Methyltransferase TaSAMT1 mediates wheat freezing tolerance by integrating brassinosteroid and salicylic acid signaling
Plant Science Research WeeklyTemperature extremes, such as cold stress, severely affect wheat (Triticum aestivum) productivity and quality by impairing its vegetative and reproductive growth. Several phytohormones have roles in cold stress, such as brassinosteroids (BRs) and salicylic acid (SA). However, how BR interacts with SA…
RAF-like protein kinases mediate a deeply conserved, rapid auxin response
Plant Science Research WeeklyThe definition of a phytohormone has not always been clear, though most plant biologists agree that phytohormones can be defined as endogenous molecules capable of triggering signaling cascades and associated responses by binding to specific receptors. They have been extensively studied in flowering…
The main oxidative inactivation pathway of the plant hormone auxin (Nature Comms.)
Plant Science Research WeeklyAuxin is a key hormone in almost all stages of the plant development and its main natural form is indole-3-acetic acid (IAA). In Arabidopsis, several gene families are involved in auxin homeostasis. In this work, Hayashi et al. focus on the roles of DIOXYGENASE FOR AUXIN OXIDATION 1 (DAO1) which converts…
A "simple” plant that’s not so basic: 13 receptors perceive SL, KL, and more in moss
