Abstract ：
Copper-based antimicrobial compounds are widely and historically used to control plant diseases, such as late blight caused by Phytophthora infestans, which seriously affects the yield and quality of potato. We previously identified that copper ion (Cu2+) acts as an extremely sensitive elicitor to induce ethylene (ET)-dependent immunity in Arabidopsis. Here, we found that Cu2+ induces the defence response to P. infestans in potato. Cu2+ suppresses the transcription of the abscisic acid (ABA) biosynthetic genes StABA1 and StNCED1, resulting in decreased ABA content. Treatment with ABA or inhibitor fluridone made potato more susceptible or resistance to late blight, respectively. In addition, potato with knockdown of StABA1 or StNCED1 showed greater resistance to late blight, suggesting that ABA negatively regulates potato resistance to P. infestans. Cu2+ also promotes the rapid biosynthesis of ET. Potato plants treated with 1-aminocyclopropane-1-carboxylate showed enhanced resistance to late blight. Repressed expression of StEIN2 or StEIN3 resulted in enhanced transcription of StABA1 and StNCED1, accumulation of ABA and susceptibility to P. infestans. Consistently, StEIN3 directly binds to the promoter regions of StABA1 and StNCED1. Overall, we concluded that Cu2+ triggers the defence response to potato late blight by activating ET biosynthesis to inhibit the biosynthesis of ABA.

Abstract ：
Small RNAs (sRNAs), including microRNAs (miRNAs) and short interfering RNAs (siRNAs), are non-coding but powerful RNA molecules of 20-30 nucleotides in length. sRNAs play crucial regulatory roles in diverse plant biological processes. Recently, many studies on sRNAs have been reported. We summarize new findings of sRNAs in virus-plant interactions to accelerate the function analysis of sRNAs. The main content of this review article includes three parts: virus-responsive sRNAs, function analysis of sRNAs in virus pathogenicity or host resistance, and some sRNAs-mediated underlying mechanisms in virus-plant interactions. New findings of sRNAs deepen our understanding about sRNAs' roles, which might contribute to the design of novel control measures against plant viruses.

Abstract ：
Main conclusionA rice allele of PSKR1 functioning in resistance to bacterial leaf streak was identified.AbstractPhytosulfokine (PSK), a disulfated pentapeptide encoded by precursor genes that are ubiquitously present in higher plants, belongs to the group of plant peptide growth factors. The PSK receptor PSKR1 in Arabidopsis thaliana is an active kinase and has guanylate cyclase activity resulting in dual-signaling outputs. Here, the LOC_Os02g41890 out of three candidates completely rescued root growth and susceptible to Pseudomonas syringae pv. DC3000 in the Arabidopsis pskr1-3 mutant and was identified as OsPSKR1. This protein was localized to plasma membrane similar to AtPSKR1. The expression of OsPSKR1 was upregulated upon inoculation with RS105, a strain of Xanthomonas oryzae pv. oryzicola (Xoc) that cause bacterial leaf streak in rice. OsPSKR1 overexpression (OE) lines had greater resistance to RS105 than the wild type. Consistently, the expression of pathogenesis-related genes involved in the salicylic acid (SA) pathway was upregulated in the transgenic lines. Overall, OsPSKR1 functions as a candidate PSK receptor and regulates resistance to Xoc by activating the expression of pathogenesis-related genes involved in the SA pathway in rice.
