Laodelphax striatellus


The small brown planthopper, Laodelphax striatellus, is one of the most destructive agricultural pests worldwide. It feeds on gramineous plants including rice. Apart from feeding damage, L. striatellus transmits various plant viruses, such as Rice stripe virus, Rice black-streaked dwarf virus, and so on. L. striatellus is distinct from another two rice planthoppers, Sogatella furcifera and Nilaparvata lugens, in host range, dispersal capacity, and vectoring plant viruses. The genome sequences of S. furcifera and N. lugens have been revealed recently. Deciphering the genome of L. striatellus would provide an unprecedented chance to explore the genetic basis for these biological differences among the three rice planthoppers through comparative genomic analysis.

A total of 193 Gb Illumina data and 32.4 Gb Pacbio data were generated to assemble a 541 Mb of genome with a contig N50 of 118 Kb and a scaffold N50 of 1.08 Mb, representing 98% of the estiated genome size (550 Mb by k-mer analysis). Repetitive elements comprised 25.7% of the genome assembly. Combined annotation strategies predicted a set of 17736 protein-coding genes, capturing 97.6% and 98% of BUSCO eukaryote and arthropoda genes, respectively. Addtionaly 80% of protein-coding geneswere functionally annotated. In all, we reported a high quality of genome of L. striatellus.
