Effects of Chilling on the Structure, Function and Development of Chloroplasts
Frontiers in Plant Science, 2018 Chloroplasts are the organelles that perform energy transformation in plants. The normal physiological functions of chloroplasts are essential for plant growth and development.

ROS production and signalling in chloroplasts: cornerstones and evolving concepts
The Plant Journal, 2022 SUMMARY Reactive oxygen species (ROS) such as singlet oxygen, superoxide (O2 ●−) and hydrogen peroxide (H2O2) are the markers of living cells. Oxygenic photosynthesis produces ROS in abundance, which act as a readout of a functional electron transport ...

Function of Chloroplasts in Plant Stress Responses
International Journal of Molecular Sciences, 2021 The chloroplast has a central position in oxygenic photosynthesis and primary metabolism. In addition to these functions, the chloroplast has recently emerged as a pivotal regulator of plant responses to abiotic and biotic stress conditions. Chloroplasts

American Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022 Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

American Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022 Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Whole‐genomic DNA amplifications from individually isolated sweet sorghum microspores
Applications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022 Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

Sensitivity and Responses of Chloroplasts to Heat Stress in Plants
Frontiers in Plant Science, 2020 Increased temperatures caused by global warming threaten agricultural production, as warmer conditions can inhibit plant growth and development or even destroy crops in extreme circumstances.

COPPER ENZYMES IN ISOLATED CHLOROPLASTS. POLYPHENOLOXIDASE IN BETA VULGARIS.
Plant Physiology, 1949 The chloroplast, as the seat of chlorophyll pigments in plants, occupies a unique position in the economy of the green cell. In recent years there has been a renewed interest in the reactions and properties of chloroplasts as a result of the work of Hill

Regulation of Iron Homeostasis and Use in Chloroplasts
International Journal of Molecular Sciences, 2020 Iron (Fe) is essential for life because of its role in protein cofactors. Photosynthesis, in particular photosynthetic electron transport, has a very high demand for Fe cofactors.

The Diverse Modes of Oxygen Reactivity in Life & Chemistry
ChemSusChem, Volume 15, Issue 24, December 20, 2022., 2022 Breath of life: Oxygen is the quintessential molecule of life on our planet. Three molecular oxygen species dominate natural and artificial oxygenation reactions: the singlet and triplet spin states of dioxygen and ozone. This Review summarizes key applications of these molecular oxygen species in biology, medicine, technologies, and laboratories ...
