Senescence-associated proteases in plants
(Wiley Blackwell Publishing, Inc, 2012-05)
Senescence is the final developmental stage of every plant organ, which leads to cell death. It is a highly regulated process, involving differential gene expression and outstanding increment in the rate of protein ...
Indole-3-acetic acid attenuates the fungal lesions in infected potato tubers
(Wiley Blackwell Publishing, Inc, 2006-04-28)
In this report, we demonstrated that potato tubers pre-treated with 100 μM of indole-3-acetic acid (IAA) and then inoculated with Fusarium solani f. sp. eumartii (F. eumartii) showed a decrease in the fungal lesion compared ...
Non-structural carbohydrates and sugar export in grapevine leaves exposed to different light regimes
(Wiley Blackwell Publishing, Inc, 2020-10)
Light is a main environmental factor that determines leaf microclimate within the vine, as well as its photosynthesis and carbohydrate metabolism. This study aimed to examine the relationships between photosynthesis, ...
ASR1, a stress-induced tomato protein, protects yeast from osmotic stress
(Wiley Blackwell Publishing, Inc, 2006-05)
Asr1, a tomato gene induced by abiotic stress, belongs to a family, composed by at least three members, involved in adaptation to dry climates. To understand the mechanism by which proteins of this family seem to protect ...
Tomato pollen tube development and carbohydrate fluctuations in the autotrophic phase of growth
(Springer Heidelberg, 2012-11)
Ripe pollen has different soluble and insoluble carbohydrates in variable amounts. Pollen germination and pollen tube growth were studied in a tomato cultivar (Solanum lycopersicum L. cv. Platense) with atypical pollen ...
Identification of regulatory elements involved in expression and induction by sucrose and UV-B light of the Arabidopsis thaliana COX5b-2 gene, encoding an isoform of cytochrome c oxidase subunit 5b
(Wiley Blackwell Publishing, Inc, 2009-11)
The promoter sequences required for expression of the Arabidopsis thaliana COX5b-2 gene, encoding an isoform of cytochrome c oxidase subunit 5b, were analyzed using plants transformed with deleted and mutagenized forms of ...
Leaf protein allocation across the canopy and during senescence in earlier and later senescing maize hybrids, and implications for the use of chlorophyll as a proxy of leaf N
(Springer Heidelberg, 2019-08-01)
Leaf chlorophyll (chl) and protein distribution were analyzed throughout grain flling in four modern maize hybrids with contrasting senescence behavior, at three diferent canopy levels and at low-N (LN, 18 kg N ha−1) and ...
Genome editing in potato via CRISPR-Cas9 ribonucleoprotein delivery
(Wiley Blackwell Publishing, Inc, 2018-12)
Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein-9 (CRISPR-Cas9) can be used as an efficient tool for genome editing in potato (Solanum tuberosum). From both a scientific and a ...
Expression and characterization of recombinant cytosolic NAD+-dependent malate dehydrogenase from Mesembryanthemum crystallinum
(Wiley Blackwell Publishing, Inc, 2003-02)
An NAD+-dependent cytosolic malate dehydrogenase (MDH, EC 1.1.1.37) from leaves of Mesembryanthemum crystallinum in the Crassulacean Acid Metabolism (CAM) mode was cloned, expressed in E. coli and characterized. The ...
Subtilisin-like serine proteases involved in N remobilization during grain filling in wheat
(Springer Heidelberg, 2011-09)
The induction of two subtilisin-like proteases (P1 and P2) associated with stress-induced senescence in young plants was investigated in adult wheat plants during the grain-filling period. Western blot analysis of flag ...
