“…The discrepancy in SLinduced stomatal closure may be due to the different materials used, intact plants and epidermal strips, which possibly results in different efficacy of GR24 such as permeability problem. It has been reported that Ca 2+ and its sensors CPKs are crucial for stomatal closing (Blatt, 2000;Bowler and Fluhr, 2000;Pei et al, 2000;Kim et al, 2010;Murata et al, 2015;Ray, 2017). OST1, a Ca 2 + -independent kinase, was found to be dispensable for SLinduced stomatal closure (Lv et al, 2018).…”

“…Calcium is known to act as a key secondary messenger in mediating stomatal closure (Blatt, 2000;Bowler and Fluhr, 2000;Pei et al, 2000;Kim et al, 2010;Murata et al, 2015;Ray, 2017). We therefore took a pharmacological approach to determine whether Ca 2+ is required for SL-triggered stomatal closure.…”

“…It was reported that exogenous Ca 2+ could promote stomatal closure (Blatt, 2000;Ray, 2017). Since we have shown that Ca 2+ plays a crucial role in SL-induced stomatal closure, we further examined the stomatal response of SL-related mutants in response to Ca 2+ .…”

“…It has long been known that calcium functions as a secondary messenger in stomatal closure (Blatt, 2000;Bowler and Fluhr, 2000;Kim et al, 2010;Murata et al, 2015;Ray, 2017). For instance, through H 2 O 2 activation of Ca 2+ -permeable cation channels, ABA triggers an increment of cytosolic Ca 2+ [(Ca 2+ ) cyt ] that includes Ca 2+ influx elevation from extracellular spaces and Ca 2+ release from intracellular stores (Pei et al, 2000).…”

Strigolactones (SLs) are known to mediate plant acclimation to environmental stress. We recently reported that SLs acted as prominent regulators in promotion of stomatal closure. However, the detailed mechanism by which SLs induce stomatal closure requires further investigation. Here we studied the essential role of the calcium (Ca 2+) signal mediating by the calcium-dependent protein kinase (CPK) in SL-induced stomatal closure. SL-induced stomatal closure was strongly inhibited by a Ca 2+ chelator and Ca 2+ channel blockers, indicating that Ca 2+ functions in SL promotion of stomatal closure. Through examining a collection of cpk mutants, we identified CPK33, potentially acting as a Ca 2+ transducer, which is implicated in guard cell SL signaling. SL-and Ca 2+-induced stomatal closure were impaired in cpk33 mutants. CPK33 kinase activity is essential for SL induction of stomatal closure as SL-induced stomatal closure is blocked in the dead kinase mutant of CPK33. The cpk33 mutant is impaired in H 2 O 2-induced stomatal closure, but not in SLmediated H 2 O 2 production. Our study thus uncovers an important player CPK33 which functions as an essential Ca 2+ signals mediator in Arabidopsis guard cell SL signaling.

Medicinal plants contain valuable compounds that have attracted worldwide interest for their use in the production of natural drugs. The presence of compounds such as rosmarinic acid, carnosic acid, and carnosol in Rosmarinus officinalis has made it a plant with unique therapeutic effects. The identification and regulation of the biosynthetic pathways and genes will enable the large-scale production of these compounds. Hence, we studied the correlation between the genes involved in biosynthesis of the secondary metabolites in R. officinalis using proteomics and metabolomics data by WGCNA. We identified three modules as having the highest potential for the metabolite engineering. Moreover, the hub genes highly connected to particular modules, TFs, PKs, and transporters were identified. The TFs of MYB, C3H, HB, and C2H2 were the most likely candidates associated with the target metabolic pathways. The results indicated that the hub genes including Copalyl diphosphate synthase (CDS), Phenylalanine ammonia lyase (PAL), Cineole synthase (CIN), Rosmarinic acid synthase (RAS), Tyrosine aminotransferase (TAT), Cinnamate 4-hydroxylase (C4H), and MYB58 are responsible for biosynthesis of important secondary metabolites. Thus, we confirmed these results using qRT-PCR after treating R. officinalis seedlings with methyl jasmonate. These candidate genes may be employed for genetic and metabolic engineering research to increase R. officinalis metabolite production.
