Background: Isoprenoid lipids in Arabidopsis chloroplasts include chlorophyll, carotenoids,…
Altering chloroplast biogenesis leads to increased yields in rice
Plant Science Research WeeklyTranscription of chloroplast genes is carried out by the plastid encoded polymerase (PEP) with help from PAPs (PEP-associated proteins). PAP3 is important for chloroplast development in Arabidopsis thaliana and Nicotiana benthamiana, however its role in crops has not been fully elucidated. Here Seo et…
Mechanism behind ripened green bananas under high temperature
Plant Science Research WeeklyHeat stress is a common consequence of global warming for terrestrial plants, and it can have devastating effects on growth and yield. In terms of fruit ripening, high temperature is one of the most significant abiotic stresses inhibiting quality formation. During fruit ripening, chlorophyll breaks down…
