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 ...
In vivo and in vitro methylation of the elongation factor EF-Tu from Euglena gracilis chloroplast
Based on amino acid sequence similarities between the methylated elongation factor EF-Tu from Escherichia coli and the EF-Tu from Euglena gracilis chloroplast, we predicted that the latter could also be methylated in the ...
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 ...
Inhibition of ATPase from chloroplasts by a hydroxamic acid from the gramineae
-DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), a hydroxamic acid from the Gramineae involved in the resistance of cereals to aphids, inhibits. © 1983.
