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 examples of transgenic plants for phytoremediation. 1. Phytoremediation of Mercury: There have been reports on the ability of certain plant species which have ability to accumulate mercury both from atmospheric and soil sources. However, plant species never ventured hyper accumulation of mercury, researcher use engineered plants by introducing bacterial specific genes for [...]
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 [...]
