In this article we will discuss about the representation of gene for gene interaction in resistance development. Plants, in nature, contain several resistance genes as a defensive role. Since the turn of this century plant breeders have used these disease resistance genes commonly known as 'R' genes to counter plant disease. Knowledge about genetic and biochemical basis of plant disease [...]
In this article we will discuss about the mechanism of restoration of fertility in CMS plants. Restoration of fertility in nature is of two types, one is sporophytic and other is gametophytic. The sporophytic restorer functions before meiosis whereas gametophytic restorer acts after meiosis in pollen grain. As a consequence, a diploid plant act after meiosis in pollen grain and [...]
In this article we will discuss about the molecular basis of cytoplasmic male sterility in nature. Cytoplasmic male sterility (CMS) has been noticed over 150 plant species. CMS is a condition where plant is unable to produce functional pollen. Exploration of CMS in the production of male sterile lines eliminates hand emasculation. CMS can arise spontaneously from breeding lines due [...]
