A particularly virulent O149:H10 enterotoxigenic Escherichia coli clone harbours a newly characterized plasmid pTENT2 carrying the tetracycline-resistance tetA and the virulence genes estA, paa, and sepA that were not present in less virulent clones. The objectives of this study were to assess whether the additional genes on pTENT2 played a role in the increased severity of post-weaning diarrho...

Alzheimer's disease (AD) is a progressive and irreversible neurodegenerative disease causing neural cell degeneration and brain atrophy and is considered to be the most common form of dementia. We previously generated an induced pluripotent stem cell (iPSC) line from an AD patient carrying an A79V mutation in PSEN1 as an in vitro disease model. Here we generated a gene-corrected version from th...

Bacterial leaf pustule (BLP) disease is caused by Xanthomonas axonopodis pv. glycines (Xag). To investigate the plant basal defence mechanisms induced in response to Xag, differential gene expression in near-isogenic lines (NILs) of BLP-susceptible and BLP-resistant soybean was analysed by RNA-Seq. Of a total of 46 367 genes that were mapped to soybean genome reference sequences, 1978 and 783 g...

Total flower and pod numbers (TFPN) effective per plant (PNPP) are among the most important agronomic traits for soybean production. However, underlying genetic mechanism remains unclear. In this study, we constructed a recombinant inbred line population derived from cross between JY73 (high TFPN) TJSLH (low to map loci two traits. total, six QTL TFPN five PNPP were identified, which on chromos...

Abstract Future agricultural systems will need to become more resilient as climate change impacts increase. One expected outcome of is an increase in severe thunderstorms with high velocity straight line winds. In August 2020, a derecho, cluster generating high‐speed prolonged‐duration winds, swept through Iowa and Illinois the north central U.S. Corn Belt. Damage estimates from derecho range u...

In Arabidopsis recombinant inbred line (RIL) populations are widely used for quantitative trait locus (QTL) analyses. However, mapping analyses with this type of population can be limited because of the masking effects of major QTL and epistatic interactions of multiple QTL. An alternative type of immortal experimental population commonly used in plant species are sets of introgression lines. H...

Brown planthopper (BPH) has become the most devastating insect pests of rice and a serious threat to production. To combat newly occurring virulent BPH populations, it is still urgent explore more new broad-spectrum resistance genes integrate them into cultivars. In present study, we explored genetic basis in IRGC 8678. We identified mapped gene Bph43 region ~380 kb on chromosome 11. Genes enco...
