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 [...]
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 [...]
According to Murashige of California University, micro-propagation is distinctly divided into five stages. Stage 0 — Mother Plant Selection: Before initiation of micro-propagation, selection of suitable mother plant is crucial in the whole exercise of propagation. Generally, disease free mother explant is selected for the micro-propagation to reduce contamination of cultures. Certain growth parameters of mother plant can be improved [...]
