Impact of emerging compound droughts on forests: A water supply and demand perspective

Plant Biology, EarlyView.
This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences for ecosystem‐level functions. Abstract The intensification of climate change‐induced drought results in unprecedented tree and forest die‐offs worldwide ...

Characterization of Phytoene Desaturase Knockout Carotenoid-Deficient Microalgal Mutants Generated by Cas9-Ribonucleoprotein Complexes. [PDF]

Physiol Plant
ABSTRACT Phytoene desaturase (PDS; EC 1.3.5.5) is a key enzyme of the carotenoid biosynthetic pathway, catalyzing the desaturation of phytoene, precursor of all carotenoids. In this study, several PDS‐knockout (PDS‐KO) transformants of the chlorophyte microalga Chlamydomonas reinhardtii were generated using a reverse genetics strategy. Two single guide

Prolycopene, a Naturally Occurring Stereoisomer of Lycopene [PDF]

, 1941
In this paper we record the observation that there occurs in the variety of tomato called "tangerine tomato" a carotenoid, prolycopene, which is an isomer of lycopene; the isomeric relationship is similar to that between lycopene and neolycopene,I and in

Lactuca sativa L. losses and wastes as a source of biobased ingredients

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3577-3591, April 2026.
Abstract BACKGROUND The growing global population and increasing consumer focus on healthy eating challenge the agricultural sector to ensure both sustainable food production and safety. Lettuce (Lactuca sativa Mill.), the most cultivated leafy vegetable worldwide, can lose up to 40% of its weight during processing.

Greater climate change adaptation potential in populations of Quercus macrocarpa at edges of latitudinal gradient

New Phytologist, Volume 250, Issue 2, Page 1313-1329, April 2026.
Summary With current climate trajectories, tree populations will encounter novel selection pressures that risk local extinction if they are unable to acclimate or adapt. Within a reciprocal transplant experiment with Quercus macrocarpa L. established across a latitudinal gradient, we asked: (1) Is there genetic variation within populations?
