Plant drought stress: effects, mechanisms and management
Muhammad Farooq,Muhammad Farooq,Abdul Wahid,Nobuya Kobayashi,Daisuke Fujita,Shahzad M. A. Basra +5 more
TL;DR: The effects of drought stress on the growth, phenology, water and nutrient relations, photosynthesis, assimilate partitioning, and respiration in plants, and the mechanism of drought resistance in plants on a morphological, physiological and molecular basis are reviewed.
Journal ArticleDOI
Crop Production under Drought and Heat Stress: Plant Responses and Management Options
Shah Fahad,Ali Ahsan Bajwa,Usman Nazir,Shakeel Ahmad Anjum,Ayesha Farooq,Ali Zohaib,Sehrish Sadia,Wajid Nasim,Steve W. Adkins,Shah Saud,Shah Saud,Muhammad Ihsan,Hesham F. Alharby,Chao Wu,Depeng Wang,Jianliang Huang,Jianliang Huang +16 more
TL;DR: A comprehensive account of conventional as well as modern approaches to deal with heat and drought stresses have been presented here and a side-by-side critical discussion on salient responses and management strategies for these two important abiotic stresses provides a unique insight into the phenomena.
Journal ArticleDOI
Drought tolerance improvement in crop plants: An integrated view from breeding to genomics
Luigi Cattivelli,Fulvia Rizza,Franz-W. Badeck,Elisabetta Mazzucotelli,Anna M. Mastrangelo,Enrico Francia,Caterina Marè,Alessandro Tondelli,A. Michele Stanca +8 more
TL;DR: Breeders are asked to blend together all knowledge on the traits sustaining yield under drought and to accumulate the most effective QTLs and/or transgenes into elite genotypes without detrimental effects on yield potential, which will lead to new cultivars with high yield potential and high yield stability, that will result in superior performance in dry environments.
Journal ArticleDOI
The critical role of potassium in plant stress response.
TL;DR: The emerging role of K in defending against a number of biotic and abiotic stresses, including diseases, pests, drought, salinity, cold and frost and waterlogging is focused on.

Drought stress in plants: A review on morphological characteristics and pigments composition
Cheruth Abdul Jaleel,P. Manivannan,Abdul Wahid,Muhammad Farooq,H.J. Al-Juburi,Ramamurthy Somasundaram,Rajaram Panneerselvam +6 more
TL;DR: Drought induced changes in morphological, physiological and pigments composition in higher plants are described, which results in declined light harvesting and generation of reducing powers, which are a source of energy for dark reactions of photosynthesis.

ASCORBATE AND GLUTATHIONE: Keeping Active Oxygen Under Control
Graham Noctor,Christine H. Foyer +1 more
TL;DR: A detailed account of current knowledge of the biosynthesis, compartmentation, and transport of these two important antioxidants, with emphasis on the unique insights and advances gained by molecular exploration are provided.
Journal ArticleDOI
Salt and drought stress signal transduction in plants
TL;DR: Salt and drought stress signal transduction consists of ionic and osmotic homeostasis signaling pathways, detoxification (i.e., damage control and repair) response pathways, and pathways for growth regulation.
Journal ArticleDOI
THE WATER-WATER CYCLE IN CHLOROPLASTS: Scavenging of Active Oxygens and Dissipation of Excess Photons
TL;DR: Whenever the water-water cycle operates properly for scavenging of active oxygens in chloroplasts, it also effectively dissipates excess excitation energy under environmental stress.
Journal ArticleDOI
Understanding plant responses to drought — from genes to the whole plant
TL;DR: Attention is drawn to the perception and signalling processes (chemical and hydraulic) of water deficits, which are essential for a holistic understanding of plant resistance to stress, which is needed to improve crop management and breeding techniques.

How Plants Cope with Water Stress in the Field? Photosynthesis and Growth
Maria Manuela Chaves,João Pereira,João Maroco,Maria Luísa Rodrigues,Cândido Pinto Ricardo,Maria Leonor Osório,Isabel S. Carvalho,T. Faria,Carla Pinheiro +8 more
TL;DR: Differences among species that can be traced to different capacities for water acquisition, rather than to differences in metabolism at a given water status, are described.
