The CONSTANS-LIKE (COL) gene is key to plant photoperiod signalling. Tetrastigma hemsleyanum is a medicinal plant that grows only in China. Its root tuber extracts have good effect on the clinical treatment of tumours. The formation and development of its tuberous roots are related to photoperiod. In this study, the expression profiles of COL genes in T. hemsleyanum leaf under different photoperiod conditions was analysed and used to analyse whether COL genes have a role in T. hemsleyanum perception of photoperiod signalling.

Abscisic acid (ABA) is a key player in how plants adapt to their environment, from growth to coping with stress. In this study, we identified the PYL genes in potatoes (Solanum tuberosum), crucial for ABA signalling pathways, yet poorly understood in potato. We uncover 17 PYL genes in potatoes, revealing their diverse roles in stress response and growth regulation. These findings shed light on potential role of PYL genes in mitigating the multiple stresses.
