Widely targeted metabolomic profiling combined with transcriptome analysis provides new insights into amino acid biosynthesis in green and red pepper fruits

Comprehensive study on nutritional, flavour and metabolite characteristics of green prickly ash (Zanthoxylum schinifolium) at different picking stages

“…Amino acid is the basic unit of protein, which plays an important role in the nutrition and taste of Z. schinifolium (Fei et al ., 2022). The amino acid composition and content of Z. schinifolium at different picking stages are shown in Table S2.…”

“…On the basis of colour, prickly ash is classified into red prickly ash ( Zanthoxylum bungeanum ) and green prickly ash ( Zanthoxylum schinifolium ) (Ni et al ., 2022). At present, a large number of studies have been carried out on Z. bungeanum (Fei et al ., 2022; Wang et al ., 2022). However, detailed and comprehensive research on nutritional and flavour properties for Z. schinifolium are limited, which largely limits the development of industry.…”

Metabolomics and Transcriptomics Analyses Reveal Regulatory Networks Associated with Fatty Acid Accumulation in Pecan Kernels

“…Zhang et al demonstrated that flavonoids, particularly anthocyanins, were the major components that modulated jujube peel reddening and further obtained three UDP-glucose flavonoid 3-O-glucosyltransferase genes implicated in the extensive accumulation of anthocyanins . Moreover, similar studies were performed in Lycium ruthenicum , L. barbarum , Actinidia arguta , bamboo, and pepper . Nevertheless, the dynamic changes in metabolomics during pecan nut development and its molecular regulation mechanisms are yet to be reported.…”

“…23 Moreover, similar studies were performed in Lycium ruthenicum, L. barbarum, 29 Actinidia arguta, 30 bamboo, 31 and pepper. 28 Nevertheless, the dynamic changes in metabolomics during pecan nut development and its molecular regulation mechanisms are yet to be reported.…”

“…In pecans, untargeted metabolomics has been performed to study scab resistance between resistant and susceptible varieties and determine whether quercetin derivatives may be important metabolites for scab resistance . In addition, combining metabolomics with transcriptomics has become a viable strategy to identify the molecular basis behind the biosynthesis of various nutrients. ,,− Tan et al integrated the analysis of metabolomics and transcriptomics to delineate lipid biosynthesis and associated transcriptional regulation in developing Brassica napus embryos . Wang et al investigated the changing patterns of antioxidant components during kernel development and identified several key genes associated with phenylpropane metabolism .…”
