Genome-wide identification of SULTR genes in tea plant and analysis of their expression in response to sulfur and selenium

Integrative Transcriptome and Proteome Analysis Reveals the Absorption and Metabolism of Selenium in Tea Plants [Camellia sinensis (L.) O. Kuntze]

“…Plants absorb selenate and selenite via sulfate and phosphate transporters, respectively. Tea and other plants have four different types of sulfate transporters ( Gigolashvili and Kopriva, 2014 ; Zhang et al, 2021 ). In Arabidopsis thaliana , SULTR1;1 and SULTR1;2 are high-affinity sulfate transporters that absorb selenate.…”

Genome-Wide Identification of Sultr Genes in Malus domestica and Low Sulfur-Induced MhSultr3;1a to Increase Cysteine-Improving Growth

“…Sulfate transporters are encoded by multiple gene families (Gigolashvili and Kopriva, 2014), and 8-28 gene members have been identified in Arabidopsis, rice, maize, and soybeans (Takahashi et al, 2000;Kumar et al, 2011;Ding et al, 2016;Huang et al, 2018). In this study, a total of nine MdSultr genes were identified in M. domestica, all of which were structurally characterized by the presence of a highly conserved Sulfate_transp domain and STAS domains (Figures 2B,C and Supplementary Table 5), as described in other species such as sorghum, potatoes, and tea trees (Vatansever et al, 2016;Akbudak et al, 2018;Zhang et al, 2021), indicating that MdSultrs have the typical characteristics of Sultrs. In addition, the phylogenetic tree analysis separated them into two distinct groups, such that MdSultr4;2 and the remaining MdSultrs were on Group 4 and 3, respectively (Figure 1B).…”

“…generally divided into four subfamilies. About 8 CsSultrs in the tea plant are also classified into four groups (Zhang et al, 2021). Interestingly, studies in tea plants, corn, and wheat have shown that some genes in Group 1 and 3 are highly homologous and similar in function (Buchner et al, 2010;Huang et al, 2018;Zhang et al, 2021).…”

“…Interestingly, studies in tea plants, corn, and wheat have shown that some genes in Group 1 and 3 are highly homologous and similar in function (Buchner et al, 2010;Huang et al, 2018;Zhang et al, 2021). For example, PtaSultr3;3a and PtaSultr1;1 in poplar are responsible for SO 2− 4 loading into the phloem (Dürr et al, 2010), and CsSultr1;1, CsSultr1;2, and CsSultr 3;2 in tea plants were significantly induced by an exogenous S treatment (Zhang et al, 2021). Similarly, ZmSultr1;1, ZmSultr1;2, and ZmSultr3;4 were upregulated in S-deficient maize roots (Huang et al, 2018).…”

“…To date, previous studies have mainly focused on model plants and field crops, while only a few studies have reported on horticultural crops (Takahashi, 2019). Studies in horticultural crops have been limited to the identification of 12 BSultr members in Brassica oleracea (Buchner et al, 2004a), 8 CsSultr genes in tea plants that are involved in the response to selenium (Zhang et al, 2021), and 18 PtaSultrs in poplar trees that regulate the distribution of SO 2− 4 in the phloem at the transcriptional level (Dürr et al, 2010). Although some Sultr members have been identified in horticultural crops, relatively few Sultrs have been functionally characterized, and the basic knowledge of Sultrs in apples has not yet been reported.…”
