The model not only predicted outcomes under various genetic and hormonal conditions, but also incorporated new data on a previously unknown region of the #PIN1 auxin transporter that mediates its response to #strigolactone, offering fresh molecular insight into hormonal control of bud growth."

🌱From Bud to Branch🌱 New model reveals how local & systemic signals combine to regulate shoot branching. "...by modulating #auxin transport, local #BRC1 expression in each bud could contribute to the systemic control of branching." @zoenahas.bsky.social 🔗 dx.plos.org/10.1371/jour... @plosbiology.org
Axillary buds are located at the base of each leaf. Initially dormant, each can grow into a branch. To study how branching is regulated by local signalling within each bud and by systemic signalling from other buds, we used stem sections with two axillary buds and their associated leaves (left). This signalling network influences, for example, whether one bud grows and rapidly inhibits the other (middle), or whether both buds grow simultaneously (right).

Ready...set...go! In #plants, basal B-RAF activity is essential for initiating #ABA signaling under unfavorable conditions. But how is this activity maintained? Find out in this new #OpenAccess paper!🔓 doi.org/10.1111/jipb... #PlantScience #Phytohormones
Diagram describing how Clade A protein phosphatases of type 2C PP2Cs dephosphorylate B3 RAF kinases at a conserved serine residue critical for ATP binding, thereby maintaining their basal activity. Under stress, RAFs rapidly autophosphorylate this residue for autoinhibition. This mechanism ensures the precise timing and dynamics of SnRK2 activation during plant stress responses.
