Genbank accession number

• HMS1 catalyzed the biosynthesis of the C26 and C28 VLCFAs, contributing to the formation of bacula and tryphine in the pollen wall, which protect the pollen from dehydration
• Under low-humidity, hms1 pollen showed poor adhesion and reduced germination on the stigmas, which could be rescued by increasing humidity
• HMS1 Interacts with HMS1I to Regulate Very-long-chain Fatty Acid Biosynthesis and the Humidity-sensitive Genic Male Sterility in Rice (Oryza sativa).
• The hms1 mutant displayed decreased seed setting at low-humidity, but normal seed setting at high-humidity
• Furthermore, both japonica and indica rice varieties with defective HMS1 exhibited HGMS, suggesting that hms1 could potentially be used in hybrid breeding

• OsCER2~OsHMS1I, WSL4~CUT1L~HMS1, A beta-ketoacyl-CoA synthase is Involved in Rice Leaf Cuticular Wax Synthesis and requires a CER2-LIKE Protein as a Cofactor, We further isolated a cofactor of WSL4, OsCER2, a homolog of Arabidopsis CER2, by coimmunoprecipitation, and confirmed their physical interaction by split-ubiquitin yeast two-hybrid experiments
• OsCER2~OsHMS1I, WSL4~CUT1L~HMS1, A beta-ketoacyl-CoA synthase is Involved in Rice Leaf Cuticular Wax Synthesis and requires a CER2-LIKE Protein as a Cofactor, Coexpression of WSL4 and OsCER2 in elo3 yeast cells yielded fatty acids up to C30
• OsCER2~OsHMS1I, WSL4~CUT1L~HMS1, A beta-ketoacyl-CoA synthase is Involved in Rice Leaf Cuticular Wax Synthesis and requires a CER2-LIKE Protein as a Cofactor, These results demonstrated that WSL4 was involved in VLCFA elongation beyond C22 and that elongation beyond C24 required the participation of OsCER2
