“…However, there are very few species in which SnRK2 proteins are divided into four subgroups, such as MpSnRK2 [ 50 ] and OsSAPK2 [ 51 ]. Evolutionary studies based on the sequences of algae [ 52 ], moss, ferns and angiosperms (including Arabidopsis and rice) show that seed plants contain all groups of SnRK2; fern SnRK2 belongs to groups 4 and 3, bryophytes contain only group 3 members [ 53 ] and SnRK2 from algae is different from that in higher plants in sequence. These results indicate a possible evolutionary pattern of plant SnRK2s.…”

“…biosynthesis and catabolism was upregulated in the ethanoltreated plants (Supplementary Tables S1 and S2), resulting in rapid ABA metabolic changes; (ii) the whole shoots and roots were used for ABA measurements, and the increased ABA accumulation might occur in specific cells (Kuromori et al 2022) and (iii) unknown mechanisms might be involved in the ethanolmediated drought tolerance in plants. A group of ethylenereceptor-related sensor histidine kinases is essential for ABA and osmostress responses in the moss Physcomitrium patens (Toriyama et al 2022), and a similar mechanism might contribute to the ethanol-mediated drought tolerance in plants.…”

“…The EDR1 domain might be important for interaction with other molecules that regulate the activity of B3-Raf. We recently reported that sensor-histidine kinases (HK) can interact with ARK and that the knockout mutants of HK showed little response to ABA and osmostress in P. patens ( Toriyama et al, 2022 ). An N-terminal deletion of ARK to a domain adjacent to the EDR1 domain abolished the interaction with HK, whereas a deletion to the PAS domain alone did not affect interaction with HK or response to ABA ( Toriyama et al, 2022 ).…”

A functional comparison of B3-Raf paralogs of M. polymorpha with deletions and point mutations in the EDR1 domain would reveal the role of this domain in interaction with HK and responses to ABA/osmostress.…”
