The 3′ untranslated region of a rice α-amylase gene functions as a sugar-dependent mRNA stability determinant

Abstract: In plants, sugar feedback regulation provides a mechanism for control of carbohydrate allocation and utilization among tissues and organs. The sugar repression of ␣-amylase gene expression in rice provides an ideal model for studying the mechanism of sugar feedback regulation. We have shown previously that sugar repression of ␣-amylase gene expression in rice suspension cells involves control of both transcription rate and mRNA stability. The ␣-amylase mRNA is significantly more stable in sucrose-starved cells… Show more

“…In cold-soaking-tolerant cultivars, a certain level of AmyI-1 expression might remain regardless of germination status. The expression of both AmyII-3 and AmyII-4 is precisely regulated by sugars (Huang et al, 1990;Chan and Yu, 1998;Mitsui et al, 1999;Nanjo et al, 2004b;Chen et al, 2006). However, in the present study, these expression patterns in non-germinated seeds were different (Table 2).…”

“…The results confirm AtSUC9 expression in flowers and siliques, suggesting that there are additional regulatory elements outside the 5# region. Regulatory elements outside the 5# region are well documented (Taylor, 1997); for example, AGAMOUS (Deyholos and Sieburth, 2000), rice (Oryza sativa) a-amylase (Chan and Yu, 1998), and a-fetoprotein (Scohy et al, 2000) are plant genes with intragenic regulatory elements. Additionally, AtSUC1 also shows differential expression patterns when comparing whole-geneTGUS to promoterTGUS.…”

“…A plausible mechanism for AtTZF1 to control gene expression is via posttranscriptional regulation, an area that has not been addressed widely in plant sugar signaling. For example, the mRNA halflife of rice a-amylase gene is affected by sugar via destabilization signal sequences at the 3# UTR (Chan and Yu, 1998). Furthermore, the 3# UTR of the maize cell wall invertase gene Incw1 is likely to affect sugardependent mRNA metabolism and translation (Cheng et al, 1999).…”
