The rice Os01g0274800 was reported as csa in 2010 by researchers from China.

Annotated Information

Gene Symbol

  • Os01g0274800 <=> CSA,csa,OsCSA
Figure 1. Comparison of the Wild Type and the csa Mutant.[1].

Function

  • CSA is a key transcriptional regulator for sugar partitioning in rice during male reproductive development.
  • This genen was shown to encode an R2R3 MYB transcription factor that was expressed preferentially in the anther tapetal cells and in the sugar-transporting vascular tissues.
  • CSA Directly Regulates MST8 in Rice and MSTs have the ability to transport a variable range of monosaccharides across membrane barriers and have been shown to play an important role in assimilate supply for sink tissue development.
  • CSA Regulates Carbon Accumulation in the Anthersand is Required for Anther Development and Pollen Maturation.The control of sugar partitioning by CSA greatly affects male reproductive tissue development in rice[1].

Phenotypic analysis

  • Carbon starved anther (csa), that showed increased sugar contents in leaves and stems and reduced levels of sugars and starch in floral organs. In particular, the csa mutant had reduced levels of carbohydrates in later anthers and was male sterile. The csa mutant had reduced accumulation of 14 C-labeled sugars in anther sink tissue.

Expression

  • The expression of MST8, encoding a monosaccharide transporter, was greatly reduced in csa anthers.
  • The CSA gene is preferentially expressed in the vascular tissue and the tapetum of the anther, as well as in other sinks[2].
  • The CSA transcripts were undetectable in stem and leaf, but detectable in root. In the sterile empty glume, which surrounds the rice flower, no CSA expression signal was observed.
  • Strong expression of CSA was detected in the lemma and palea and weaker expression in the pistil and seed.CSA is likely expressed in the anther wall layers at the early stages.[1]

Evolution

  • CSA was located between two InDel markers Z134 and Z138, which define a region of 23 kb.
