Application of microRNA44a or encoding gene thereof to regulation and control of paddy rice stem length
2012
The invention discloses an application of microRNA44a or an encoding gene thereof to regulation and control of the paddy rice stem length. The invention provides an application of microRNA44a or an encoding gene thereof to regulation and control of the paddy rice stem length; and the nucleotide sequence of the microRNA44a is a sequence 3 or a sequence 4 or a sequence 2 in a sequence table. As proved by an experiment, an overexpression strain of OsmicroRAN444a is obtained by introducing an encoding gene of microRNA44a into paddy rice; and compared with paddy rice into which the gene is not introduced, the plant shows a remarkable phenotype of reduction in the stem height, which indicates that the microRNA44a is closely related to the paddy rice stem height.
