Embodiment

[0122] Hereinafter, the present invention will be described with reference to specific examples. However, the following specific examples do not limit the scope of the present invention.

[0123]

[0124] 1. Plant material

[0125] For Arabidopsis thaliana (L.) Heynh., accession Columbia-0), the following three strains having different genetic backgrounds were used.

[0126] (1) Wild strain (WT)

[0127] (2) Allantoinase gene disrupted strain (aln-1)

[0128] (3) Complementary strain of allantoinase gene disrupted strain (aln-1 35S: ALN)

[0129] These plants are the same as those used in Non-Patent Document 4. It should be noted that the complementation strain (aln-1 35S: ALN) of the allantoinase gene disrupted strain is the same as the strain indicated as "35Spro: ALN / aln-1" in the above literature.

[0130] The above (2) allantoinase gene disrupted strain (SALK_000325, Yang, J. and Han K.-H, Plant Physiology, 134:1039-1049) was obtained from the Arabidopsis Biologica...

Abstract

One of the objects of the present invention is to provide a means for increasing the resistance of plants to high temperature stress. In addition, the present invention provides an agent for improving high temperature stress resistance, which contains allantoin as an active ingredient, and is used for improving high temperature stress resistance of plants. In addition, the present invention also provides a method for improving high temperature stress resistance of plants, the method comprising applying the high temperature stress resistance improving agent to plants.

Description

technical field [0001] The invention relates to an agent for improving high temperature stress resistance of plants, a method for improving high temperature stress resistance, an albino inhibitor, and a DREB2A gene expression promoter. Background technique [0002] Plants survive by being exposed to various environmental stresses such as high temperature and dryness. Because plants have difficulty moving like animals, plants have developed mechanisms to protect themselves from environmental stressors. [0003] A dehydration responsive element (DRE; dehydration responsive element) is a sequence whose presence was confirmed in the genome of Arabidopsis thaliana by analysis of the promoter of RD29A, one of the water stress-inducible genes. DREB (DRE binding protein) is a transcription factor isolated as a protein bound to DRE. Among DREBs, DREB2A is an APETALA2 / ethylene-responsive element-binding factor-type (AP2 / ERF-type) transcription factor, and is isolated as a DRE-recogn...
