“…Soluble protein content in glyphosate-treated corollas did not cause any significant changes. Glyphosate caused a reduction of anthocyanin formation and PAL activity (Shimada and Kimura, 2006) but did not affect the aromatic amino acid and protein biosynthesis. Phenylalanine and tyrosine are the important precursors in the production of phenolic compounds and lignin (Duke et al, 1979).…”

A change of flower shape was observed in petunia corollas treated with 0.5 mm glyphosate. Glyphosate changed the flower symmetry from the actinomorphic type to the zygomorphic type. Corollas treated with glyphosate showed an increased free amino acid content. Free amino acid profiles in petunia corollas revealed that glyphosate had no significant effect on aromatic amino acid levels but increased the level of proline. Soluble protein content in glyphosate-treated corollas did not cause any significant changes. The contents of soluble phenolics, lignin, and IAA in the corollas were not significantly affected by the glyphosate treatment. In contrast, glyphosate reduced the nitrate content and the RNA content of petunia corollas by 45% and 63% of the control, respectively. However, the DNA content in glyphosate-treated corollas was similar to that of the control.Low concentrations of glyphosate did not show any phytotoxic effects on the whole plants and any remarkable changes on aromatic amino acid metabolism and protein synthesis. However, glyphosate reduced the RNA content of petunia corollas and changed the flower symmetry from the actinomorphic type to the zygomorphic type. The results of nonprotein nitrogen metabolism in glyphosate-treated petunia corollas suggested that glyphosate application at low concentration may influence the regulation of flower symmetry through the change of RNA biosynthesis.

“…This study uses a technique of applying glyphosate (N-phosphonomethylglycine) (Jaworski, 1972) to petunia flower buds for characterizing the metabolism related to the flower shape. Application of glyphosate reveals the change of petunia flower shape from the actinomorphic type to the zygomorphic type (Shimada and Kimura, 2006).…”

“…At present, few studies have explored the influence of CYC -like genes on flower development in the Solanaceae . Petunia hybrida is an annual herb that produces solitary flowers in leaf axils [ 134 ]. Its funnel-shaped corolla is white or purple and may be variously striped.…”

CYCLOIDEA (CYC)-like genes belong to the TCP transcription factor family and play important roles associated with flower development. The CYC-like genes in the CYC1, CYC2, and CYC3 clades resulted from gene duplication events. The CYC2 clade includes the largest number of members that are crucial regulators of floral symmetry. To date, studies on CYC-like genes have mainly focused on plants with actinomorphic and zygomorphic flowers, including Fabaceae, Asteraceae, Scrophulariaceae, and Gesneriaceae species and the effects of CYC-like gene duplication events and diverse spatiotemporal expression patterns on flower development. The CYC-like genes generally affect petal morphological characteristics and stamen development, as well as stem and leaf growth, flower differentiation and development, and branching in most angiosperms. As the relevant research scope has expanded, studies have increasingly focused on the molecular mechanisms regulating CYC-like genes with different functions related to flower development and the phylogenetic relationships among these genes. We summarize the status of research on the CYC-like genes in angiosperms, such as the limited research conducted on CYC1 and CYC3 clade members, the necessity to functionally characterize the CYC-like genes in more plant groups, the need for investigation of the regulatory elements upstream of CYC-like genes, and exploration of the phylogenetic relationships and expression of CYC-like genes with new techniques and methods. This review provides theoretical guidance and ideas for future research on CYC-like genes.
