Abstract
Expansins found in the cell wall have the unique ability to induce immediate cell wall extension In this study a βexpansin gene TaEXPB23 isolated from wheat Triticum aestivum L coleoptiles was transformed to tobacco Nicotiana tabacum to investigate its role in plant growth and development TaEXPB23 was preferentially expressed in wheat coleoptile and a close correlation between TaEXPB23 expression and coleoptile growth was observed The overexpression of TaEXPB23 in tobacco also resulted in accelerating growth of leaves and internodes at earlier developmental stages and it was involved in regulating plant development
