UNASSIGNED: Calmodulins (CaMs) regulate numerous @entity141 -mediated cellular processes in plants by interacting with their respective downstream effectors. Due to the limited number of CaMs, other @entity460 sensors modulate the regulation of @entity141 -mediated cellular processes that are not managed by CaMs. Of 50 CaM-like (CML) proteins identified in @entity958 , we characterized the function of CML10. Yeast two-hybrid screening revealed phosphomannomutase (PMM) as a putative interaction partner of CML10. In vitro and in  vivo interaction assays were performed to analyze the interaction mechanisms of CML10 and PMM. PMM activity and the phenotypes of cml10 knock-down mutants were studied to elucidate the role(s) of the CML10-PMM interaction. PMM interacted specifically with CML10 in the presence of @entity141 through its multiple interaction motifs. This interaction promoted the activity of PMM. The phenotypes of cml10 knock-down mutants were more sensitive to stress conditions than wild-type plants, corresponding with the fact that PMM is an enzyme which modulates the biosynthesis of @entity620 , an antioxidant. The results of this research demonstrate that a @entity460 sensor, CML10, which is an evolutionary variant of CaM, modulates the stress responses in @entity958 by regulating @entity620 production.

CML10, a variant of calmodulin, modulates XXXX synthesis.
