Natural phytochemicals and their derivatives are good drug candidates for anticancer therapeutic approaches against multiple targets. We report here the initial findings from our studies on the anticancer properties of the leaves of the medicinal plant Sesbania grandiflora. In the current study, five different solvent fractions from the leaves of S. grandiflora were tested on cancer cell lines ...

Peat use in horticulture continues to be scrutinized as consumers are becoming increasingly aware of the environmental sustainability concerns associated with peat. Thus, horticultural industry is driven search for peat alternatives. Substrate stratification (i.e., vertical layering unique media atop another a singular container) has been studied nursery substrates and demonstrated improved res...

BACKGROUND Tomato spotted wilt virus (TSWV) has a very wide host range, and is transmitted in a persistent manner by several species of thrips. These characteristics make this virus difficult to control. We show here that the over-expression of the mitochondrial alternative oxidase (AOX) in tomato and petunia is related to TSWV resistance. RESULTS The open reading frame and full-length sequen...

The transition to selfing in Capsella rubella accompanies its recent divergence from the ancestral outcrossing C. grandiflora species about 100,000 years ago. Whether the change in mating system was accompanied by the evolution of additional reproductive barriers that enforced species divergence remained unknown. Here, we show that C. rubella and C. grandiflora are reproductively separated by a...

BACKGROUND Duabanga grandiflora or known in Malaysia as Berembang Bukit, Megawasih, or Pedada Bukit, is a native plant of the Southeast Asian countries. In this study, the anti-viral properties of D. grandiflora were investigated. METHODS The D. grandiflora leaf extracts were obtained with ethyl acetate, hexane, and ethanol as solvents and labelled 37 leaf ethyl acetate (37 L EA), 37 leaf hex...

Flower cultures are represented by Gauston ageratum, double-feathered cosmea, erect marigolds thin-leaved marigolds, hybrid petunia brilliant sage. Closed-ground crops cucumber, tomato, hot pepper Bulgarian pepper; open-ground seed peas, radish, garlic, potatoes, sorr...

Nitric Oxide (NO) can autoregulate its own formation by feedback inhibition of the inducible Nitric Oxide Synthase (iNOS). Modulation of biosynthesis or activity of NO results in amelioration if pathogenesis of experimental arthritis. However, little is known about feedback mechanism on NO generation in response to carrageenan induced paw oedema and adjuvantinduced arthritis. In the present stu...

In vivo stable isotope labeling and computer-assisted metabolic flux analysis were used to investigate the metabolic pathways in petunia (Petunia hybrida) cv Mitchell leading from Phe to benzenoid compounds, a process that requires the shortening of the side chain by a C(2) unit. Deuterium-labeled Phe ((2)H(5)-Phe) was supplied to excised petunia petals. The intracellular pools of benzenoid/phe...

Autophagy is one of the main mechanisms of degradation and remobilization of macromolecules, and it appears to play an important role in petal senescence. However, little is known about the regulatory mechanisms of autophagy in petal senescence. Autophagic processes were observed by electron microscopy and monodansylcadaverine staining of senescing petals of petunia (Petunia hybrida); autophagy...

Petunia, which has been prevalently cultivated in landscaping, is a dicotyledonous herbaceous flower of high ornamental value. Annually, there is a massive worldwide market demand for petunia seeds. The normal development of anther is the necessary prerequisite for the plants to generate seeds. However, the knowledge of petunia anther development processes is still limited. To better understand...
