Factors responsible for deep-sowing tolerance in wheat seedlings: varietal di…

Background and Aims A wheat cultivar, Triticum aestivum ‘Hong Mang Mai’, shows tolerance to deep-sowing conditions by extreme elongation of the first internode, likely mediated by the gibberellin (GA) response. To understand factors involved in the response of this deep-sowing-tolerant cultivar, cell expansion and division that confer elongation on the first internodes of wheat seedlings w…
