Unlabelled: In higher plants, light capture of chlorophyll a/b binding protein (Lhc) plays a crucial role in the plant's response to adverse environment. So far, the family has not been systematically identified in grapes. In this study, 20 were identified in the grape genome, which were distributed in 13 of 19 grape chromosomes and divided into 7 developing branches. The results of gene duplication analysis showed that 6 formed fragment duplication events, while there was no tandem duplication in . Exon-intron structure analysis showed that they had a wide number of exons. Protein conserved motif analysis showed that contained more similar motif structures in the same phylogenetic branch. The -acting elements in the promoter region mainly respond to light, plant hormones and abiotic stresses. In addition, qRT-PCR results showed that different proportions of salt stress and red-blue light affected the expression of and the expression patterns of genes in different grape varieties were different. The results for further study on different grape varieties in different combinations of red and blue light of the Lhc provide a theoretical basis.

Foxtail millet (Setaria italica L.) is nutritionally superior to other cereals of the family Poaceae, with the potential to perform better in marginal environments. In the present context of climate change, ecologically sound and low-input foxtail millet varieties can be chosen for agricultural sustainability.

Serious neurological disorders were associated with cadmium toxicity. Hence, this research aimed to investigate the potential neuroprotective impacts of the ethanolic extracts of Citrus aurantium unripe fruits and leaves (CAF and CAL, respectively) at doses 100 and 200 mg/kg against cadmium chloride-provoked brain dysfunction in rats for 30 consecutive days. HPLC for natural pigment content revealed that CAF implied higher contents of Chlorophyll B, while the CAL has a high yield of chlorophyll A and total carotenoid.

Background: In response to iron deficiency and other environmental stressors, cyanobacteria producing siderophores can help in ameliorating plant stress and enhancing growth physiological and biochemical processes. The objective of this work was to screen the potential of Arthrospira platensis, Pseudanabaena limnetica, Nostoc carneum, and Synechococcus mundulus for siderophore production to select the most promising isolate, then to examine the potentiality of the isolated siderophore in promoting Zea mays seedling growth in an iron-limited environment.
Results: Data of the screening experiment illustrated that Synechococcus mundulus significantly recorded the maximum highest siderophore production (78 ± 2%) while the minimum production was recorded by Nostoc carneum (24.
Key Chlorophyll Molecules in the Uphill Energy Transfer from Chlorophyll to P700 in Far-Red Light-Adapted Photosystem I.

Multiple far-red light-adapted photosystem I (FR-PSI) reaction centers are recently found to work in oxygenic photosynthesis. They contain a small amount of a new type pigment chlorophyll (Chl ) in addition to the major pigment chlorophyll (Chl ). FR-PSI differs from the conventional PSIs in plants and cyanobacteria, which use only visible light absorbed by Chl , although the mechanism of FR-PSI is not fully clear yet.
