In vitro segregation of marker genes in anther cultures of rice.
Segregation of genes controlling expression of anthocyanin pigmentation in rice (Oryza sativa L. subsp. indica) leaf blade and leaf sheath was examined in the microspore-derived plants. The segregation pattern of marker genes was found to fit closely the expected gametic segregation ratios among microspore-derived green as well as albino plants. Microspore-derived in vitro regenerated plants expressed genetic traits similar to seedlings. The results indicate that the germ cell culture technique can be of significance while monitoring gene action, i.e. anthocyanin synthesis at monoploid phase of plant development.
