“…The relationship between the QTLs and the two resistance genes Stva and Stvb, was unknown, because the linkage map constructed in this study covered only 715 cM, which is about 47 % map length of the 12 rice chromosomes (Harushima et al 1998), and another QTL may exist. Moreover, their effects on RSV resistance differed from the findings reported by Washio et al (1968a), who identified the resistance genes Stva and Stvb, using the populations derived from the cross between a susceptible variety Kibiyoshi and upland rice varieties. The resistance level of Kibiyoshi was the same as that of Nipponbare, but the difference between these susceptible varieties may affect the results of the QTL analysis.…”

“…The Stvb gene was thought to be allelic with the other RSV resistance gene Stvb-i, which was mapped on chromosome 11 by Hayano-Saito et al (1998). These results suggested that the QTL detected on chromosome 11 corresponds to the Stvb gene, but it seemed to have a larger effect on RSV resistance than described by Washio et al (1968a). QTL analysis based on the IR obtained in the net-house test, the QTL detected on chromosome 11 explained 61.4 % of the total phenotypic variation in the F 3 population.…”

“…Furthermore, we revealed that three chromosomal segments in chromosomes 2, 6 and 11 were introgressed from URK72 into two resistant paddy lines Chugoku40 and Chugoku41. Washio et al (1968a) reported that the RSV resistance of upland rice varieties depends on a pair of complementary dominant genes Stva and Stvb. The Stvb gene was thought to be allelic with the other RSV resistance gene Stvb-i, which was mapped on chromosome 11 by Hayano-Saito et al (1998).…”

“…Rice stripe virus (RSV) is transmitted by the small brown planthopper, Laodelphax striatellus Fallen. An incompletely dominant gene, Stvb-i (Washio et al 1968b), and two dominant complementary genes, Stva (St 1 ) and Stvb (St 2 ) (Washio et al 1968a), have been identified by genetic analyses in paddy and upland rice varieties, respectively. The Stvb-i gene was introduced from the indica paddy variety Modan into japonica paddy varieties in the early 1960s to develop RSV-resistant rice varieties.…”

“…Rice stripe resistance genes, Stva and Stvb, which have been identified in Japanese upland rice varieties, show a stable and high level of resistance to RSV (Washio et al 1968a). Despite their stable resistance, these two complementary genes have not been used in paddy rice breeding programs, because it has been difficult to introduce resistance genes without also introducing undesirable characteristics of upland rice.…”

QTL Analysis for Rice Stripe Resistance in the Japanese Upland Rice Kanto72

Many Japanese upland rice varieties show a high level of resistance to rice stripe virus (RSV). This resistance is thought to be controlled by a pair of complementary dominant genes, Stva and Stvb. Quantitative trait locus (QTL) analysis for the rice stripe virus resistance was performed using 120 F 2 plants/ F 3 lines derived from a cross between the susceptible variety Nipponbare, and the resistant line Upland Rice Kanto72 (URK72). As a result, two QTLs were detected on chromosomes 2 and 11. The chromosomal regions of the two QTLs were introgressed into two resistant paddy lines Chugoku40 and Chugoku41, which were developed by introducing resistance genes from URK72. In order to verify the two QTLs, we selected two informative plants NR8 (heterozygous at the QTL on chromosome 11) and NR23 (heterozygous at the QTL on chromosome 2), from F 2 plants and we used the self-pollinated progenies of NR23 (99 plants) and NR8 (96 plants) for further QTL analyses. In these secondary analyses, one QTL was mapped near the RFLP marker G257 on chromosome 11 and the other QTL was mapped near SSR marker MS-11 on chromosome 2. Since the Stvb gene is allelic with the other RSV resistance gene Stvb-i, mapped on chromosome 11, the QTL detected on chromosome 11 was thought to correspond to the Stvb gene. However, this QTL seemed to have a larger effect on RSV resistance than previously reported and was found to contribute to the suppression of RSV infection. On the other hand, since the QTL detected on chromosome 2 did not suppress the RSV infection, it probably enhanced the QTL on chromosome 11 and suppressed the symptoms after infection by RSV.

The small brown planthopper, Laodelphax striatellus, is a destructive pest insect found in rice fields. L. striatellus not only directly feeds on the phloem sap of rice but also transmits various viruses, such as rice stripe virus (RSV) and rice black-streaked dwarf virus, resulting in serious loss of rice production. RSV is a rice-infecting virus that is found mainly in Korea, China, and Japan. To develop novel strategies to control L. striatellus and L. striatellustransmitted viruses, various studies have been conducted, based on vector biology, interactions between vectors and pathogens, and omics, including transcriptomics, proteomics, and metabolomics. In this review, we discuss the roles of saliva proteins during phloem sap-sucking and virus transmission, the diversity and role of the microbial community in L. striatellus, the profile and molecular mechanisms of insecticide resistance, classification of L. striatellus-transmitted RSV, its host range and symptoms, its genome composition and roles of virus-derived proteins, its distribution, interactions with L. striatellus, and resistance and control, to suggest future directions for integrated pest management to control L. striatellus and L. striatellustransmitted viruses.
