    Fenglan Zhao1, Jizhi Jin1, Meng Yang1, Franklin Eduardo Melo Santiago2, Jianping Xue1, Li Xu3,*, Yongbo Duan1,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.3, pp. 611-625, 2024, DOI:10.32604/phyton.2024.048295

    Abstract

    Seed germination with selenium (Se) is promising for producing Se-biofortified foods. Mungbean (Vigna radiata (L.) Wilczek) sprout is freshly eaten as a salad dressed with sauce, making it superior for Se biofortification. Since the Se safety range for the human body is extremely narrow, it is imperative to evaluate the genotypic responses of mungbean sprouts to Se. This study evaluated the Se enrichment capacity and interaction with flavonoids and antioxidant systems in sprouts of 20 mungbean germplasms. Selenium treatment was done by immersing mungbean seeds in 20 μM sodium selenite solution for 8 h. Afterward, the

    Abstract Tree peony cultivars with yellow flowers are rare and valuable, but the molecular mechanism of pigment accumulation is not clear. In this study, the petal transcriptome of three developmental stages were sequenced to determine the differentially expressed genes (DEGs) regulating yellow flowers color. The results showed that 10,842 and 12,022 DEGs were screened in stage 1 vs. stage 2 and in stage 2 vs. stage 3, respectively. Through analysis of flavonoid structural genes (FSGs), we found that the transcription level of DFR was very low in the three developmental stages. In a small group of cultivars, the… More >
