Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Photodecomposition of Chlorophylls and Chlorophyll Derivatives

Eiyo To Shokuryo, 1969
クロロフィル, クロロフィリン, フェオフィチンおよびクロロフィル誘導体の銅クロロフィル, 銅クロロフィリンナトリウム, 鉄クロロフィリンナトリウムの光分解, さらにクロロフィルaの光分解に対する水分, 遷移金属 (Fe2+, Fe3+), L-アスコルビン酸の影響を検討し, 次の結果をえた。1. クロロフィルは著しい光分解をうけ, とくにクロロフィルaはbに比較してその光分解度が大きい。2. クロロフィリンはクロロフィルaより光に対してはるかに安定であるが光分解をうける。とくに溶液の濃度が薄いほど光分解度が増大する。3. フェオフィチンは光に対してやや不安定で光分解をうける。4.

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

Advanced Science, EarlyView.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

CHLOROPHYLL DEGRADATION

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
▪ Abstract  Although the loss of green color in senescent leaves and ripening fruits is a spectacular natural phenomenon, research on chlorophyll breakdown has been largely neglected until recently. This review summarizes knowledge about the fate of chlorophyll in degreening tissues that has been gained during the past few years. Structures of end- and

Strong enhancement of chlorophyll a concentration by a weak typhoon

, 2010
Recent studies demonstrate that chlorophyll a (chl a) concentrations in the surface ocean can be significantly enhanced due to typhoons. The present study investigated chl a concentrations in the middle of the South China Sea (SCS) from 1997-2007.

Integration of Spatiotemporal Multi‐Omics in Peach Fruit Unravels a Metabolic Niche and the Genetic Basis of Trichome‐Mediated Stress Adaptation

Advanced Science, EarlyView.
This study constructed the first spatiotemporal multi‐omics map of peach fruit and discovered a key candidate gene that synergistically regulates trichome development and drought tolerance through the jasmonic acid signaling pathway, providing insights into the coupling mechanism between development and stress resistance.

Performance Analysis of MODIS 500-m Spatial Resolution Products for Estimating Chlorophyll-a Concentrations in Oligo- to Meso-Trophic Waters Case Study: Itumbiara Reservoir, Brazil

Remote Sensing, 2014
Monitoring chlorophyll-a (chl-a) concentrations is important for the management of water quality, because it is a good indicator of the eutrophication level in an aquatic system.

SPAD-502 and atLEAF CHL PLUS values provide good estimation of the chlorophyll content for Hevea brasiliensis Müll. Arg. Leaves [PDF]

, 2020
Measurement of chlorophyll content using destructive methods is not efficient due to a large number of samples, cost, and time needed. Estimationof chlorophyll content by nondestructive methods using handheld chlorophyll meter may be considered to ...
