DWD (DDB1 binding WD40) proteins have been reported as substrate receptors for cullin-RING ubiquitin ligase 4 complexes (CRL4), a family of E3 ligases. Abscisic acid (ABA) plays an important role in plant responses to abiotic stresses, such as drought and salinity. Upon screening T-DNA mutants of DWD genes for ABA responses we obtained several candidates that exhibited ABA-hypersensitivity, and...

Melatonin is involved in multiple plant developmental processes and various stress responses. To explore the roles of melatonin played as well as its association with abscisic acid (ABA) in a process of drought priming-induced cold tolerance (DPICT), a wild-type barley and its ABA-deficient mutant Az34 counterpart were selected for comparison, in which the effects of melatonin application (eith...

Arabidopsis thaliana HOOKLESS1 (HLS1) encodes a putative histone acetyltransferase with known functions in seedling growth. Here, we show that HLS1 regulates plant responses to pathogens and abscisic acid (ABA) through histone acetylation at chromatin of target loci. The hls1 mutants show impaired responses to bacterial and fungal infection, accelerated senescence, and impaired responses to ABA...

The wild wheat Aegilops tauschii Coss. has extensive natural variation available for breeding of common wheat. Drought stress tolerance is closely related to abscisic acid (ABA) sensitivity. In this study, 17 synthetic hexaploid wheat lines, produced by crossing the tetraploid wheat cultivar Langdon with 17 accessions of Ae. tauschii, were used for comparative analysis of natural variation in d...

The impact of the work that we do daily, what the value of these efforts will be to those who follow us, and what the challenges will be to providing high-quality burn care are issues that we must understand if we are to build to the future. As a society, we can look to our past to gain important insights about what the future may hold and the problems we will encounter. The past also allows us...

The phytohormone abscisic acid (ABA) plays a key role in the plant response to drought stress. Hence, ABA-dependent gene transcription and ion transport is regulated by a variety of protein kinases and phosphatases. However, the nature of the membrane-delimited ABA signal transduction steps remains largely unknown. To gain insight into plasma membrane-bound ABA signaling, we identified sterol-d...

The burn injury can one of the most serious and devastating injuries among people of all ages. The aim of the study was to identify correlates of physical and psychosocial functioning among burn patients. The study was conducted at the burn units of El-Mansoura University Hospital. Design: descriptive correlational design was used. Tools which were used for data collection: 1) Sociodemographic ...

Cross-border medical support activities began with the Committee of Five, the predecessor of the International Committee of the Red Cross, which was established in 1863.1 In Japan, in addition to the Japanese Red Cross Society, the Japan Medical Association Team (JMAT)2,3 is relied on for medical support in disaster-affected areas. JMAT was active in providing aid in the aftermath of the Great ...
