Mutation breeding is a type of plant breeding technique that involves exposing plants to radiation or chemicals in order to induce mutations in their genetic material. This process can create new genetic variations that can potentially result in desirable traits such as improved yield, disease resistance, and enhanced nutritional value. […]
Role of Toxins in Plant Pathogenesis : The process of pathogenesis (the onset of diseased condition) in plants is facilitated by many factors such as virulence of the pathogen, susceptibility of the host, presence of suitable environmental conditions and various enzymes and metabolites of pathogens. Previously we have discussed the […]
The Folding Mystery of Chromosomes The chromosomes of eukaryotic organisms are a complex structural organization of DNA and proteins. The exact structural organization of proteins and DNA to form the chromatin material (or chromosomes during cell division) is a curious question in the scientific community. This curiosity becomes a wonder […]
What is a Karyotype? All species are characterized by a set of chromosomes to carry their genetic information. The chromosomal composition of each species has a number of characteristics. The Karyotype is a set of characteristics that identifies and describes a particular set of chromosome. These characteristics which are described […]
The size and shape of the chromosomes are variable in the different phases of cell cycle. Chromosomes in the interphase of cell appear as thin, coiled, elastic and thread-like structures. This thread-like stainable interphase chromosome is called chromatin. During the mitotic or meiotic cell division, the chromatin materials become thicker […]
