“…at anthesis to open the floret and is thus cleistogamous [111,112]. While the current evidence suggests that sugar importation into the lodicule is restricted in Cly1 plants, there is need for further histological and physiological investigation of sugar importation into Cly1 lodicules.…”

EuAP2 genes are famous for their role in flower development. A legacy of the founding member of this subfamily of transcription factors, whose mutants lacked petals in Arabidopsis. However, studies of euAP2 genes in several species have accumulated evidence highlighting the diverse roles of euAP2 genes in other aspects of plant development. Here, we emphasize other developmental roles of euAP2 genes in various species and suggest a shift from regarding euAP2 genes as just flowering genes to consider the global role they may be playing in plant development. We hypothesize that their almost universal expression profile and pleiotropic effects of their mutation suggest their involvement in fundamental plant development processes.

“…Cleistogamy1 (Cly1) (also known as HvAP2) encodes a miR172-resistant euAP2 gene and is therefore overexpressed. The lodicule differentiates fully in Cly1 plants but does not enlarge enough at anthesis to open the floret and is thus cleistogamous [113,114]. While current evidence suggests that sugar importation into the lodicule is restricted in Cly1 plants, there is need for further histological and physiological investigation of sugar importation into Cly1 lodicules.…”

“…In cereals like barley, wheat and rice a pair of lodicule lie below the carpel and swell at maturity, forcing the lemma and ovary apart, which results in open (chasmogamous) flowers at maturity. Over-expression of Cleistogamy 1 (Cly1), an euAP2 gene in barley has been shown to lead to cleistogamy [48,49]. In Cly1 mutants, the lodicule does not enlarge at maturity but remain small leaving the florets tightly closed.…”

miR172 downregulates the translation of cleistogamy 1 in barley

Abstract: Direct evidence is presented to show that miR172a acts to reduce the abundance of the CLY1 protein, which enables open flowering in barley.
