The rice Os02g0120500 was reported as OsTDR since the year 2006 . It is involved with pollen development in rice[1][2][3][4].

Annotated Information

Function

  • OsTDR is a key component of the molecular network regulating rice tapetum development and degeneration [1][2]. As a member of bHLH family, OsTDR is a tapetal cell death regulator[1][2][3][4]. It positively triggers programmed cell death (PCD) of tapetal cells and loss of OsTDR function could cause aborted tapetal PCD during pollen development[1][2][3].
  • In addition to its function in promoting tapetum PCD, OsTDR possibly plays some other crucial regulatory roles in several basic biological processes during rice pollen development, for example, aliphatic metabolism[2][3]. It can regulate the synthesis of lipidic precursors during rice pollen wall development which might indirectly affect anther epidermis wax formation[2].

GO assignment(s): GO:0005634, GO:0030528, GO:0045449

Wild Type & Mutations

  • The phenotype analysis made by Na Li et al. showed that there was no obvious difference between the OsTDR mutant plant and wild-type plant in vegetative and floral development (Figures 1A to 1D). However, the tdr mutant plant failed to produce any viable pollen (Figures 1A to 1D). Compared with wild-type anthers, the mutant anthers were small and white, without any mature pollen grains (Figures 1E to 1H)[1].
