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 processing of pre-snoRNA into mature RNA. Small nucleolar RNAs are families of small RNAs involved in RNA metabolite and gene expression in eukaryotes. Their major function is in processing and modification of ribosomal RNA (rRNA). In plants, the 5.8S 18S and 28S rRNA of the cytoplasm ribosomes are produced by processing a [...]
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 [...]
