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 [...]
The following points highlight the top six plant promoters for genes. The promoters are: 1. Core Promoter 2. Light Responsive Promoters 3. Stress Responsive Promoters 4. Plant Hormonal Responsive Promoters 5. Sucrose Responsive Promoters 6. Low-Oxygen Responsive Promoters. 1. Core Promoter: Core promoter elements are defined as minimal promoter that contain TATA box. These are indispensable for initiation of transcription [...]
