tartary buckwheat (Fagopyrum tataricum), a functional grain known for its medicinal and nutritional properties, has garnered significant attention due to its high flavonoid content and unique health benefits. Heat stress during the flowering stage can lead to sterility in Tartary buckwheat, resulting in reduced yields. This study investigates the effects of a treatment (30/27 °C for 7 days) on flower development, fertility, stress physiology, and gene expression in Tartary buckwheat, while also validating the efficacy of hormone treatments in alleviating the negative effects of heat stress.

Monocarpic plants flower only once and then produce seeds. Many monocarpic plants require a cold treatment known as vernalization before they flower. This requirement delays flowering until the plant senses warm temperatures in the spring.

Photoperiodic regulation of flowering time plays a critical role in plant reproductive success and crop yield. In Arabidopsis thaliana, the expression of the CONSTANS (CO) gene is closely regulated by day length and is modulated by both environmental and endogenous cues for precise control over flowering. Our findings reveal that the phytohormone brassinosteroid (BR) pathway represses flowering by inhibiting the expression of both CO and Flowering Locus T (FT).
