Leaf Phosphate Status, Photosynthesis, and Carbon Partitioning in Sugar Beet (IV. Changes with Time Following Increased Supply of Phosphate to Low-Phosphate Plants) por Rao, Idupulapati M., Terry, Norman

“…When P is resupplied, sugar phosphates increase as starch and sucrose pools decrease; this increase in leaf (chloroplast) sugar phosphates was most likely responsible for the increases in RuBP and photosynthesis and may have increased adenylate levels (through enhanced levels of ribose-5-phosphate).…”

Evaluation of calyx senescence during the ripening of ‘ Rojo Brillante’ persimmon by chlorophyll fluorescence imaging por Fathi-Najafabadi, Ayoub, Besada, Cristina, Gil, Rebeca, Calatayud, Ángeles, Salvador, Alejandra

“…During calyx senescence, desiccation and browning start from the apical part of sepals toward the base Leaf senescence in plants is related to the breakdown of chloroplast and the degradation of chlorophylls (Lim et al 2007). …”

Genetically modified tobacco (Nicotiana tabacum) plants for an increased production of wax esters por Nilsson, Linn

“…It was recently shown that WE:s can be overproduced in stably transformed tobacco plants carrying a gene fusion between two genes encoding a fatty acid reductase (FAR) and wax ester synthase (PES), thus forming a single WE-synthesizing enzyme (Aslan 2015). Chloroplast- directed overexpression of the fusion enzyme led to an 8-fold induction of WE levels (0.15 % by dry weight) in transgenic plants (Aslan et al. 2015). …”
