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 the significance of protoplast culture. Cell Modification by DNA Uptake: The isolated plant protoplasts are best suited for the introduction of foreign genetic material. Protoplast acts as an efficient receptor for the uptake of foreign DNA. Protoplast can be regenerated into the whole plant and this is indispensable for genetic manipulation. The ratio [...]
In this article we will discus about the organization of plant mitochondrial DNA. The mitochondrial genome of higher plants is the largest and complex among the eukaryotes. However, the plant mitochondrial genome does not contain many genes. The complex nature of plant mitochondrial genome might be due to the presence of many chloroplast sequences in the mtDNA of higher plants. [...]
