Gene Details:

• MSU gene ID: LOC_Os03g12030
• RAPdb gene ID: Os03g0220100
• Gene Symbol: WSL4 CUT1L HMS1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
