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.

Single‐Cell Transcriptomics Reveals FLS2‐Dependent Hypoxia Signaling and ERF13‐Mediated Transcription During flg22‐Triggered Immunity

Advanced Science, EarlyView.
This study employs sc‐RNA sequencing, genetics, and phenotyping to systematically map the cell‐type‐specific immune responses triggered by flg22. It reveals FLS2‐dependent transcriptional reprogramming in epidermal and mesophyll cells, and uncovers crosstalk between immune and hypoxia signaling pathways.

Effect of Controlled Atmosphere Storage Conditions on the Chemical Composition of Super Hardy Kiwifruit

Agronomy, 2020
Super hardy kiwifruit [Actinidia kolomikta (Maxim. & Rupr.) Maxim.] accumulate large amounts of biologically active compounds, but it is possible to store ripe fruit for a very short time, only 2 weeks at 0–5 °C.

REACTIVITY OF CHLOROPHYLL a/b-PROTEINS AND MICELLAR TRITON X-100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]

, 1989
The reaction of several plant chlorophyll-protein complexes with NaBH4 has been studied by absorption spectroscopy. In all the complexes studied, chlorophyll b is more reactive than Chi a, due to preferential reaction of its formyl substituent at C-7 ...

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

Coupled Above‐ and Belowground Ecosystem Stability Worldwide

Advanced Science, EarlyView.
Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

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

RELAÇÃO ENTRE O TEOR ABSOLUTO E RELATIVO DE CLOROFILA EM FOLHAS DE VIMEIRO

Ciência Florestal, 2016
The traditional methods for chlorophylls quantification in leaves are destructive, time consuming and expensive. One alternative to the destructive methods involve the use portable devices, such as the chlorophyll meter SPAD-502, which ...

Investigations of chlorophyll interactions in Water Soluble Chlorophyll Binding Protein [PDF]

, 2016
Line narrowing spectroscopy was applied to water soluble chlorophyll binding protein (WSCP) containing only 2 chlorophylls. It was compared to natural occurring 4 chlorophyll WSCP.
