Auxin response factor (ARF) proteins respond to biological and abiotic stresses and play important roles in regulating plant growth and development. In this study, based on the genome-wide database of sugar beet, 16 BvARF proteins were identified. A detailed investigation into the BvARF family is performed, including analysis of the conserved domains, chromosomal locations, phylogeny, exon-intron structure, conserved motifs, subcellular localization, gene ontology (GO) annotations and expression profiles of BvARF under salt-tolerant condition. The majority of BvARF proteins contain B3 domain, AUX_RESP domain and AUX/IAA domain and a few lacked of AUX/IAA domain. Phylogenetic analysis suggests that the 16 BvARF proteins are clustered into six groups. Expression profile analysis shows that most of these BvARF genes in sugar beet under salinity stress were up-regulated or down-regulated to varying degrees and nine of the BvARF genes changed significantly. They were thought to have a significant response to salinity stress. The current study provides basic information for the BvARF genes and will pave the way for further studies on the roles of BvARF genes in regulating sugar beet’s growth, development and responses to salinity stress.

This study aimed to reveal changes in morphological and physiological characters during growth and mature stages of rice plants in response to salinity stress and growth promoters. Salinity stress caused a decrease in vegetative growth, yield and yield components, while growth substances enhanced the leaf area and crop yield of rice plants under salinity stress. It could be concluded that growth promoters can partially alleviate the harmful effect of salinity stress on rice.

The study sought to evaluate the response of three groundnut genotypes (Binachinabadam-3, Dacca-1 and Zhingabadam) to various salt concentrations (D0 – Control, D1 – 2.5 dS/m, D2 – 5.0 dS/m, D3 – 7.5 dS/m, D4 – 10.0 dS/m, D5 – 12.5 dS/m) through observation of morphological and physiological characters. Based on relative performance of yield contributing characters and nutrient contents of leaves and stem, Binachinabadam-3 emerged to be a tolerant variety and based on root shoot characters, Dacca-1 appeared as tolerant while Zhingabadam always performed as sensitive variety. Salinity treatments had most adverse effects at flowering stage and followed the trend of sensitivity as flowering stage > vegetative stage> pre sowing stage > pod filling stage. All varieties were found to be tolerant up to salinity level of 7.5 dS/m.

Abstract Greenhouse pot experiments were conducted to investigate the effect of salinity stress on survival percentage and physiological parameters in three varieties of Pistacia vera L.; including ‘Sarakhs’, ‘Badami’ and ‘Akbari’. To impose salinity stress, the plants were watered with NaCl solution (250 mM). The physiological characters were investigated at 3rd, 6th and 9th days of salinity induction. Based on our results, Badami showed a greater survival percentage among the other varieties. The highest level of proline, soluble sugar, anthocyanin and glycine-betaine contents and the lowest amount of H2O2 and MDA were also detected in Badami. Large quantities of H2O2, MDA and phenolic compounds were detected in Sarakhs. The highest level of superoxide dismutase (SOD) and catalase (CAT) activity was detected in Badami, while the highest activity of polyphenol oxidase (PPO) was seen in Sarakhs. All physiological characters increased during 3rd to 9th days of salinity induction, except CAT and SOD. In conclusion, Badami was more tolerant to salinity stress in comparison with other varieties due to it’s high capacity for osmotic adjustment and antioxidant protection. The physiological parameters including proline and H2O2 contents, besides the activity of CAT can be used as biochemical markers for identification of tolerant varieties of Pistacia vera.

Net Assimilation

This study was carried out in the General Commission for Scientific Agricultural Research (GCSAR), Syria, at Der EzZour Agricultural Research Center, from 2008-2010, to examine the effect of salt conditions on some growth attributes and chlorophyll fluorescence in 10 Sugar Beet (Beta vulgaris L.) genotypes under salinity stress. Sugar beet plants were irrigated with saline water, having electrical conductivity ranged from 8.6-10 dS.m-1during first year and 8.4-10.4 dS.m-1 during second year. A randomized completely block design with three replicates was used. The results showed that all studied growth attributes, leaf area, leaf number, relative growth rate, and net assimilation rate were decreased in salinity stress conditions compared to the controlled state. The findings indicated that salinity caused a decrement of light utilizing through increased values of fluorescence origin (fo), decreased values of fluorescence maximum (fm), and maximum yield of quantum in photosystem-II (fv/fm). Genotypes differed significantly in all studied attributes except in leaf number. Under salt conditions, Brigitta (monogerm) achieved an increase in net assimilation rate, while Kawimera (multigerm) achieved the lowest decrement in quantum yield in photosystem-II. Further studies are necessary to correlate the yield with yield components under similar conditions to determine the most tolerant genotype.International Journal of Environment Vol.3(1) 2014: 1-9 DOI: http://dx.doi.org/10.3126/ije.v3i1.9937
