Journal ArticleDOI
Cell Wall Metabolism in Response to Abiotic Stress.
Hyacinthe Le Gall,Florian Philippe,Jean Marc Domon,Françoise Gillet,Jérôme Pelloux,Catherine Rayon +5 more
TL;DR: The results show the need to undertake large-scale analyses, using multidisciplinary approaches, to unravel the consequences of stress on the cell wall and identify the key components that could be targeted to improve biomass production under stress conditions.
Journal ArticleDOI
Drought Stress in Wheat during Flowering and Grain-filling Periods
TL;DR: The influence of terminal drought on leaf senescence, carbon fixation, grain set and development, and drought resistance mechanisms are described and recent developments in integrated approaches for improving resistance against terminal drought in wheat are discussed.
Journal ArticleDOI
Plant biostimulants: a review on the processing of macroalgae and use of extracts for crop management to reduce abiotic and biotic stresses
TL;DR: The use of macroalgal ABs on crop plants can generate multiple benefits with reported effects including enhanced rooting, higher crop and fruit yields, freezing, drought and salt tolerance, enhanced photosynthetic activity and resistance to fungi, bacteria and virus.
Journal ArticleDOI
The impact of environmental stress on male reproductive development in plants: biological processes and molecular mechanisms.
Nico De Storme,Danny Geelen +1 more
TL;DR: This review presents the critically stress-sensitive stages of male sporogenesis (meiosis) and male gametogenesis (microspore development), and discusses the corresponding biological processes involved and the resulting alterations in male reproduction.

Effects of Drought on Gene Expression in Maize Reproductive and Leaf Meristem Tissue Revealed by RNA-Seq
Akshay Kakumanu,Madana M.R. Ambavaram,Madana M.R. Ambavaram,Madana M.R. Ambavaram,Curtis Klumas,Arjun Krishnan,Utlwang Batlang,Utlwang Batlang,Elijah Myers,Ruth Grene,Andy Pereira +10 more
TL;DR: The working hypothesis involves signaling events associated with increased ABA levels, decreased glucose levels, disruption of ABA/sugar signaling, activation of programmed cell death/senescence through repression of a phospholipase C-mediated signaling pathway, and arrest of the cell cycle in the stressed ovary at 1 d after pollination.

Reactive oxygen species and antioxidant machinery in abiotic stress tolerance in crop plants
TL;DR: The biochemistry of ROS and their production sites, and ROS scavenging antioxidant defense machinery are described, which protects plants against oxidative stress damages.
Journal ArticleDOI
PLANT COLD ACCLIMATION: Freezing Tolerance Genes and Regulatory Mechanisms
TL;DR: This review of recent advances in determining the nature and function of genes with roles in freezing tolerance and the mechanisms involved in low temperature gene regulation and signal transduction concludes that cold acclimation includes the expression of certain cold-induced genes that function to stabilize membranes against freeze-induced injury.
Plant cold acclimation: Freezing tolerance genes and regulatory mechanisms
TL;DR: A review of recent advances in determining the nature and function of genes with roles in freezing tolerance and the mechanisms involved in low temperature gene regulation and signal transduction are described in this article.
Journal ArticleDOI
Transcriptional regulatory networks in cellular responses and tolerance to dehydration and cold stresses.
TL;DR: This review article highlights transcriptional regulation of gene expression in response to drought and cold stresses, with particular emphasis on the role of transcription factors and cis-acting elements in stress-inducible promoters.
Journal ArticleDOI
Gene networks involved in drought stress response and tolerance
TL;DR: In this paper, a short review of recent progress resulting from analysis of gene expression during the drought-stress response in plants as well as in elucidating the functions of genes implicated in the stress response and/or stress tolerance are summarized.
