The male sterility which is governed by both nuclear and cytoplasmic genes is known as Cytoplasmic Genetic Male Sterility or CGMS. While CMS is controlled by an extra-nuclear genome, nuclear gene may have the capability to restore fertility. When nuclear restoration of fertility genes (“Rf”) is available for a CMS …

Male sterility, as the name indicates, is the inability of a plant to produce a male reproductive organ, the viable pollen. Male sterility can occur due to extra-nuclear genetic or nuclear genetic conditions. Cytoplasmic Male Sterility (CMS) refers to the inability of a plant to produce viable pollens due to …

Over-wintering and/or over-summering of pathogen Over-seasoning is an evolutionary developed technique followed by many pathogens to survive the adverse period of their life cycle. It has been developed in the pathogens so that they can complete their life cycle and can spread their infections in the next year. The pathogens …

Infection When the inoculum starts procuring nutrients from the susceptible tissues of the host, the infection starts. This is the first stage from where the disease starts to develop. As the pathogen devours soluble products from the cell, various symptoms start appearing. Discolorness, malformation, necrotic areas are common in the …

(Evolution of Green Algae has three articles based on its three trends. All of these articles start and end with same paragraphs. If you want to avoid these intros, directly migrate to the point “Volvocine line of evolution” which is after the second horizontal line). Evolution of Green Algae: Tetrasporine Trend …

Algae are both eukaryotic and prokaryotic organisms that have no roots, stems or leaves but do have chloroplast and other pigments for carrying out photosynthesis. The basic structure of chloroplast consists of a series of flattened membranous vesicle called thylakoids or disc and a surrounding matrix. These thylakoids can be …
