Usage: Strigolactones is a new plant hormone or its precursor found in recent years. It can restrain the growth of the plant braches and lateral bud. It also controls the number of branches together with auxin and cytokinin. It is highly potent germination stimulants of seeds of the parasitic weeds Striga and Orobanch.
rac-GR24 belongs to the class of Strigolactones (SL) analogues. It is the latest class of plant growth regulators, which can inhibit the growth of branches and lateral shoots of plants. It works with auxin and cytokinin to control the plant Number of branches. As a carotenoid derivative produced in the roots of plants, unicorninolide can promote the symbiotic effect of plants and soil microorganisms. In addition, in the process of interaction between plants and their parasitic plants, unicorninolide also acts as a signal molecule, which can induce the germination of seeds of parasitic plants, such as the unicorn metal (Origanche sp,).
The potential of racGR24 currently commercialized for plant protection:
1. Research and development of new herbicides: Strigolactone can induce the germination of parasitic plant seeds, and this feature can also be applied to the synthesis of new herbicides. Root parasitic weed seeds will die if they do not reach the root system of the host plant within 1 week after germination. Therefore, if proper amount of strigolactone analogue is applied before crop sowing or emergence, it can induce the germination of parasitic plant seeds to control weed production, which is an effective way to reduce the damage of parasitic plants.
2. Regulating crop plant type: Strigolactone has the function of inhibiting plant branches, so it can regulate plant branch development by controlling the synthesis and metabolism of strigolactone in the plant. For example, by artificially adding strigolactone analogs to suppress ineffective tillering of rice or wheat and breeding high-quality ideal plants.
3. Biofertilizer: Unicornolide helps the symbiotic fungi and rhizobium colonize roots of crops. From an agricultural perspective, SL can be used as an "indirect biofertilizer".
