5-Aminolevulinic Acid (ALA) Alleviated Salinity Stress in Cucumber Seedlings by Enhancing Chlorophyll Synthesis Pathway.
Yue Wu,Xin Jin,Weibiao Liao,Linli Hu,Mohammed Mujitaba Dawuda,Mohammed Mujitaba Dawuda,Xingjie Zhao,Zhongqi Tang,Tingyu Gong,Jihua Yu +9 more
TL;DR: The chlorophyll biosynthesis pathway was enhanced by exogenous ALA to improve the tolerance of cucumber under salinity and Ultrastructural observation of mesophyll cell showed that the damages of photosynthetic apparatus under Salinity were fixed.
Journal ArticleDOI
Exogenous spermidine is enhancing tomato tolerance to salinity–alkalinity stress by regulating chloroplast antioxidant system and chlorophyll metabolism
TL;DR: Exogenous spermidine triggers effective protection against damage induced by salinity–alkalinity stress in tomato seedlings, most likely through regulation of chlorophyll metabolism and the enzymatic and non–enzymatic antioxidant systems in chloroplast.

Exogenous GABA enhances muskmelon tolerance to salinity-alkalinity stress by regulating redox balance and chlorophyll biosynthesis
TL;DR: Exogenous GABA elevated H2O2 may act as a signal molecule, while AsA and GSH function as antioxidants, in GABA-induced salinity-alkalinity tolerance, which maintains membrane integrity which was essential for the ordered chlorophyll biosynthesis.
Journal ArticleDOI
The yellow variegated mutant of Arabidopsis is plastid autonomous and delayed in chloroplast biogenesis
TL;DR: The data suggest that var2 is delayed in chloroplast biogenesis, and it is suggested that the stochastic pattern of variegation in the mutant may be due to an interplay of factors that regulate var2 gene expression and factors that mediate rates of cell and plastid division.
Journal ArticleDOI
Phenanthrene-triggered Chlorosis is caused by elevated Chlorophyll degradation and leaf moisture.
TL;DR: It is concluded that wheat leaf chlorosis results from a combination of accelerated chlorophyll degradation and elevated leaf moisture under phenanthrene exposure, helpful not only for better understanding the toxicity of PAHs to plants and crop PAH-adaptive mechanism in the environment, but also for potentially employing the changes of thechlorophyll-synthesizing precursors and enzyme activities in plant leaves as indicators of plant response to PAH pollution.

Copper enzymes in isolated chloroplasts. polyphenoloxidase in beta vulgaris
TL;DR: Evidence that a copper enzyme, polyphenoloxidase (otherwise known as tyrosinase or catecholase), is localized in the chloroplasts of spinach beet (chard), Beta vu?garis is presented.
Journal ArticleDOI
Absorption of light by chlorophyll solutions
TL;DR: This paper deals with the estimation of chlorophyll in plant extracts by application of absorption coefficients of the isolated solid chlorophylla components, and the question of artifacts is automatically clarified.

A method for the extraction of chlorophyll from leaf tissue without maceration
J. D. Hiscox,G. F. Israelstam +1 more
TL;DR: A simple, rapid method requiring few manipulations for the extraction of chlorophylls from fragmented leaf tissue of angiosperms and gymnosperms is compared with the widely used acetone method, which makes use of incubation at 65 °C of leaf tissue immersed in dimethyl sulphoxide.
Journal ArticleDOI
Spectrophotometric characteristics of chlorophylls a and b and their pheophytins in ethanol.
TL;DR: The absorption spectra of chlorophylls a and b in 96% ethanol, and of pheophytins a andb in 80% ethanol-0.01 N hydrochloric acid have been determined in comparison with known absorption coefficients.

R. Ronen,Margalith Galun +1 more
TL;DR: In this paper, photosynthetic pigments from Romalina duriaei were extracted by immersion of the thalli in dimethyl sulfoxide (DMSO) and the extract was found to be stable in the dark at 4°C for 10 days.
