Stress induced by high temperature represents a major constraint over wheat production in many production areas. Here, the comprehensive coverage of the wheat genome achievable using single nucleotide polymorphism markers was exploited to carry out a genetic analysis targeting yield components in plants exposed to high temperature stress. The mapping population was a set of doubled haploid lines derived from a cross between the cultivars Yecora Rojo and Ksu106. Both of the parental cultivars and their derived population were tested in the field in two locations over two consecutive seasons; at each site, two sowing dates were included, with the later sowing intended to ensure that the plants were exposed to high temperature stress during the grain filling period. Composite interval mapping detected 93 quantitative trait loci influencing grain yield and some related traits, along with 20 loci associated with a ?heat susceptibility index? (HSI). The loci were distributed over all 21 of the wheat chromosomes. Some of these loci were of large enough effect to be considered as candidates for the marker-assisted breeding of high temperature tolerance in wheat.

Abstract With global warming and climate change, breeding crop plants tolerant to high-temperature stress is of immense significance. tRNA 2-thiolation is a highly conserved form of tRNA modification among living organisms. Here, we report the identification of SLG1 (Slender Guy 1), which encodes the cytosolic tRNA 2-thiolation protein 2 (RCTU2) in rice. SLG1 plays a key role in the response of rice plants to high-temperature stress at both seedling and reproductive stages. Dysfunction of SLG1 results in plants with thermosensitive phenotype, while overexpression of SLG1 enhances the tolerance of plants to high temperature. SLG1 is differentiated between the two Asian cultivated rice subspecies, indica and japonica, and the variations at both promoter and coding regions lead to an increased level of thiolated tRNA and enhanced thermotolerance of indica rice varieties. Our results demonstrate that the allelic differentiation of SLG1 confers indica rice to high-temperature tolerance, and tRNA thiolation pathway might be a potential target in the next generation rice breeding for the warming globe.

Rice is one of the world’s leading food crops, and over 90% of the world’s rice production stems from Asia. In particular, an increase of 1 °C in the minimum temperature reduces the quantity of rice by 10%. Therefore, the development of rice varieties that can stably maintain the yield and quality of the rice even under these rapid climate changes is indispensable. In this study, we performed quantitative trait loci (QTL) mapping after treatment with heat stress during the booting stage in rice. We performed a QTL analysis using the Cheongcheong/Nagdong double haploid (CNDH) line and identified 19 QTLs during the 2 year analysis. Of these QTL regions, the 2.2 cM region of RM3709–RM11694 on chromosome 1 was shared among the six traits (heading date; culm length; panicle length; number of tiller; 1000 grain weight; and content of chlorophyll) examined. Rice Microsatellite (RM) 3709–RM11694 contained 27 high-temperature-tolerance candidate genes. Among the candidate genes, OsBHT showed a different gene expression level between CNDH75, which is a high-temperature tolerant line, and CNDH11 which is a susceptible line. Although some existing high-temperature-tolerant genes have been reported, OsBHT can be used more effectively for the development of heat tolerance in rice.
