Small heat shock protein 17.8 (HSP17.8) is produced abundantly in plant cells under heat and other stress conditions and may play an important role in plant tolerance to stress environments. However, HSP17.8 may be differentially expressed in different accessions of a crop species exposed to identical stress conditions. The ability of different genotypes to adapt to various stress conditions re...

introduction in agronomy, natural outlook has been expressed in different forms which stable agriculture is an example. stable agriculture is ascribed to the authentic management of agricultural resources, which in addition to fulfilling the ever-changing needs of humans, maintains the health of environment and capacity of water and soil resources. application of herbicides, besides being costl...

The world population is projected to become a staggering 8.3 billion by 2030 from about 6 billion today, which will aggravate food insecurity especially in developing countries [31]. By 2050, developing countries will account for 93% of cereal and 85% of meat demand growth [73]. In agricultural crop production systems, insects, diseases and weeds continue to threaten sustainability and account ...

The use of genome-wide association studies (GWAS) to detect quantitative trait loci (QTL) controlling complex traits has become a popular approach for studying key traits in crop plants. The goal of this study was to identify the genomic regions of barley (Hordeum vulgare L.) that impact five agronomic and one quality trait in U.S. elite barley breeding lines, as well as to identify markers tig...

drought is a natural disaster. because a significant impact on the agricultural and economy sector, it affects the lives of local residents. with using of the remote sensing, drought can be studied through its effects on plants and agriculture resulting in more accurate and effective results found for modeling drought. in this study, the efficiency of agricultural drought indicators for estimat...

Drought is a major abiotic stress impeding the yield of cereal crops globally. Particularly in Mediterranean environments, water becomes a limiting factor during the reproductive developmental stage, causing yield losses. The wild progenitor of cultivated barley Hordeum vulgare ssp spontaneum (Hsp) is a potentially useful source of drought tolerance alleles. Wild barley introgression lines like...

to evaluate the growth regulatory effect of chlormequat chloride (ccc) under drought stress conditions on three barley cultivars, a field study was conducted under badjgah agro climatic conditions (altitude 1810 m, longitude 52° 46´, and latitude 29° 50´) during 2003-2004 growing season. a randomized complete block based split- split plot of four replications was employed with two moisture leve...

Drought is a major threat to agricultural production and drought tolerance is a prime target for molecular approaches to crop improvement. To achieve meaningful results, these approaches must be linked with suitable phenotyping protocols at all stages, such as the screening of germplasm collections, mutant libraries, mapping populations, transgenic lines and breeding materials and the design of...
