Plants subjected to a prior dehydration stress were seen to have altered transcriptional responses during a subsequent dehydration stress for up to 5 days after the initial stress. The abscisic acid (ABA) inducible RD29B gene of Arabidopsis thaliana was strongly induced after the first stress and displayed transcriptional memory with transcript levels nine-fold higher during the second dehydrat...

The plant-specific NAC transcription factors (TFs) play important roles in regulation of diverse biological processes, including development, growth, cell division and responses to environmental stimuli. In this study, we identified the members of the NAC TF family of chickpea (Cicer arietinum) and assess their expression profiles during plant development and under dehydration and abscisic acid...

This study shows that dehydration induces imbalanced metabolism before loss of membrane integrity in desiccation-sensitive germinated radicles. Using a photoacoustic detection system, responses of CO(2) emission and fermentation to drying were analyzed non-invasively in desiccation-tolerant and -intolerant radicles of cucumber (Cucumis sativa) and pea (Pisum sativum). Survival after drying and ...

Ticks are obligate blood feeders but spend the majority of their lifetime off-host where they must contend with a multitude of environmental stresses. Survival under desiccating conditions is a determinant for habitats where ticks can become established, and water-balance characteristics of ticks have been extensively studied. However, little is known about the underlying aspects associated wit...

OBJECTIVES To determine both the prevalence and severity of dehydration of forestry workers harvesting trees in autumn and winter. METHODS Two cross-sectional observational studies were conducted on convenience samples of 103 and 79 workers in autumn and winter, respectively. The prevalence of dehydration pre- and post-shift was determined using urine specific gravity (U(SG)), and the severit...

The dehydration of theophylline monohydrate in powder and tablet forms was studied by using an infrared water-content measuring instrument.Intact theophylline powder was recrystallized from distilled water,and ground powder was obtained by grinding in a ceramic mortar with a pestle.The samples were dehydrated as follows.The intact and ground powders were placed on a plate8cm in diameter.A powde...
