Petunia flower petals emit large amounts of isoeugenol, which has been shown to be synthesized by isoeugenol synthase (PhIGS1) from an ester of coniferyl alcohol, hypothesized to be coniferyl acetate. This paper describes the identification and characterization of a novel petunia gene encoding an enzyme belonging to the BAHD acyltransferase family whose expression correlates with isoeugenol bio...

The present study was aimed to evaluate the phytochemical constituents and antibacterial activity of the flower extracts of Albizia lebbeck, Cordia sebestena, Thunbergia grandiflora and Antigonon leptopus. Preliminary phytochemical screening was done by the standard methods described by Harborne. Antibacterial study was carried out by disc diffusion method. The results of the phytochemical anti...

Beaumontia grandiflora Wall. (Apocynaceae) is an ornamental plant cultivated in Egypt. Investigation of the chemical constituents of the aerial parts of B. grandiflora Wall. in pet. ether extract led to isolation and identification of twelve fatty acids in which linoleic acid (29.60%) and Palmitic acid (19.12%) are the main acids. The unsaponifiable fraction was found to contain a series 14 27 ...

Franklinia alatamahaBartr. exMarshall represents amonotypic genus that was originally discovered in Georgia, USA, but is now considered extinct in the wild and is maintained only in cultivation. Although Franklinia is very ornamental, with showy flowers and crimson/maroon fall foliage, it tends to be short lived when grown as a landscape tree and is known to be susceptible to a variety of root ...

The comparative chromosomal features of four species belonging to family Apocynaceae from Northeastern Thailand were studied the root tips. somatic chromosome numbers all specimens found be 2n = 36 for Allamanda blanchetii, 18 A. cathartica, 20 in schottii and 52 Cryptostegia grandiflora. cathartica have same number previous except C. grandiflora differs previously reported. Moreover, has never...
