The RING zinc finger protein LbRZF1 promotes salt gland development and salt tolerance in Limonium bicolor
The recretohalophyte Limonium bicolor thrives in high-salinity environments because salt glands on the above-ground parts of the plant help to expel excess salt.Limonium bicolor is a salt-secreting halophyte with strong resistance to salinity . The salt gland is a sixteen-cell complex formed by five successive divisions of a protoepidermal cell, and this complex is composed of four secretory cells, four adjacent cells, four inner cup cells and four outer cup cell.In this study, we characterized a RING-HC-type zinc finger protein from L. bicolor named LbRZF1. LbRZF1 was highly expressed in the early developmental stage of L. bicolor and was induced by salinity
