Proteomic analysis of arabidopsis seed germination and priming.
TLDR
A proteome analysis of the model plant Arabidopsis revealed new proteins associated with the different phases of seed germination and priming and highlighted the power of proteomics to unravel specific features of complex developmental processes such as germination. Expand
Seed germination and vigor.
TLDR
It is highlighted that germination vigor depends on multiple biochemical and molecular variables and their characterization is expected to deliver new markers of seed quality that can be used in breeding programs and/or in biotechnological approaches to improve crop yields. Expand
The specific features of methionine biosynthesis and metabolism in plants.
TLDR
A precise knowledge of the biosynthetic pathways that are responsible for homeostatic regulation of methionine and AdoMet in plants has practical implications, particularly in herbicide design. Expand
ROS production and protein oxidation as a novel mechanism for seed dormancy alleviation.
TLDR
A novel mechanism for seed dormancy alleviation is proposed that involves ROS production and targeted changes in protein carbonylation patterns and causes the oxidation of a specific set of embryo proteins. Expand
The Effect of α-Amanitin on the Arabidopsis Seed Proteome Highlights the Distinct Roles of Stored and Neosynthesized mRNAs during Germination1
TLDR
The results show that in this species the potential for germination is largely programmed during the seed maturation process, being capable of using mRNAs stored during development and germinating seeds can recapitulate at least part of the seedmaturation program. Expand
Interactions between serine acetyltransferase and O-acetylserine (thiol) lyase in higher plants--structural and kinetic properties of the free and bound enzymes.
TLDR
Over-produced Escherichia coli harboring either a plant serine acetyltransferase or this enzyme with a plant O-acetylserine (thiol) lyase is found to be highly unstable in solution, contradict the widely held belief that such a bienzyme complex is required to channel the metabolite intermediate O- acetylSerine.

Proteomic Investigation of the Effect of Salicylic Acid on Arabidopsis Seed Germination and Establishment of Early Defense Mechanisms1[W][OA]
TLDR
This molecule enhanced the reinduction of the late maturation program during early stages of germination, thereby allowing the germinating seeds to reinforce their capacity to mount adaptive responses in environmental water stress and improve seed vigor. Expand
Patterns of Protein Oxidation in Arabidopsis Seeds and during Germination1[w]
TLDR
The results indicate that the observed specific changes in protein carbonylation patterns are probably required for counteracting and/or utilizing the production of reactive oxygen species caused by recovery of metabolic activity in the germinating seeds. Expand

TLDR
Results indicate an overlap between H(2)O(2)- and *NO-signaling pathways in acclimation to salinity and suggest that the oxidation and S-nitrosylation patterns of leaf proteins are specific molecular signatures of citrus plant vigour under stressful conditions. Expand
Proteomics of Arabidopsis Seed Germination. A Comparative Study of Wild-Type and Gibberellin-Deficient Seeds1
TLDR
The proteomic analysis indicated that GAs do not participate in many processes involved in germination sensu stricto (prior to radicle protrusion), as well as the initial mobilization of seed protein and lipid reserves, while two isoforms of S-adenosyl-methionine synthetase, which catalyzes the formation of Ado-Met from Met and ATP, might represent a major metabolic control of seedling establishment.
