ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Optimizing Soil Properties Through Hydrogel and Sawdust Combinations for Better Plant Growth

Journal of Plant Nutrition and Soil Science, EarlyView.
This graphical abstract illustrates the effects of various soil amendments on poplar cutting vitality under drought conditions, as observed using X‐ray computed tomography (CT). It compares soil alone, soil with sawdust, soil with hydrogel, and their combination, highlighting differences in internal structure, water retention, and root development.

Subcellular Localization of Carotenoid Biosynthesis in Synechocystis sp. PCC 6803. [PDF]

PLoS ONE, 2015
The biosynthesis pathway of carotenoids in cyanobacteria is partly described. However, the subcellular localization of individual steps is so far unknown. Carotenoid analysis of different membrane subfractions in Synechocystis sp.

Models and measurements of energy-dependent quenching. [PDF]

, 2013
Energy-dependent quenching (qE) in photosystem II (PSII) is a pH-dependent response that enables plants to regulate light harvesting in response to rapid fluctuations in light intensity.

Protein Involved in Initiation 1 Interaction With Starch Synthase 4 From Arabidopsis thaliana Induces Inhibition of Elongating Activity

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Starch is the major energy storage compound in plants. It accumulates in the form of insoluble, partly crystalline granules whose number and shape are specific to each plant species. These characteristics are defined very early in starch biosynthesis, at the initiation stage.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

The formation of homogentisate in the biosynthesis of tocopherol and plastoquinone in spinach chloroplasts [PDF]

, 1982
Homogentisate is the precursor in the biosynthesis of -tocopherol and plastoquinone-9 in chloroplasts. It is formed of 4-hydroxyphenylpyruvate of the shikimate pathway by the 4-hydroxyphenylpyruvate dioxygenase.

Biogenic retrograde signaling via GUN1 ensures thermotolerant chloroplast biogenesis during seedling establishment in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to turn green. Therefore, GUN1 helps relay heat‐related cues to maintain chloroplast biogenesis and support thermotolerance during early growth.

Effect of kinetin and chloramphenicol on chlorophyll synthesis and chloroplast development in detached lupin cotyledons under low light intensity

Acta Societatis Botanicorum Poloniae, 2015
Chlorophyll synthesis in detached lupin cotyledons under low light intensity was stimulated by kinetin at 20 mg/l and inhibited by chloramphenicol at 50 mg/1.
