The degradation of chloroplast proteins is an important occurrence in the mobilization of
nutrients from senescing leaves to reproductive organs during senescence. Recently, we …

Plastids bear their own genome, organized into DNA–protein complexes (nucleoids).
Recently, we identified a DNA-binding protease (CND41) in the chloroplast nucleoids of …

Arabidopsis RD21 is a cysteine protease of the papain family. Unlike other members of the
papain family, RD21 has a C-terminal extension sequence composed of two domains, a 2 …

Chloroplast protein degradation is known to occur both inside chloroplasts and in the
vacuole. Genes encoding cysteine proteases have been found to be highly expressed …

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 …

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 …

A proteomics approach has been used to study changes in protein abundance during leaf
senescence in white clover. Changes in cell ultrastructure were also examined using …

Cysteine protease inhibitors delayed the senescence of Sandersonia aurantiaca Hook.
flowers. Tepal fading and wilting occurred later in the 2, 2´-dipyridyl-treated flowers, and …

Senescence-associated proteolysis in plants is a complex and controlled process, essential
for mobilization of nutrients from old or stressed tissues, mainly leaves, to growing or sink …

Carbon (C) and nitrogen (N) are essential elements for metabolism, and their availability,
called the C/N balance, must be tightly coordinated for optimal growth in plants. Previously …
