Selection and Characterization of a Novel Glyphosate Tolerant Upland Cotton(Gossypium hirsutum L.) Mutant(R1098)

Stepwise selection approach was adopted to obtain glyphosate-tolerant upland cotton mutant(R1098) from the embryogenic calli of Coker 312(Gossypium hirsutum L.).The calli were transferred to selection medium and multi-step selection pressure process was carried out until the

Cadmium-induced Functional and Ultrastructural Alterations in Roots of Two Transgenic Cotton Cultivars

The toxic effect of cadmium(Cd) at increasing concentrations has been studied with special attention being given to root morphological and ultrastructural changes in two transgenic cotton

棉花对重金属胁迫的应答反应与抗性机理研究进展

棉花是对重金属以及其它类型非生物逆境耐性较强的作物。虽然重金属胁迫对棉花的生长发育造成不利影响,但因棉花自身具有较完整的应对重金属胁迫的适应保护机制、且棉花主产品非食用的特点,可作为重金属污染土壤的修复作物。本文结合本实验室的研究结果,就国内外对镉、铬、铅、砷和汞5种主要重金属污染物源对棉花生长发育的毒害机理以及棉花应对和适应机制的研究进展作了评述。
