In this article we will discuss about the regulation of zein gene. The molecular biology of the zein gene system is well established in plant system. Comparison of genomic and cDNA clones have shown that they are totally devoid of intervening sequences. The regulatory signals of zein is TATA box, which is found 30 bp upstream of the transcriptional initiation [...]
In this article we will discuss about:- 1. Gene Expression in Vegetative Organs 2. Gene Expression in Reproductive Organs 3. Gene Expression in Seeds 4. Gene Expression in Fruits. Successful studies on gene expression in plants are undoubtedly due to the contribution of early botanical monograph in which cytological structure and function of organs were defined. With the advent of [...]
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. [...]
