Borniego M, Molina M, Guiamet J, Martinez D
Front Plant Sci
. 2020 Jan;
10:1635.
PMID: 31969890
The apoplast, i.e. the cellular compartment external to the plasma membrane, undergoes important changes during senescence. Apoplastic fluid volume increases quite significantly in senescing leaves, thereby diluting its contents. Its...

Front Plant Sci
. 2019 Jul;
10:747.
PMID: 31275332
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 metalloproteases were detected...

Gergely Z, Martinez D, Donohoe B, Mogelsvang S, Herder R, Staehelin L
J Biol Res (Thessalon)
. 2018 Aug;

PMID: 30116723
Background: The insect-trapping leaves of provide a model for studying the secretory pathway of an inducible plant secretory system. The leaf glands were induced with bovine serum albumin to secrete...

Martinez D, Costa L, Guiamet J
Methods Mol Biol
. 2018 Feb;
1744:283-297.
PMID: 29392673
Plant senescence is accompanied by a marked increase in proteolytic activities, and cysteine proteases (Cys-protease) represent the prevailing class among the responsible proteases. Cys-proteases predominantly locate to lytic compartments, i.e.,...

Carrion C, Martinez D, Costa M, Guiamet J
Plants (Basel)
. 2016 May;
3(4):498-512.
PMID: 27135516
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...

Martinez D, Borniego M, Battchikova N, Aro E, Tyystjarvi E, Guiamet J
J Exp Bot
. 2014 Nov;
66(1):161-74.
PMID: 25371504
Senescence involves increased expression of proteases, which may participate in nitrogen recycling or cellular signalling. 2D zymograms detected two protein species with increased proteolytic activity in senescing leaves of Arabidopsis...

Carrion C, Costa M, Martinez D, Mohr C, Humbeck K, Guiamet J
J Exp Bot
. 2013 Oct;
64(16):4967-80.
PMID: 24106291
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...

Martinez D, Costa M, Gomez F, Otegui M, Guiamet J
Plant J
. 2008 Jun;
56(2):196-206.
PMID: 18564383
Massive degradation of photosynthetic proteins is the hallmark of leaf senescence; however the mechanism involved in chloroplast protein breakdown is not completely understood. As small 'senescence-associated vacuoles' (SAVs) with intense...

Haas T, Sliwinski M, Martinez D, Preuss M, Ebine K, Ueda T, et al.
Plant Cell
. 2007 May;
19(4):1295-312.
PMID: 17468262
In yeast and mammals, the AAA ATPase Vps4p/SKD1 (for Vacuolar protein sorting 4/SUPPRESSOR OF K(+) TRANSPORT GROWTH DEFECT1) is required for the endosomal sorting of secretory and endocytic cargo. We...

Martinez D, Bartoli C, Grbic V, Guiamet J
J Exp Bot
. 2007 Jan;
58(5):1099-107.
PMID: 17218544
Cellular proteins are extensively degraded during leaf senescence, and this correlates with an up-regulation of protease gene expression, particularly cysteine proteases. The objectives of this work were (i) to detect...
