The Recretohalophyte Gene Confers Enhanced Salt Tolerance to Transgenic Hairy Root Composite Cotton Seedlings Exhibiting Virus-Induced Gene Silencing of .

The () gene encodes the plasma membrane Na/H antiporter, SOS1, that is mainly responsible for extruding Na from the cytoplasm and reducing the Na content in plants under salt stress and is considered a vital determinant in conferring salt tolerance to the plant. However, studies on the salt tolerance function of the gene of recretohalophytes, such as , are limited. In this work, the effects of salt stress on cotton seedlings transformed with tobacco-rattle-virus-based virus-induced gene silencing (VIGS) of the endogenous gene, or strain K599-mediated -transgenic hairy root composite cotton plants exhibiting VIGS of were first investigated.

Identification and functional characterization of the chloride channel gene, GsCLC-c2 from wild soybean.

Background: The anionic toxicity of plants under salt stress is mainly caused by chloride (Cl). Thus Cl influx, transport and their regulatory mechanisms should be one of the most important aspects of plant salt tolerance studies, but are often sidelined by the focus on sodium (Na) toxicity and its associated adaptations. Plant chloride channels (CLCs) are transport proteins for anions including Cl and nitrate (NO), and are critical for nutrition uptake and transport, adjustment of cellular turgor, stomatal movement, signal transduction, and Cl and NO homeostasis under salt stress.

Heterologous Expression of Confers Enhanced Salt Tolerance of Soybean Cotyledon Hairy Roots, Composite, and Whole Plants.

The gene was previously demonstrated to have high water channel activity by its heterologous expression in oocytes and in yeast; it also plays a significant role in growth of transgenic plants under favorable conditions and has enhanced tolerance toward salt and drought treatment. In this work, we first investigated the physiological effects of heterologous expression in soybean cotyledon hairy roots or composite plants mediated by toward enhanced salt tolerance. The transgenic soybean plants mediated by the pollen tube pathway, represented by the lines N and J11, were analyzed at the physiological and molecular levels for enhanced salt tolerance.
