|Title||HEAT-TOLERANT TOMATO MUTANT AND METHOD FOR PRODUCING SAME|
|Abstract||Provided is a heat-tolerant tomato plant having a high ability of forming seed-containing fruits under high-temperature conditions. The present invention relates to: a method for producing a heat-tolerant tomato plant, which comprises introducing a genetic mutation for improving the pollen survival rate and the ability of forming seed-containing fruits under high-temperature conditions compared with those of a wild-type plant into a tomato plant; and a heat-tolerant tomato plant having the mutation introduced thereinto.|
|Outline of related art and contending technology||
Higher plants a high temperature, low temperature, dry, salt, such as a metal, exposed to various environmental stresses. Among the various environmental stresses, thermal stress due to high temperatures to cause the growth of a plant can lead to serious disorders, world (Peet, M.M., Willits, D.H., (1998) Agric. Forest Meteorol., 92, p.191-202 large influence on the agricultural production; Hall, A.E., (2001) Crop Responses to Environment. CRC Press LLC, Boca Raton, Florida). Panel Nations (Intergovernmental Panel on Climatic Change) et al. reported that the, the effect of global warming, an average temperature of one century in the world and is raised in increments of 0.3 °C, a current in the year 2100 and is predicted to average 3 °C and the temperature rises, such a problem is more severe in the future becomes the expected (Jones, P.D., et al., (1999) Rev. Geophys., 37, p.173-199; Porter, J.R., (2005) Nature 436, p.174).
In the cultivated tomato, with domesticated anniversary, tomato pollen fertility summer due to high temperatures due to a decrease in the effects of adhesion failure, and small beads, such as a reduction in quality have been reported many growth failure. Adhesion of the effects of high temperature phase defect, pollen fertility reduction in pollen development failure and are a major cause. In order to solve such a problem, the application of heat tolerance plants using various methods have been made. As a chemical spray technology, the high-temperature stress resistance imparting agent for agricultural and horticultural plants by spraying, to reduce the high-temperature stress under high temperature conditions, in a manner conducive to healthy growth has been known (Japanese Patent Application JP-11-199419). As the gene recombinant technology, express the small heat shock protein derived from tomato by mitochondrial type, heat tolerance to the tobacco transformation is applied to a known method (Japanese Patent Application JP-2002-95370). Further, facility, as a measure of the cultivation method, the highest sensitivity to high temperature during stamen development including growth effectively only buds of the development of devices and cooled to a suitable temperature, and the effects of promoting the growth of attached also known (International Publication WO2007/058347). However, such a conventional heat tolerance in a plant of the name applying, economy, environmental load, and/or a problem with respect to workability. Therefore, the effects of high temperature stability is ensured also in the deposition of the species is an urgent need for the breeding has heat tolerance. Further, as the heat tolerance of the varieties of the seed parent breeding even under the high-normal fruit can be efficiently formed having the type required. However, such heat tolerance of the varieties of efficient breeding methods has not been established.
