棉纤维次生壁加厚期的研究进展

棉纤维是胚珠表皮细胞经分化起始、伸长、次生壁增厚和脱水成熟而形成的单细胞纤维,棉纤维细胞次生壁增厚决定棉纤维强度。利用生理或分子生物学手段,研究次生壁增厚时期的生理基础及其相关基因的表达特征,可以揭示棉纤维强度的形成机制,为进一步探索改善纤维强度的生理调控途径和运用分子手段培育高强纤维品种提供理论依据。

Research Aduance on Secondary Wall Thickening of Cotton Fiber

The mature cotton fiber is monoplast cell of cotton ovule epidermal cell,which undergoes initiation,elongation,secondary wall thickening and maturation.The secondary wall thickening of cotton fiber cell decided the cotton fiber strength.Research physiological basis and the expression character of corrective gene in the secondary wall thickening development of cotton fiber cell to open out the forming system of high strong fiber using physiological and molecular means.On this way,we can provide studying basis for the ways of physiological adjusting to improve fiber strength and cultivating of new excellent breeds using molecular means.
