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 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. [...]
In this article we will discuss about the process of cybrids production. These are cytoplasmic hybrids. In cybrids, nucleus of one parent and cytoplasm of both the parents constitute cytoplasmic hybrids. More precisely, cybrids can be accomplished by fusing protoplast derived from one of the parent plants with enucleated protoplast of other. Cybrids can also be obtained through various other [...]
