“…KEY MESSAGE: Map-based cloning, subcellular localization, virus-induced-gene-silencing and transcriptomic analysis reveal HvTUB8 as a candidate gene with pleiotropic effects on barley spike and leaf development via ethylene and chlorophyll metabolism. ABSTRACT: Barley lateral spikelet morphology and grain shape play key roles in grain physical quality and yield. …”

“…The encoded protein (referred to here as GhCPP1-A0A1U8HKT6) was predicted to function as a Chaperone-like protein of protochlorophyllide oxidoreductase (CPP1), which is involved with initiation of photochemical reactions of chlorophyll biosynthesis. Sequence analysis indicates it is embedded in the chloroplast envelope membrane through four transmembrane regions and contains a J-like domain that is structurally similar to the J domain of DnaJ/Hsp40 “holdase” chaperone proteins.…”
