Salinity is a serious limiting factor for the growth of rhizobia. Some rhizobia are tolerant to salt stress and promote plant growth, but the mechanisms underlying these effects are poorly characterized. The growth responses and osmoprotectants in four Bradyrhizobium strains were examined under salt stress in this study. Two-dimensional electrophoresis (2-DE) and mass spectrometry were conducte...

All abiotic stresses reduce plant growth and yield. The products of stress-inducible genes which could be directly protecting against these stresses include the enzymes responsible for the synthesis of various osmoprotectants like late embryogenesis abundant (LEA) proteins, antifreeze proteins, chaperones and detoxification enzymes. Another group of gene products involved in gene expression and...

Late embryogenesis-abundant (LEA) proteins, accumulating to a high level during the late stages of seed development, may play a role as osmoprotectants. However, the functions and mechanisms of LEA proteins remained to be elucidated. Five major groups of LEA proteins have been described. In the present study, we report on the characterization of two members of soybean LEA IV proteins, basic GmP...

Many studies have been conducted to understand plant stress responses to salinity because irrigation-dependent salt accumulation compromises crop productivity and also to understand the mechanism through which some plants thrive under saline conditions. As mechanistic understanding has increased during the last decades, discovery-oriented approaches have begun to identify genetic determinants o...

The gene CaTPS2 encoding trehalose-6-phosphate (T6P) phosphatase from Candida albicans has been cloned and disrupted in this organism. The Catps2/Catps2 mutant did not accumulate trehalose but accumulated high levels of T6P. Disruption of the two copies of the CaTPS2 gene did not abolish growth even at 42 degrees C, but decreased the growth rate. In the stationary phase, the Catps2/Catps2 mutan...

Background: In general, high-quality seed is the prerequisite of an efficient bioprocess. However, in terms of sodium gluconate production by Aspergillus niger, reports have seldom focused on seed culture with rational optimization by process analysis technology, especially for carbon source effects. In this study, based on the online physiological parameter of oxygen uptake rate (OUR), and int...

Aphid infestations can cause severe decreases in soybean (Glycine max [L.] Merr.) yield. Since planting aphid-resistant soybean strains is a promising approach for pest control, understanding the resistance mechanisms employed by aphids is of considerable importance. We compared aphid resistance in seven soybean strains and found that strain Tohoku149 was the most resistant to the foxglove aphi...

The influence of seed priming with varying levels (50 and 100 mg L?1) alpha-tocopherol (Toc) was investigated in carrot plants under water-deficit conditions. For this purpose, two cultivars carrot, DC4 DC90, were selected subjected to well-watered (100% field capacity (FC)) stress (50% FC). After 21 days conditions, a significant suppression observed shoot root fresh dry weights, their lengths...

The article investigated the different concentrations of cadmium and lead salts influence to growth development barley plant shoots. As a response sprouts action ions, changes in accumulation their wet dry biomass, height sprouts, as well survival were evaluated. Since CdCl2 Pb(CH3COO)2 belong group heavy metals with strong toxic effect, when they are individually administered, there is decreas...

Abstract Salinity is one of the major abiotic stress factors that threaten crop development and sustainable food production. As a mitigation strategy, several plant growth regulators osmoprotectants have been applied to ameliorate negative effects salinity in plants. Therefore, current study aimed investigate effect foliar applications different concentrations salicylic acid proline on growth, ...
