Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with accompanying drawing:

[0031] The invention discloses an RNA binding protein OsRRM, which is one of the following nucleotide sequences:

[0032] (1), the DNA sequence shown in sequence 1 in the sequence listing;

[0033] (2) A DNA sequence having more than 90% homology with the DNA sequence defined in Sequence 1 in the sequence listing and encoding the same functional protein.

[0034] On the other hand, the present invention discloses the application of RNA binding protein OsRRM in regulating sugar transport in rice.

[0035]Sugar transporter-encoding genes are regulated by a novel RNA-binding protein, OsRRM. OsRRM directly and specifically binds the mRNAs of genes encoding multiple sugar transporters and may increase their stability. Given that sugar allocation is critical for plant growth, development and yield, our study provides new directions for improving crop yield.

Abstract

The invention discloses an RNA binding protein OsRRM and application of the RNA binding protein OsRRM in regulation and control of sugar transport in rice. The RNA binding protein OsRRM is one of thefollowing nucleotide sequences: (1) a DNA sequence shown as a sequence 1 in a sequence table; and (2) a DNA sequence which has more than 90% of homology with the DNA sequence limited by the sequence 1in the sequence table and encodes the same functional protein. On the other hand, the invention discloses application of the RNA binding protein OsRRM in regulation and control of sugar transport inrice. The RNA binding protein OsRRM has the beneficial effect that an encoding gene of a sugar transporter is regulated and controlled by the new RNA-binding protein OsRRM. OsRRM directly and specifically binds to mRNA of a plurality of the multiple sugar transporter encoding genes, and may increase their stability. As the distribution of sugar is crucial to the growth, development and yield of plants, the research provides a new guidance direction for the increase of the crop yield.

Description

technical field [0001] The invention relates to the field of rice sugar transporter regulation, and mainly relates to an RNA binding protein OsRRM and its application in regulating sugar transport in rice. Background technique [0002] The partitioning of sugar between vegetative and reproductive tissues is critical for plant development, and sugar transporters play a fundamental role in this process. Although some transcription factors have been identified to participate in the regulation of sugar transporters at the transcriptional level, how they are regulated at the post-transcriptional level remains unclear. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an RNA binding protein OsRRM and its application in regulating sugar transport in rice. [0004] The purpose of the present invention is accomplished through the following technical solutions. The invention discloses an RNA bindin...
