In China,19%of agricultural soils contain harmful heavy metal pollutants at levels exceeding environmentally recommended standards,whilst around 3 million hectares of arable land are too polluted to grow crops on(Zhao et al.,2015;Hu et al.,2016).Among the deleterious heavy metals,cadmium(Cd)is the most bioavailable toxic metallic pollutant and is rapidly transferable through the food chain(Wang et al.,2019).Concerning the current dilemma of the enhanced food demands of a rising population and decreasing availability of arable land,it is promising to cultivate field crops that produce enough safe foods for human consumption and simultaneously remove the pollutants from contaminated arable lands.

采用高效液相色谱—串联质谱(UHPLC–MS/MS)技术对西瓜5份具有代表性的材料果实进行代谢产物分析,在此基础上选取栽培西瓜高糖材料‘97103’和野生西瓜低糖材料‘PI296341’,利用气相色谱—质谱联用(GC–MS)方法对主代谢产物进行定量分析。从成熟果实中定量鉴定出58种代谢物,其中22种在‘97103’和‘PI296341’间存在显著差异。韧皮部运输的棉籽糖在野生低糖材料果实中大量滞留,而在栽培高糖材料中极少积累。综合差异代谢物及其代谢途径分析发现,高糖材料‘97103’果实在水苏糖、棉籽糖等光合产物卸载途径及蔗糖积累代谢途径上的代谢产物积累较高;而低糖材料‘PI296341’,则在氨基酸代谢、有机酸代谢途径及6–磷酸葡萄糖等糖代谢途径上产物积累较高。这些发现为野生西瓜进化到栽培种果实品质的代谢产物积累和调控提供了重要依据,也可为提高西瓜品质提供指导。

Qingke (Tibetan hulless barley) has long been cultivated and exposed to long-term and strong UV-B radiation on the Tibetan Plateau, which renders it an ideal species for elucidating novel UV-B responsive mechanisms in plants. Here we report a comprehensive metabolite profiling and metabolite-based genome-wide association study (mGWAS) using 196 diverse qingke and barley accessions. Our results demonstrated both constitutive and induced accumulation, and common genetic regulation, of metabolites from different branches of the phenylpropanoid pathway that are involved in UV-B protection. A total of 90 significant mGWAS loci for these metabolites were identified in barley-qingke differentiation regions, and a number of high-level metabolite trait alleles were found to be significantly enriched in qingke, suggesting co-selection of various phenylpropanoids. Upon dissecting the entire phenylpropanoid pathway, we identified some key determinants controlling natural variation of phenylpropanoid content, including three novel proteins, a flavone C-pentosyltransferase, a tyramine hydroxycinnamoyl acyltransferase, and a MYB transcription factor. Our study, furthermore, demonstrated co-selection of both constitutive and induced phenylpropanoids for UV-B protection in qingke.

rice(Oryza sativa L)is one of the most important crops world-wide,providing much of the calorific needs for half of the global population[1].Due to the development of the global economy and the improvement of living standards,people's demand for rice has gradually changed from"being fll"to"eating well",with tasty and nutritious varieties being essential for the *** the past few decades,lots of studies have focused on improving the eating and cooking quality(ECQ)of rice to meet the demand for taste[2].Although metabolic engineering has been applied in rice biofortif-cation in recent years[3.4],efforts on improving comprehensive nutrition in rice remain fragmented[5-7].Thus,characterizing QTLs and genes underlying nutrient abundance will provide new guidance for breeding varieties with health benefits.
