“…The cultivation of resistant rice varieties is the most economical, effective, and environmentally friendly strategy to manage BPH. The cultivation of such varieties will also help to conserve natural enemies, minimize pesticide use, and prevent stronger virulent BPH strains from evolving because of the continuous use of insecticides [ 1 , 2 ].…”

“…To date, at least 44 BPH-resistance genes have been mapped or cloned from wild species or indica varieties of rice, with many located on the short arm of chromosome 4, namely Bph3 , QBph4 , Bph12 , Bph15 , Bph17 , Bph20 (t), Bph30 , Bph33 , Bph35 , and Bph36 , as reviewed by Muduli et al [ 2 ], and the recently published Bph42 [ 7 ]. Five genes were reported to be on the long arm of chromosome 4: Bph6 from the Bangladesh indica variety Swarnalata (~21.4 Mb) [ 8 ], Bph27 (t) from the indica variety Balamawee (~21.3 Mb) [ 9 ], another Bph27 from Oryza rufipogon Griff.…”

Brown planthopper (BPH), a monophagous phloem feeder, consumes a large amount of photoassimilates in rice and causes wilting. A near-isogenic line ‘TNG71-Bph45’ was developed from the Oryza sativa japonica variety ‘Tainung 71 (TNG71) carrying a dominant BPH-resistance locus derived from Oryza nivara (IRGC 102165) near the centromere of chromosome 4. We compared the NIL (TNG71-Bph45) and the recurrent parent to explore how the Bph45 gene confers BPH resistance. We found that TNG71-Bph45 is less attractive to BPH at least partially because it produces less limonene. Chiral analysis revealed that the major form of limonene in both rice lines was the L-form. However, both L- and D-limonene attracted BPH when applied exogenously to TNG71-Bph45 rice. The transcript amounts of limonene synthase were significantly higher in TNG71 than in TNG71-Bph45 and were induced by BPH infestation only in the former. Introgression of the Bph45 gene into another japonica variety, Tainan 11, also resulted in a low limonene content. Moreover, several dominantly acting BPH resistance genes introduced into the BPH-sensitive IR24 line compromised its limonene-producing ability and concurrently decreased its attractiveness to BPH. These observations suggest that reducing limonene production may be a common resistance strategy against BPH in rice.

“…Therefore, it is imperative to detect more novel resistant genes and then deduce the resistance mechanism. To date, 38 BPH resistance genes/QTLs have been identified in rice varieties, including African rice varieties and wild germplasm (Du et al, 2020;Muduli et al, 2021). Among them, Bph36 is a novel BPH-resistant gene derived from two introgression lines (RBPH16 and RBPH17) developed from wild rice GX2183, which was previously reported to be resistant to BPH.…”

Comparative transcriptome-wide identification and differential expression of genes and lncRNAs in rice near-isogenic line (KW-Bph36-NIL) in response to BPH feeding

Brown planthopper (BPH) is the most devastating pest of rice in Asia, causing substantial yield losses and has become a challenging task to be controlled under field conditions. Although extensive measures have been taken over the past decades, which resulted in the evolution of new resistant BPH strains. Therefore, besides other possible approaches, equipping host plants with resistant genes is the most effective and environment-friendly technique for BPH control. Here, we systematically analyzed transcriptome changes in the susceptible rice variety Kangwenqingzhan (KW) and the resistant near-isogenic line (NIL) KW-Bph36-NIL, through RNA-seq, depicting the differential expression profiles of mRNAs and long non-coding RNAs (lncRNAs) in rice before and after BPH feeding. We observed a proportion of genes (1.48%) and (2.74%) were altered in KW and NIL, respectively, indicating different responses of rice strains against BPH feeding. Nevertheless, we characterized 384 differentially expressed long non-coding RNAs (DELs) that can be impacted by the two strains by alternatively changing the expression patterns of the respective coding genes, suggesting their certain involvement in response to BPH feeding. In BPH invasion, KW and NIL responded differently by modifying the synthesis, storage, and transformation of intracellular substances, adjusting the nutrient accumulation and utilization inside and outside the cells. In addition, NIL expressed stronger resistance by acutely up-regulating genes and other transcription factors related to stress resistance and plant immunity. Altogether, our study elaborates valuable insights into the genome-wide DEGs and DELs expression profiles of rice under BPH invasion by high throughput sequencing and further suggests that NILs can be utilized in BPH resistance breeding programs in developing high-resistance rice lines.

“…Moreover, O. nivara has shown varying degrees of resistance to the brown planthopper (BPH; Nilaparvata lugens Stal.) [23,24], indicating the availability of varying degrees of genetic diversity in terms of BPH resistance. Furthermore, O. nivara has unique traits that could be used in rice breeding, such as high micronutrient content [25] and the unique yield traits, namely, kernel characteristics [26], panicle length [27], seed weight [26], seed characteristics [28], grain yield [27,29,30], number of tillers [25] and number of panicles per plant [31].…”

Information on the genetic diversity of wild rice species in Sri Lanka is relatively meagre, though it plays a key role in crop improvement programs of cultivated rice (Oryza sativa L.). The present study was carried out to identify the morphological variation pattern of the wild populations of O. nivara in Sri Lanka. Seven populations (P1 to P7) collected from different agro-ecological regions were characterized in a common garden based on nine morphological traits. The findings revealed a high level of phenotypic variation between populations when compared to within a population. The most variable traits were the flag leaf panicle neck length (FLPNL) and flag leaf angle (FLA), whereas the least variable trait was the flag leaf length (FLL). Box plots clearly illustrated the large differentiation of phenotypic traits in the entire distribution of wild rice populations. The cumulative values of the two principal components, i.e., FLPNL and FLA, explained 58.7% of the total variance. Populations from similar natural habitats clustered together. The P7 was adapted to intercept more sunlight by increasing flag leaf width (FLW) and FLA to compete with weeds and other shrubs. P2 and P5 were the most closely related populations representing approximately similar ecological conditions of the dry zone. The P3 population from the intermediate zone showed a vigorous plant growth with the highest plant height, culm girth and awn length (P < 0.05). Knowledge of such morphological diversity would facilitate designing conservation strategies and basic information for the proper utilization of wild resources in rice genetic improvement.
