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 features and effects of gene. Essential Features of Gene: Prior to 1940, recombination was not believed to occur within genes. The genes in a chromosome were considered analogous to beads on a string. Recombination was believed to occur only between the beads or genes. The gene was not considered subdivisible. But, on [...]
In this article we will discuss about the functional activities of gene in action. The functional activity of these genes which are needed in all cell types are known as house-keeping genes and those who are active or the activities of those genes are found only in some specialized cells are known as luxury genes. But from the point of [...]
