“…The B. cinerea isolate (20160401PB) was obtained from tree peony flower buds in a plastic-covered greenhouse in the Sui and Tang dynasties city ruins botanical garden, located in Luoyang, Henan Province, China. The pathogenic fungus was isolated and purified via usual tissue isolation methods (Fang, 1998) and then the isolate was cultured on a potato dextrose agar (PDA) plate medium to observe colony morphology (Tian et al, 2019). After sporulation, the morphological characteristics were observed, photomicrographs of conidiophores and conidia were obtained, and conidia size was measured.…”

Gray mold caused by Botrytis cinerea has become an important limiting factor for tree peony production. Currently, chemical control is still the main means of managing the disease in China. The objective of this study was to test fungicides with different mechanisms of action in controlling B. cinerea on tree peony. The inhibitory efficacy of five fungicides on four asexual stages was measured in the petri dish containing culture medium amended with a tested fungicide at various concentrations. The results showed that carbendazim had the strongest inhibition effect against all four stages of B. cinerea, with the EC50 values of 0.1037, 0.0563, 0.5578, and 0.0797 mg·L–1, respectively. The inhibitory effect of diethofencarb was only slightly less than that of carbendazim on conidia production, germination, and germ tube elongation. The inhibitory effect of procymidone was second only to that of carbendazim on colony expansion. The results indicated that carbendazim and diethofencarb could be used as protective fungicides to spray in the early stage of disease occurrence to inhibit conidia germination and germ tube elongation, so as to reduce the infection rate of B. cinerea and prevent disease occurrence. Carbendazim, procymidone, and diethofencarb mainly inhibit the reinfection of B. cinerea by inhibiting the growth of mycelium and the production of conidia, so they could be used as control fungicides during the occurrence phase of the disease.

“…The reason is that the P. capsici has strong adaptability to fungicides and new hosts plants [1–6] . Fungicide is still an effective way to control P. capsici because the research on resistant germplasm resources lags behind the evolution of pathogens [5–9] . Like other members of this destructive genus, P. capsici has strong infectivity, a wide host and high resistance frequency [1–6] .…”

Endeavor to discover biorational natural products‐based fungicides, two series (26) of novel 1‐sulfonyloxy/acyloxydihydroeugenol derivatives (3a–p and 5a–j) were prepared and assessed for their fungicidal activity against P. capsici Leonian, in vitro. Results of fungicidal activity revealed that, among all compounds, especially compounds 3a, 5c, and 5e displayed the most potent anti‐oomycete activity against P. capsici with EC50 values of 69.33, 68.81, and 67.77 mg/L, respectively. Overall, the anti‐oomycete activities of 1‐acyloxydihydroeugenol derivatives (5a–j) were higher than that of 1‐sulfonyloxydihydroeugenol derivatives (3a–p). It is proved that the introduction of the acyl group at hydroxy position of dihydroeugenol is more beneficial to improve its anti‐oomycete activity than that of the sulfonyl group. These preliminary results will pave the way for further modification of dihydroeugenol in the development of potential new fungicides.

“…Plants frequently suffer from various biotic and abiotic stresses which adversely affect plant growth and development [ 1 , 2 ], while transcription factor (TFs) are important regulators that involved in various biological and environmental stress processes [ 3 ]. Among them, zinc finger proteins (ZFPs) account for a relatively large family of eukaryotic transcription factors [ 4 ].…”

Backgrounds C2H2-type zinc finger protein (ZFPs) form a relatively large family of transcriptional regulators in plants, and play many roles in plant growth, development, and stress response. However, the comprehensive analysis of C2H2 ZFPs in cucumber ( CsZFPs ) and their regulation function in cucumber are still lacking. Results In the current study, the whole genome identification and characterization of CsZFPs , including the gene structure, genome localization, phylogenetic relationship, and gene expression were performed. Functional analysis of 4 selected genes by transient transformation were also conducted. A total of 129 full-length CsZFPs were identified, which could be classified into four groups according to the phylogenetic analysis. The 129 CsZFPs unequally distributed on 7 chromosomes. Promoter cis -element analysis showed that the CsZFPs might involve in the regulation of phytohormone and/or abiotic stress response, and 93 CsZFPs were predicted to be targeted by one to 20 miRNAs. Moreover, the subcellular localization analysis indicated that 10 tested CsZFPs located in the nucleus and the transcriptome profiling analysis of CsZFPs demonstrated that these genes are involved in root and floral development, pollination and fruit spine. Furthermore, the transient overexpression of Csa1G085390 and Csa7G071440 into Nicotiana benthamiana plants revealed that they could decrease and induce leave necrosis in response to pathogen attack, respectively, and they could enhance salt and drought stresses through the initial induction of H 2 O 2 . In addition, Csa4G642460 and Csa6G303740 could induce cell death after 5 days transformation. Conclusions The identification and function analysis of CsZFPs demonstrated that some key individual CsZFPs might play essential roles in response to biotic and abiotic stresses. These results could lay the foundation for understanding the role of CsZFPs in cucumber development for future genetic engineering studies.
