“…The sampling sites spanned the area south of the Huai River in China at latitude 8 • 52 and longitude 20 • 13 in southern China. The distance between samples was at least 100 m to avoid collecting clones [10,28].…”

“…In addition, the climate varies among geographical locations, and thus indirectly influences the phenotypes of L. cubeba. Previous studies have also linked environmental factors to fruit phenotypes and metabolites, particularly terpenoids [10,57,58]. For example, AAR was found to increase with latitude and longitude, and AAR affected the contents of volatile components and terpene compounds.…”

“…Because L. cubeba essential oil has a high economic value, it is highly sought after in domestic and international markets and has attracted the attention of researchers. In a recent survey of the germplasm resources of L. cubeba, we found rich phenotypic diversity and relatively low utilization rates [10,11].…”

“…Recent studies on L. cubeba have included ecological resource surveys [24], technical studies on seedling propagation [1], analyses of the antibacterial and antioxidant effects of essential oil [25], and the use of molecular biology methods to determine the mechanism of terpene metabolism with a view to improve terpenoid yield [26]. Relatively few studies have explored how geographical features, climatic conditions, and soil physicochemical properties affect traits such as the fruit yield (FY), essential oil content (EOC), and citral content of L. cubeba [10]. Breeding work using elite L. cubeba families has been carried out, but it is difficult to breed new varieties in a short period of time [27].…”

“…A few studies have explored how geographical features and climatic conditions affect traits such as FY, EOC, and citral content [14]. Fan et al (2023) [10] found that FY and EOC are greatly affected by the environment. They found that the EOC decreases and the citral content increases with increasing longitude.…”

Litsea cubeba (Lour.) Pers. is an important woody spice tree in southern China, and its fruit is a rich source of valuable essential oil. We surveyed and sampled L. cubeba germplasm resources from 36 provenances in nine Chinese provinces, and detected rich phenotypic diversity. The survey results showed that plants of SC-KJ, SC-HJ, and SC-LS provenance presented higher leaf area (LA); YN-SM and YN-XC plants had larger thousand-grain fresh weight (TFW); and HN-DX plants had the highest essential oil content (EOC). To explain the large differences in the phenotypes of L. cubeba among different habitats, we used Pearson’s correlation analysis, multiple stepwise regression path analysis, and redundancy analysis to evaluate the phenotypic diversity of L. cubeba. It was found that compared to other traits, leaf and fruit traits had more significant geographical distributions, and that leaf phenotypes were correlated to fruit phenotypes. The results showed that elevation, latitude, longitude, total soil porosity (SP), soil bulk density (SBD), and average annual rainfall (AAR, mm) contributed significantly to the phenotypic diversity of L. cubeba. Geographical factors explained a higher percentage of variation in phenotypic diversity than did soil factors and climate factors. Plants of SC-KJ and HN-DX provenances could be important resources for domestication and breeding to develop new high-yielding varieties of this woody aromatic plant. This study describes significant phenotypic differences in L. cubeba related to adaptation to different environments, and provides a theoretical basis for the development of a breeding strategy and for optimizing L. cubeba cultivation.

BACKGROUNDRice sheath blight caused by Rhizoctonia solani is a severe threat to the yield and quality of rice. Due to the unscientific abuse of common fungicides causing resistance and environmental issues, the development of new fungicides is necessary. In this study, we used citral as the lead compound, designed and synthesized a series of novel citral amide derivatives, and evaluated their antifungal activity and mode of action against R. solani.RESULTBioassay results indicated that antifungal activities of most citral amide derivatives against R. solani were significantly improved compared to citral, with EC50 values ranging from 9.50–27.12 mg/L. Among them, compound d21 containing the N‐(Pyridin‐4‐yl)carboxamide group exhibited in vitro and in vivo fungicidal activities, with curative effects at 500 mg/L as effectively as the commercial fungicide validamycin·bacillus. Furthermore, d21 prolonged lag phase of the growth curve of R. solani, reduced the amount of growth, and inhibited sclerotium germination and formation. Mechanistically, d21 deformed the mycelia, increased cell membrane permeability, and inhibited the activities of antioxidant and TCA‐related enzymes. Metabolome analysis showed the abundance of some energy‐related metabolites within R. solani increased, and simultaneously the antifungal substances secreted by itself reduced. Transcriptome analysis showed that most genes encoding ABC transporters and peroxisomes upregulated after the treatment of d21, and cell membrane destruction.CONCLUSIONThis study indicates that novel citral amide derivatives possess antifungal activity against R. solani and are expected to develop an alternative option for chemical control of rice sheath blight.This article is protected by copyright.
