J. Mol. Sci. 2021, 22,four ofproteins (Table two). One example is, OsSUT1 is critical for rice improvement in the reproductive development stage, and OsSUT1 shows the strongest expression among rice SUT genes, especially within the stem plus the establishing caryopsis. The expression of OsSUT2 is weaker than that of OsSUT1 but stronger than that of the remaining SUT genes of rice. Accordingly, the abnormality of OsSUT2 mutants is milder than that of OsSUT1 mutants but higher than that from the remaining rice SUT gene knockout mutants. In addition, the expressions of rice SUT genes, specifically OsSUT1 and OsSUT2, focus around the leaf, stem, and grain (Table two). These organs are the supply, transport, and sink organs of rice, respectively. Notably, all SUT genes except for OsSUT2 show pretty weak expressions in the root at the transcriptional level. Xu et al. [53] reported that none with the rice SUT genes were expressed inside the root, as detected through GUS expression. However, yet another investigation employing the identical process showed that OsSUT1 was expressed within the root of rice shortly just after seed germination [34]. Unique promoter lengths applied for driving GUS expression or various observation instances probably gave rise to these variations.Table 2.

Hyphenated and numbered genes denote various transcripts.Interestingly, Arabidopsis possesses nine SUC members, although the rice SUT household includes five SUT members, despite the fact that the Arabidopsis genome is only about one-third of your rice genome [21,41,42]. Having said that, both Arabidopsis and rice contain 12 SUT gene transcripts based on a recent investigation [34]. Notably, OsSUT1 possesses at the least six option splicings of transcripts [34]. As option splicing is actually a way to regulate plant development [54], it possibly explains why rice SUTs can assume so many roles in plant growth and development with limited members. Nevertheless, functional characterizations of all transcripts of OsSUT1 and elucidating their regulation mechanisms remain difficult. three. Rice SUT Gene Regulations Not surprisingly, the ex.
