The Plant Journal, Volume 127, Issue 5, September 2026.SUMMARY Photosynthesis impairment and the accompanying leaf yellowing represent a prominent and physiologically critical symptom of phytoplasma infection. However, the underlying molecular mechanisms remain poorly understood. In this study, we identified the Jujube Witches' Broom pathogenic effector PHYL1JWB, which was previously reported to induce ...

MdATG5a‐mediated autophagy improves apple performance under low light
The Plant Journal, Volume 127, Issue 5, September 2026.SUMMARY Apples are sun‐loving plants, and excessive canopy closure in orchards leads to poor ventilation and reduced light penetration, ultimately limiting yield and fruit quality. Autophagy is a conserved mechanism for recycling cellular materials and energy in eukaryotes and is known to participate in multiple stress responses.

Polypeptide composition of the purified Photosystem II pigment-protein complex from spinach
Biochimica Et Biophysica Acta - Bioenergetics, 1979The Photosystem II pigment-protein complex, the chlorophyll alpha-protein comprising the reaction center of Photosystem II, was prepared from EDTA-treated spinach chloroplasts by digitonin extraction, sucrose-gradient centrifugation, DEAE-cellulose column chromatography, and isoelectrofocussing on Ampholine.

We recently identified a 58-kDa protein kinase, PS II-PK, closely associated in substoichiometric abundance with a core complex of photosystem II and capable of phosphorylating both the photosystem and its associated light-harvesting proteins. Oxidizing species, produced during aerobic illumination, inhibited the kinase, and the irreversibility of this

Spectroscopic characterization of the Photosystem II chlorophyll-protein complexes
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1988Abstract We investigated by polarized light spectroscopy the organization of the pigments in the Photosystem II (PS II) reaction center of Chlamydomonas reinhardtii using PS II particles and subparticles of varying photochemical activity, antenna size and polypeptide composition.

Photosystem I and II chlorophyll-protein complexes of higher plant chloroplasts
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971Abstract An improved purification procedure which provides large quantities of the Photosystem I and II chlorophyll-protein complexes in a homogeneous form is reported. Only approx. 20% of the chlorophyll in the plants examined is associated with Photosystem I. Preliminary analyses of the properties of the two chlorophyll-proteins are given.

The chlorophyll-protein complexes that form the antenna system of photosystem II have been purified and analyzed in terms of the commonly observed chlorophyll spectral forms. With the exception of chlorophyll b, which is known to be associated with the complexes comprising the outer antenna (LHCII, CP24, CP26, CP29), the spectral forms occur with ...

The pyridazinone-type herbicide norflurazon SAN 9789 inhibiting the biosynthesis of long-chain carotenoids results in significant decrease in PS II core complexes and content of light-harvesting complex (LHC) polypeptides in the 29.5-21 kDa region. The Chl a forms at 668, 676, and 690 nm that belong to LHC and antenna part of PS I disappear completely ...

Multiple copies of the PsbQ protein in a cyanobacterial photosystem II assembly intermediate complex
Photosynthesis Research, 2015Photosystem II (PSII) undergoes frequent damage owing to the demanding electron transfer chemistry it performs. To sustain photosynthetic activity, damaged PSII undergoes a complex repair cycle consisting of many transient intermediate complexes. By purifying PSII from the cyanobacterium Synechocystis sp.
