In this article we will discuss about the rapid gene regulation by auxin. Naturally occurring hormone indole acetic acid (IAA) is the fastest known hormonal action among plant in terms of rapid cell elongation within a short span of 10-20 minutes. Auxin exhibits two types of response. One is short-term effect with 20 min leads to cell elongation. Second is [...]
In this article we will discuss about:- 1. Anther Culture Technique 2. Microspore Culture 3. Diploitization 4. Anther Vs. Pollen Culture 5. Plant Regeneration 6. Characteristics of Microspore Derived Plants 7. Ontogeny of Androgenesis. The term haploid refers to those plants which contains gametophytic number of chromosomes. Anther/pollen culture mediated production of haploid plants approves the concept of totipotency. Guha [...]
Plant culture media contains: 1. Macronutrients 2. Micronutrients 3. Adjuvant 4. Carbon Source. 1. Macronutrients: Macronutrients or macroelements are basically inorganic salts. There are six major elements indispensable for growth of plants—nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. Carbon, hydrogen and oxygen are obtained from the environment. In culture media concentration of these elements are well balanced depending on the [...]
