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 ...
An overview about ultrastructure of Kranz anatomy in Cyperaceae (Poales)
(2015-01-01)
An overview about ultrastructure of Kranz anatomy in Cyperaceae (Poales) - The ultrastructure of the Kranz tissues in Cyperaceae species with the four types of Kranz anatomy (chlorocyperoid, eleocharoid, fimbristyloid and ...
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 ...
The chloroplastic DEVH-box RNA helicase INCREASED SIZE EXCLUSION LIMIT 2 involved in plasmodesmata regulation is required for group II intron splicing
(John Wiley & Sons Ltd, 2016-01-04)
INCREASED SIZE EXCLUSION LIMIT 2 (ISE2) encodes a putative DEVH‐box RNA helicase originally identified through a genetic screening for Arabidopsis mutants altered in plasmodesmata (PD) aperture. Depletion of ISE2 also ...
Expression of a plastid-targeted flavodoxin decreases chloroplast reactive oxygen species accumulation and delays senescence in aging tobacco leaves
(Frontiers Research Foundation, 2018-07)
Leaf senescence is a concerted physiological process involving controlled degradation of cellular structures and reallocation of breakdown products to other plant organs. It is accompanied by increased production of reactive ...
New insights on sucrose metabolism: Evidence for an active A/N-Inv in chloroplasts uncovers a novel component of the intracellular carbon trafficking
(Springer, 2007-11-22)
The presence of sucrose (Suc) in plastids was questioned for several decades. Although it was reported some decades ago, neither Suc transporters nor Suc metabolizing enzymes were demonstrated to be active in those organelles. ...
Mitochondrial dysfunction affects chloroplast functions
(Landes Bioscience, 2011)
The transcriptomic response of A9:u-ATP9 and apetala3:u-ATP9 lines carrying a mitochondrial dysfunction in flower tissues has been characterized. Both lines showed an alteration in the transcription of several genes involved ...
