In vivo inhibition of cysteine proteases provides evidence for the involvement of ‘senescence-associated vacuoles’ in chloroplast protein degradation during dark-induced senescence of tobacco leaves
(Oxford University Press, 2013-07)
Breakdown of leaf proteins, particularly chloroplast proteins, is a massive process in senescing leaves. In spite of its importance in internal N recycling, the mechanism(s) and the enzymes involved are largely unknown. ...
Chloroplast protein degradation in senescing leaves: Proteases and lytic compartments
(Frontiers Media, 2019-06-19)
Leaf senescence is characterized by massive degradation of chloroplast proteins, yet the protease(s) involved is(are) not completely known. Increased expression and/or activities of serine, cysteine, aspartic, and ...
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 ...
Nitrogen fertilization increases ammonium accumulation during senescence of barley leaves
(Springer Heidelberg, 2016-04)
Leaf senescence is a developmental process characterized by two events: (1) dismantling of the photosynthetic apparatus and, (2) nitrogen remobilization to other parts of the plant. Ammonium accumulation during senescence ...
Application of low intensity light pulses to delay postharvest senescence of Ocimum basilicum leaves
(Elsevier Science, 2013-12)
Fresh basil (Ocimum basilicum L.) is a highly perishable leafy green vegetable with a storage life of 4–5 d at room temperature. Exposure of basil leaves to temperatures below 12 ◦C during storage results in chilling injury; ...
