Predisposition of trees to drought stress by ozone [PDF]

Tree Physiology, 1999
This paper reviews research on the effects of ozone on stomatal behavior, and draws attention to the direct link between stomatal function and air pollution. Contradictory results concerning the effects of air pollutants on stomatal activity are attributed to the use of univariate statistical treatments of data.

Identification of Drought-Responsive Universal Stress Proteins in Viridiplantae

, 2011
Genes encoding proteins that contain the universal stress protein (USP) domain are known to provide bacteria, archaea, fungi, protozoa, and plants with the ability to respond to a plethora of environmental stresses.

Effect of drought stress on yield, proline and chlorophyll contents in three chickpea cultivars

, 2010
Drought stress is one of the major abiotic stresses in agriculture worldwide. This study was carried out to investigate the effect of drought stress on proline content, chlorophyll content, photosynthesis and transpiration, stomatal conductance and yield

Down-regulation of CBP80 gene expression as a strategy to engineer a drought-tolerant potato [PDF]

, 2012
Developing new strategies for crop plants to respond to drought is crucial for their innovative breeding. The down-regulation of nuclear cap-binding proteins in Arabidopsis renders plants drought tolerant.

Farmers' stress and coping in a time of drought

Rural and Remote Health, 2012
Farmers as a group have unique attitudes, sources of stress and a heightened risk of suicide. In the context of a prolonged drought and associated stress and increased risk of mental-health problems, this study provides an insight into the levels of psychological distress experienced by different demographic groups within the Australian farming ...

Effect of drought stress and subsequent recovery on protein, carbohydrate contents, catalase and peroxidase activities in three chickpea (Cicer arietinum) cultivars

, 2011
Drought stress is one of the major abiotic stresses in agriculture worldwide. This study was carried out to investigate the effects of drought stress and subsequent recovery on protein, carbohydrate content, catalase (CAT), and peroxidase (POX ...

Effects of Drought on Nutrient Uptake and Assimilation in Vegetable CropsPlant Responses to Drought Stress

, 2012
Scarcity of water is a severe environmental limit to plant productivity. Drought-induced loss in crop yield probably exceeds losses from all other causes, since both the severity and duration of the stress are critical.

Photosynthetic performance and sucrose metabolism in superior and inferior rice grains with overlapping growth stages under water stress

Scientific Reports
Drought stress at jointing and booting stages of plant development directly affects plant growth and productivity in rice. Jointing and booting stages may overlap in high-latitude areas where water deficits occur.

Tetrapyrrole‐based drought stress signalling

Plant Biotechnology Journal, 2015
SummaryTetrapyrroles such as chlorophyll and heme play a vital role in primary plant metabolic processes such as photosynthesis and respiration. Over the past decades, extensive genetic and molecular analyses have provided valuable insights into the complex regulatory network of the tetrapyrrole biosynthesis.
