Abstract
The genetic transformation plays an important role in plant gene functional analysis and its genetic improvement. However, only a limited number of maize germplasms can be routinely transformed. The maize gene Wuschel-like homeobox protein 2a (Wox2a) was shown to play a crucial role in promoting the formation of embryonic cells and enhancing the efficiency of genetic transformation in maize. This commentary discusses the mechanism by which the Wox2a gene contributes to the variation in embryogenic tissue culture response among different maize inbred lines. In addition, the frequency and intensity of Wox2a or Wus2/Bbm vector-induced somatic embryogenesis was also discussed. The application of Wox2a in transformation of recalcitrant maize genotypes could well accelerate the development of maize genetic improvement.
