Annotated Information

The gene osMGD is isolated from the submergence tolerant cultivar FR13A.

Function

OsMGD play an important role in coping various stresses for plants, which also provide us a possible approach to enhance plant multiple stresses tolerance.The enhanced expression of OsMGD may relate to photosynthesis, and play an important role during submergence.

 The full length of OsMGD cDNA was amplified using 5'- and 3'-rapid amplification of cDNA ends, and found to consist of 1,671 bp with an 

open reading frame of 1,077 bp (181-1257) encoding 358 amino acids.

 The overexpression of OsMGD improves salt tolerance in tobacco and that galactolipids, MGDG and DGDG play an important role in the regulation of chloroplast structure and function in the plant salt stress response.

Expression

  OsMGD encodes monogalactosyldiacylglycerol synthase (UDPgalactose: 1,2-diacylglycerol 3-β-D-galactosyl transferase; EC 2.4.1.46, MGDG synthase)
  Time-course studies showed that the expression of OsMGD in the rice cultivars FR13A and IR42 (submergence-susceptive cultivar) during submergence was gradually increased and that expression in FR13A was higher than in IR42. The expression of OsMGD in FR13A was influenced by benzyladenine and illumination. The accumulation of OsMGD mRNA in both FR13A and IR42 was also increased by ethephon, gibberellin, drought and salt treatment, but cold stress had no effect on the expression of the gene. These results suggest that the expression of OsMGD mRNA requires benzyladenine or illumination, and that the process is also mediated by ethephon and gibberellin. Salt and drought stress have an effect similar to that of submergence. Furthermore, the enhanced expression of OsMGD may relate to photosynthesis, and play an important role during submergence.
