Principles of plant nutrition
Konrad Mengel,Ernest A. Kirkby +1 more
TL;DR: In this article, the Soil as a Plant Nutrient Medium is discussed and the importance of water relations in plant growth and crop production, and the role of water as a plant nutrient medium.
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.
Journal ArticleDOI
Water relations, drought and vesicular-arbuscular mycorrhizal symbiosis
TL;DR: Vesicular-arbuscular mycorrhizal fungi can affect the water balance of both amply watered and droughted host plants and the influence of soil drying on the fungi is discussed.

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.
Journal ArticleDOI
ABA-based chemical signalling: the co-ordination of responses to stress in plants
TL;DR: It is described how a plant can use the ABA signalling mechanism and other chemical signals to adjust the amount of water that it loses through its stomata in response to changes in both the rhizospheric and the aerial environment.

Carbon Dioxide and Water Vapor Exchange in Response to Drought in the Atmosphere and in the Soil
TL;DR: In this paper, the authors describe the current hypotheses of how humidity and plant and soil water status may interact and regulate stomatal conductance and photosynthesis, and focus on the effects of 1. humidity, 2. leaf water potential and leaf turgor, and 3. soil Water status on leaf conductance, transpiration, and CO/sub 2/ assimilation.

NITROGEN ASSIMILATION AND TRANSPORT IN VASCULAR LAND PLANTS IN RELATION TO INTRACELLULAR pH REGULATION
John A. Raven,F. A. Smith +1 more
TL;DR: In this paper, it was shown that the assimilation of ammonium ion in plant cell cytoplasm produces at least one H+ per NH+4; N2 fixation generates 0.1-0.2 H+/OH per N assimilated; NO-3 assimilation produces almost one OH/OH- per NO+3.
Journal ArticleDOI
Abscisic acid-induced elevation of guard cell cytosolic Ca2+ precedes stomatal closure
TL;DR: It is reported that abscisic acid induces a rapid increase in guard cell cytosolic free Ca2+ in Commelina communisL, and that this increase precedes stomatal closure, which strongly support the sugá-gestion that Ca2- is an intracellular second messenger in this response.
Journal ArticleDOI
Soil water status affects the stomatal conductance of fully turgid wheat and sunflower leaves
TL;DR: It is concluded that the roots sensed the drying of the soil and sent a message to the leaves which induced stomatal closure, and this conductance fell with falling soil water content no matter whether the leaves were kept fully turgid or not.
Journal ArticleDOI
The responses of stomata and leaf gas exchange to vapour pressure deficits and soil water content : II. In the mesophytic herbaceous species Helianthus annuus
TL;DR: In this article, the responses of leaf water potential, leaf conductance, transpiration rate and net photosynthetic rate to vapour pressure deficits varying from 10 to 30 Pa kPa-1 were followed in Helianthus annuus as the extractable soil water decreased.
