Perianth bilateral symmetry (zygomorphy) has evolved repeatedly from radial symmetry (actinomorphy) throughout angiosperms. Zygomorphy has previously been linked with plant‐pollinator specialization and higher species diversification. However, the exact number of transitions to and from zygomorphy has remained so far unknown. We recorded perianth symmetry from 761 species, selected to represent all 61 orders and 426 currently accepted families of angiosperms and to include all presumed origins of perianth zygomorphy. We then reconstructed the evolution of perianth symmetry on a consensus backbone tree, using parsimony. We found perianth zygomorphy in 32 orders and 110 families. There was a minimum of 130 origins, almost double of what was previously estimated, and 69 reversals to actinomorphy. Among the origins, 2 were in magnoliids, 29 in monocots, 17 in basal eudicots, 35 in superrosids and 47 in superasterids. Among the reversals, 8 were in monocots, 4 in basal eudicots, 18 in superrosids and 39 in superasterids. This study shows that there has been many more origins of perianth zygomorphy and reversals to actinomorphy than previously shown. We then use this new framework to review the developmental evidence of changes in floral symmetry, showing convergence in the early stages of zygomorphy across angiosperms at the developmental level. We also review the evidence on the genetic control of floral symmetry, suggesting that a restricted number of genes has been recruited multiple times independently to achieve zygomorphy. In contrast to its relative homogeneity at the early developmental and molecular level, zygomorphy appears to be highly variable in its morphological expression at anthesis, involving various processes such as perianth part displacement and differentiation. We then review recent hypotheses on the relationship between floral symmetry, floral orientation, and pollination mode in terms of selective advantages and constraints. Our comprehensive angiosperm‐wide reconstruction of floral symmetry evolution provides a new context for future studies on the developmental, functional, and macroevolutionary aspects of floral symmetry.

Paulownia tomentosa, a member of the plant family Paulowniaceae and a rich source of biologically active secondary metabolites, is traditionally used in Chinese herbal medicine. Flavonoids, lignans, phenolic glycosides, quinones, terpenoids, glycerides, phenolic acids, and miscellaneous other compounds have been isolated from different parts of P. tomentosa plant. Recent interest in this species has focused on isolating and identifying of prenylated flavonoids, that exhibit potent antioxidant, antibacterial, and antiphlogistic activities and inhibit severe acute respiratory syndrome coronavirus papain-like protease. They show cytotoxic activity against various human cancer cell lines and inhibit the effects of human cholinesterase, butyrylcholinesterase, and bacterial neuraminidases. Most of the compounds considered here have never been isolated from any other species of plant. This review summarizes the information about the isolated compounds that are active, their bioactivities, and the structure-activity relationships that have been worked out for them. major flavonoid of citrus, activity reviewed by Khan and Zill-E-Huma (2014) 114 R1= R2= R3=R4= H 121 R1= R2=R3=R4 = H 115 R1= OH (6S), R2= R3=R4= H 122 R1= OH (6S), R2=R3= R4= H 116 R1= R3=R4= H, R2= OH (7R) 123 R1= R3=R4= H, R2= OH (7R) 117 R1= R2=R4= H, R3= OH (8R) 124 R1= R2=R4= H, R3= OH (8R) 118 R1= R2=R3= H, R4= OH (9R) 125 R1= R2=R3= H, R4= OH (9R) 119 R1= R3=R4= H, R2= OAc (7R) 126 R1= R2=R4= H, R3= OAc (8R) 120 R1= R2=R4= H, R3= OAc (8R) 127 R1= R2=R3= H, R4= OAc (9R)

“…The Paulownia genus was previously categorized as part of the Scrophulariaceae family, but now, it has now been categorized as a monotypic family of its own, Paulowniaceae, based on the latest molecular phylogenetic data (Erbar and Gülden 2011). Now, only nine species are accepted as part of the Paulownia genus by Flora of China as shown in Table 1 (Chinese Flora Editorial Committee 1998).…”

Paulownia C-geranylated flavonoids: their structural variety, biological activity and application prospects

et al. 2019

View full text Add to dashboard Cite

Paulownia species, especially their flowers and fruits, are traditionally used in Chinese herbal medicines for the treatment of infectious diseases. Cgeranylated flavonoids were found to be the major special metabolites in Paulownia flowers and fruits, and 76 C-geranylated flavonoids had been isolated and characterized thus far. Structural variations in Paulownia C-geranylated flavonoids are mainly due to the complicated structural modifications in their geranyl substituents. These natural compounds have attracted much attention because of their various biological activities, including antioxidation, antiinflammation, cytotoxic activity and various enzymatic inhibitions, etc. Among them, diplacone, a major Paulownia component, was considered to have promise for applications in medicine. This paper summarizes the information from current publications on Paulownia C-geranylated flavonoids, with a focus on their structural variety, key spectroscopic characteristics, biological activity with structureactivity relationships and application prospects. We hope that this paper will stimulate further investigations of Paulownia species and this kind of natural product.
