Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis
(Sociedad de Biología de Chile, 2010)
Chloroplast dimorphism in leaves of Cabomba caroliniana (Cabombaceae)
(Elsevier Science, 2015-02)
Cabomba Aublet is useful as a genetic model of angiosperm evolution. Previous anatomical studies and preliminary light microscopic observations on C. caroliniana A Gray revealed the presence of dimorphic chloroplasts in ...
Structural associations between organelle membranes in nectary parenchyma cells
Main conclusion: The close association between membranes and organelles, and the intense chloroplast remodeling in parenchyma cells of extrafloral nectaries occurred only at the secretion time and suggest a relationship ...
Senescence-Associated Vacuoles, a Specific Lytic Compartment for Degradation of Chloroplast Proteins?
(Molecular Diversity Preservation International, 2014-11)
Degradation of chloroplasts and chloroplast components is a distinctive feature of leaf senescence. In spite of its importance in the nutrient economy of plants, knowledge about the mechanism(s) involved in the breakdown ...
Carbon dioxide induces minor antioxidant responses in Eucalyptus urophylla chloroplasts
Key message: Minor effect on the chloroplast antioxidant proteins was detected in Eucalyptus urophylla cultivated in high-CO2 atmosphere. Abstract: Global climate change can significantly alter plant cell metabolism. A ...
Green Light to Plant Responses to Pathogens: The Role of Chloroplast Light-Dependent Signaling in Biotic Stress
Light has a key impact on the outcome of biotic stress responses in plants by providing most of the energy and many signals for the deployment of defensive barriers. Within this context, chloroplasts are not only the major ...
Shedding light on the chloroplast as a remote control of nuclear gene expression
(Landes Bioscience, 2014-12)
Plants rely on a sophisticated light sensing and signaling system that allows them to respond to environmental changes. Photosensory protein systems -phytochromes, cryptochromes, phototropins, and ultraviolet (UV)-B ...
Rapeseed chloroplast thioredoxin-m. Modulation of the affinity for target proteins.
(Elsevier Science, 2001-04)
The stroma of higher plant chloroplasts contains two thioredoxins (Trx) with different specificity for the reduction of protein disulfide bonds. Based upon electrostatic features of domains that participate in the ...
Chloroplast functionality has a positive effect on nitric oxide level in soybean cotyledons
(Elsevier Masson, 2013-05)
The subcellular localization of NO generation in soybean cotyledons, and the relationship between NO synthesis and in vivo chloroplast performance were studied. Employing the NO probe 4-aminomethyl-2′,7′-difluorofluorescein ...
Reactive oxygen species generated in chloroplasts contribute to tobacco leaf infection by the necrotrophic fungus Botrytis cinerea
(Wiley Blackwell Publishing, Inc, 2017-12)
Reactive oxygen species (ROS) play fundamental roles in plant responses to pathogen infection, including modulation of cell death processes and defense-related gene expression. Cell death triggered as part of the hypersensitive ...
