IISER scientists identify the gene that greens plants

IISER scientists identify the gene that greens plants GS Paper III S&T (Prelims 2021) What is the news? Researchers at the Indian Institute of Science Education and Research (IISER) have identified a gene that facilitates in the greening of plants by playing a crucial role in regulating the levels of protochlorophyllide — an intermediate in the biosynthesis of the green pigment chlorophyll. The study was recently published in the prestigious U.K. journal New Phytologi

Mass Spectrometry

Mass Spectrometry Mass spectrometry is an analytical method useful for calculating the mass–to–charge ratio ( m / z) of one or more molecules. Using this, researchers can ionise or break down the compound into simple ions and then identify the molecules based on their masses. The current process of ionisation requires electrical potential of a few kilovolts, heat or high-energy ultraviolet lasers (UV-lasers). But now, a new method has been developed soft ionisation
