Abstract
The ability of the shoot apical meristem to multiply and distribute its meristematic potential through the formation of axillary meristems is essential for the diversity of forms and growth habits of higher plants. In the lateral suppressor mutant of tomato the initiation of axillary meristems is prevented, thus offering the unique opportunity to study the molecular mechanisms underlying this important function of the shoot apical meristem. We report here the isolation of the Lateral suppressor gene by positional cloning and show that the mutant phenotype is caused by a complete loss of function of a new member of the VHIID family of plant regulatory proteins.
摘要
茎尖分生组织通过腋生分生组织的形成来增殖和分配其分生潜能的能力，对于高等植物形态和生长习性的多样性至关重要。在番茄的侧芽抑制突变体中，腋生分生组织的起始受到抑制，从而为研究茎尖分生组织这一重要功能的分子机制提供了独特的机会。我们在此报告通过定位克隆分离出侧芽抑制基因，并表明突变表型是由植物调节蛋白VHIID家族一个新成员的功能完全丧失所致。
