TLDR
The current understanding of the mechanisms by which plants control senescence and the processes that are involved is presented.Abstract:
Senescence in green plants is a complex and highly regulated process that occurs as part of plant development or can be prematurely induced by stress. In the last decade, the main focus of research has been on the identification of senescence mutants, as well as on genes that show enhanced expression during senescence. Analysis of these is beginning to expand our understanding of the processes by which senescence functions. Recent rapid advances in genomics resources, especially for the model plant species Arabidopsis, are providing scientists with a dazzling array of tools for the identification and functional analysis of the genes and pathways involved in senescence. In this review, we present the current understanding of the mechanisms by which plants control senescence and the processes that are involved.read more

Significance of Inducible Defense-related Proteins in Infected Plants
TL;DR: The evolutionary conservation of similar defense-related proteins in monocots and dicots, but also their divergent occurrence in other conditions, suggest that these proteins serve essential functions in plant life, whether in defense or not.

Redox Regulation in Photosynthetic Organisms: Signaling, Acclimation, and Practical Implications
Christine H. Foyer,Graham Noctor +1 more
TL;DR: This review focuses on current knowledge of the pathways of redox regulation, with discussion of the somewhat juxtaposed hypotheses of "oxidative damage" versus "Oxidative signaling," within the wider context of physiological function, from plant cell biology to potential applications.

Nitrogen uptake, assimilation and remobilization in plants: challenges for sustainable and productive agriculture
Céline Masclaux-Daubresse,Françoise Daniel-Vedele,Julie Dechorgnat,Fabien Chardon,Laure Gaufichon,Akira Suzuki +5 more
TL;DR: This review presents the complexity of NUE and supports the idea that the integration of the numerous data coming from transcriptome studies, functional genomics, quantitative genetics, ecophysiology and soil science into explanatory models of whole-plant behaviour will be promising.
REVIEW: PART OF A SPECIAL ISSUE ON PLANT NUTRITION Nitrogen uptake, assimilation and remobilization in plants: challenges for sustainable and productive agriculture
TL;DR: In this paper, a review of the physiological, metabolic, and genetic aspects of nitrogen uptake, assimilation, and remobilization in crop plants is presented and the enzymes and regulatory processes manipulated to improve NUE components are also discussed.

Floral dip: a simplified method for Agrobacterium-mediated transformation of Arabidopsis thaliana
Steven J. Clough,Andrew F. Bent +1 more
TL;DR: The modified method should facilitate high-throughput transformation of Arabidopsis for efforts such as T-DNA gene tagging, positional cloning, or attempts at targeted gene replacement.

COI1: An Arabidopsis Gene Required for Jasmonate-Regulated Defense and Fertility
TL;DR: The coi1 mutation defines an Arabidopsis gene required for response to jasmonates, which regulate defense against insects and pathogens, wound healing, and pollen fertility as mentioned in this paper.
