Switching colors – feedback control of carotenoid biosynthesis in Arabidopsis

Plants need to coordinate the biosynthetic activities present in different compartments. This is challenging especially for pathways localized within organelles, e.g. plastids, as most of the genetic information was transferred into the nucleus during the establishment of

Antireductants – essential counterparts of antioxidants

The hype around ‘antioxidants for health’ largely overshadows the existence of antireductants. While antioxidants by definition decrease oxidative stress, antireductants decrease reductive stress (Fig. 1). Despite opposite reactivities, antioxidants and antireductants have in common that they are

β-Carotene requirement for anti-aging depends on genetic background

Cellular telomere, a region of repetitive nucleotide sequences of TTAGGG, resides on both ends of chromosomes and its length is shortened by reflecting the replication number of chromosomal DNA, accordingly, telomere length is the most reliable indicator
