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

A purpose of the present invention is to provide a means for enhancing high-temperature resistance in a plant. Provided is an agent for enhancing high-temperature resistance in a plant, said agent comprising allantoin as an active ingredient. Also provided is a method for enhancing high-temperature resistance in a plant, said method comprising a step for applying the aforesaid agent for enhancinghigh-temperature resistance to the plant.

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...
