Proteome analysis of Nilaparvata lugens cuticle

ABSTRACT: The brown planthopper (BPH, Nilaparvata lugens) is the most destructive pest of rice and causes serious economic damage in Asia. Understanding the composition of Nilaparvata lugens protein will help pest control. In this study, shotgun MS/MS analysis was performed.

ACL1-HD-Zip IV complex revealed common mechanism in rice response to brown planthopper and drought. Being a small peptide, ACL1 might function through forming complex with other proteins. So that we searched the possible interacting proteins of ACL1 using the TurboID system.

Project description:Brown planthopper (BPH) is the most notorious insect pest to rice. Drought is the most commonly occurring global adversity. BPH infestation caused adaxially-rolled leaves and shrunk bulliform cells similar to drought. The bulliform-cell characteristic gene, ACL1, negatively regulated BPH resistance and drought tolerance, with decreased cuticular wax in ACL1-D, which resulted in quicker water losing. ACL1 was specifically expressed in epidermis. TurboID system and various biochemical assays revealed that ACL1 interacted with the epidermal-characteristic HD-Zip IV ROCs. ROC4 and ROC5 positively regulated BPH resistance and drought tolerance through modulating cuticular wax and bulliform cells respectively. Overexpression of ROC4 and ROC5 both rescued ACL1-D in various related phenotypes simultaneously. Moreover, ACL1 competed with ROC4 and ROC5 in homo-dimerization and hetero-dimerization. Altogether, we illustrated that ACL1-ROCs complex synergistically mediate drought tolerance and BPH resistance through regulating cuticular wax and bulliform cells in rice, a new mechanism which might facilitate BPH resistance breeding.

Identification and analysis of brown planthopper-responsive microRNAs in the resistant and susceptible rice plants

Project description:MicroRNAs (miRNAs) regulate a spectrum of development and defense response processes in plants. The brown planthopper (BPH) is the most devastating insect pest of rice, BPH resistance gene BPH15 has a strong resistance to BPH. In this study, we analyzed six miRNA profiles of BPH15 introgression line (P15) and susceptible recipient line (PC) in 3 time points (0h, 6h and 48h) after BPH attacked, and identified 464 known miRNAs and 183 novel miRNAs. Before BPH feeding we identified 23 miRNAs expressed differently in P15 and PC. Then after BPH feeding, 104 miRNAs were found expressed differently in P15, and 80 miRNAs were found expressed differently in PC. Among them, miR167, miR444d, miR1846e, miR3979-3p, miR531 were found to be involved in BPH stress response. The response to BPH of P15 was much wider and more rapidly than PC. The levels of a subset of miRNAs were confirmed by qRT-PCR. The targets of miRNAs were predicted and validated by gene expression profiling. Additionally, the target genes of 2 differently expressed miRNAs (miR160f-5p and miR167a-5p) were confirmed by detecting YFP fluorescence and western blotting. Our data provide an important basis for evaluating the role of miRNA in the regulation of BPH interactions in rice.

Expression data from rice after brown planthopper attack

Project description:The aim of this study was to analyze potential brown planthopper (BPH) resistant genes in Rathu Heenati (RHT) by Affymetrix whole rice genome array,BPH susceptible and resistant rice varieties of TN1（Taichung Native 1）as control. All the resistant related genes derived from RHT will be analyzed according to the SSR markers interval flanked on the chromosome 3, 4, 6 and 10. It will be benefit to the gene clone and marker assistant breeding for Bph3 gene in the near future. We used microarrays to detail the global differential gene expression before and after brown planthopper attack in two different varieties, and identified distinct classes of high enriched genes induced by BPH or constituent in RHT The 2nd to 3rd instar nymphs of BPH were transferred to tillering stage seedings (10 BPH nymphs per plant) in a box covered with nylon-mesh. Stems of the rice plant infected by BPH were collected at 0h (T0), 8h (T8), 24h (T24) after BPH attack, total RNA were extracted for the microarray hybirdlization.

Rice plants infested with planthoppers

Project description:Infestation with white-backed planthopper (WBPH) to rice caused induced resistance to rice pathogens but brown planthopper (BPH) infestation induce weaker resistance to rice pathogens. We compared changes in gene expression in rice plants infested with WBPH and BPH to gain some insight into the WBPH-induced resistance to rice pathogens. An analysis, using microarrays, of gene expression in rice plants infested with these planthoppers revealed that WBPH infestation caused high induction of many defense-related genes including pathogenesis-related (PR) genes than BPH infestation. Furthermore, hydroperoxide lyase 2 (OsHPL2) which is an enzyme to produce C6 volatiles was induced by WBPH infestation, but not by BPH infestation. Keywords: response to herbivory; induced resistance

Expression data from BPH resistant and susceptible rice varieties

Project description:BPH9 is a gene that confers rice strong resistance to its devastating pest BPH. Understanding the molecular responses of the resistant and susceptible varieties would pave the way to controlling the pest more effectively. To better understand the molecular mechanism underlying resistance to BPH mediated by BPH9, we conducted a genome-wide microarray analysis of NIL-BPH9 and 9311 at the early stage of BPH infestation.
