Description

Meta-Topolin Riboside (MTR) is a synthetic cytokinin plant growth regulator, a ribosylated derivative of meta-topolin. This compound is valued for its potent and specific biological activity in promoting cell division and shoot proliferation in plant tissue culture. It is an essential reagent for researchers and commercial producers in plant biotechnology, agriculture, and horticulture seeking to optimize growth protocols and improve plant yield and quality.

Application

• Plant Tissue Culture: Primary application for inducing shoot formation, enhancing multiplication rates, and reducing hyperhydricity in micropropagation of various plant species.
• Agricultural Biotechnology: Used in genetic transformation protocols to improve regeneration efficiency of transgenic plants.
• Horticulture: Applied in vitro for the mass propagation of ornamental plants, fruit trees, and rare or endangered species.
• Plant Physiology Research: A key tool for studying cytokinin signaling pathways, metabolism, and their role in plant development and stress responses.
• Seed Germination & Dormancy Breaking: Can be used to stimulate seed germination and break bud dormancy in certain plant varieties.
• Cell Suspension Cultures: Employed to maintain cell division and biomass accumulation in plant cell suspension cultures for metabolite production.
