Characterization of chlorophyll binding to LIL3. [PDF]
PLoS ONE, 2018 The light harvesting like protein 3 (LIL 3) from higher plants, has been linked to functions in chlorophyll and tocopherol biosynthesis, photo-protection and chlorophyll transfer. However, the binding of chlorophyll to LIL3 is unclear.

Productivity of triticale depending on the content of photosynthesizing pigments at anthesis
Рослинництво та ґрунтознавство, 2021 Photosynthetic pigments play an important role in the accumulation of dry matter and they can be the markers of stress. Change in the ratio of chlorophyll A and B indicates physiological changes and adaptation of the organism to changes of environmental ...

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors
Advanced Materials, EarlyView.A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Chlorophyll Degradation and its Physiological Function.
Plant and Cell PhysiologyResearch on chlorophyll degradation has progressed significantly in recent decades. In the 1990s, the structure of linear tetrapyrrole, which is unambiguously a chlorophyll degradation product, was determined.

REACTIVITY OF CHLOROPHYLL a/b‐PROTEINS AND MICELLAR TRITON X‐100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]
Photochemistry and Photobiology, 1989 Abstract—The reaction of several plant chlorophyll‐protein complexes with NaBH4has been studied by absorption spectroscopy. In all the complexes studied, chlorophyllbis more reactive than Chia,due to preferential reaction of its formyl substituent at C‐7. The complexes also show large variations in reactivity towards NaBH4and the order of reactivity is:

Electrically Coded Retinomorphic Spectrophotodetector
Advanced Materials, EarlyView.Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.

Determination of Magnesium Isotopic Composition of Plant Chlorophylls Based on HPLC and MC-ICP-MS
Yankuang ceshiThe accurate determination of magnesium isotope values of chlorophyll a and chlorophyll b is particularly important for the study of magnesium biosynthesis pathways during chlorophyll formation. HPLC is required before MC-ICP-MS can be utilized, but HPLC

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology
Advanced Materials Technologies, EarlyView.The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis
Advanced Science, EarlyView.In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.
