Knock-in of exogenous sequences based on CRISPR/Cas9 targeting autosomal genes and sex chromosomes in the diamondback moth,Plutella xylostella

Genetic pest control strategies based on precise sex separation and only releasing sterile males can be accomplished by site-specific genome editing. In the current study, we showed that the mutation of single-allele Pxfl(2)d can significantly impair the normal mating behavior and testis development in male adults of the notorious cruciferous insect pest Plutella xylostella, in addition to its known functions in the ovarian development in female adults and egg hatching. Subsequent CRISPR/Cas9-based knock-in experiments revealed that site-specific integration of an exogenous green fluorescent protein(GFP) gene into autosomal Pxfl(2)d for labelling mutants could be achieved. However, this gene is not a suitable target for GFP insertion to establish a genetically stable knock-in strain because of the severe decline in reproductive capacity. We further screened for the W-chromosomelinked and Z-chromosome-linked regions to test the knock-in efficiency mediated by CRISPR/Cas9. The results verified that both types of chromosomes can be targeted for the site-specific insertion of exogenous sequences. We ultimately obtained a homozygous knock-in strain with the integration of both Cas9 and cyan fluorescent protein(CFP) expression cassettes on a Z-linked region in P. xylostella, which can also be used for early sex detection. By injecting the sgRNA targeting Pxfl(2)d alone into the eggs laid by female adults of the Z-Cas9-CFP strain, the gene editing efficiency reached 29.73%, confirming the success of expressing a functional Cas9 gene. Taken together, we demonstrated the feasibility of the knock-in of an exogenous gene to different genomic regions in P. xylostella, while the establishment of a heritable strain required the positioning of appropriate sites. This study provides an important working basis and technical support for further developing genetic strategies for insect pest control.

The scale-dependent predictability of the devastating 7·20 extreme rainstorm in Zhengzhou,china in 2021 was investigated via ensemble experiments,which were perturbed on different scales using the stochastic kinetic-energy backscatter(SKEB)scheme in the WRF model,with the innermost domain having a 3-km grid *** daily rainfall(RAIN24h)and the cloudburst during 1600-1700 LST(RAIN1h)were *** demonstrated that with larger perturbation scales,the ensemble spread for the rainfall maximum widens and rainfall forecasts become closer to the *** ensembles with mesoscale or convective-scale perturbations,RAIN1h loses predictability at scales smaller than 20 km and RAIN24h is predictable for all *** in ensembles with synoptic-scale perturbations,the largest scale of predictability loss extends to 60 km for both RAIN1h and ***,the average positional error in forecasting the heaviest rainfall for RAIN24h(RAIN1h)was 400 km(50-60)*** southerly low-level jet near Zhengzhou was assumed to be directly responsible for the forecast uncertainty of *** rapid intensification in low-level cyclonic vorticity,mid-level divergence,and upward motion concomitant with the jet dynamically facilitated the *** analysis of the divergent,rotational and vertical kinetic spectra and the corresponding error spectra showed that the error kinetic energy at smaller scales grows faster than that at larger scales and saturates more quickly in all ***-scale perturbations not only boost larger-scale error growth but are also conducive to error growth at all scales through a downscale cascade,which indicates that improving the accuracy of larger-scale flow forecast may discernibly contributes to the forecast of cloudburst intensity and position.
