Polyploidization plays an important role in plant speciation. The most recent estimates report that up to 15% of angiosperm speciation events and 31% in ferns are accompanied by changes in ploidy level. Polyploids can arise either through autopolyploidy, when the sets of chromosomes originate from a single species, or through allopolyploidy, when they originate from different species. In this s...

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 ...

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...

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...

The experiment was conducted in the Ecology Field, Arid Forest Research Institute, Jodhpur (Rajasthan), India during 2020-21 to explore role of insect pollinators fruit setting P. cineraria. For conducting experiments one branches selected trees covered with a mesh bags exclude floral visitors (pollinator exclusion). other branch kept uncovered for time (open pollination). Our findings revealed...

In this paper, a crude methanolic extract from the stem bark of Prosopis cineraria, a plant native of Pakistan, was tested for its possible presence of spasmolytic, bronchodilator, and vasodilator activities in an attempt to validate some of its folkloric uses. Moreover, attempts were made to provide plausible explanations of the observed biological activities. The extract caused relaxation of ...

Lectins are comprised of a large family of proteins capable of the specific and reversible recognition of carbohydrates. Legume lectins, the most studied plant lectins, show high structural similarity, but with modifications that imply a variation in the intensity of some biological activities. In this work, the primary and tertiary structures of Canavalia grandiflora (ConGF) were determined. C...

In the Bateson-Dobzhansky-Muller model of genetic incompatibilities post-zygotic gene-flow barriers arise by fixation of novel alleles at interacting loci in separated populations. Many such incompatibilities are polymorphic in plants, implying an important role for genetic drift or balancing selection in their origin and evolution. Here we show that NPR1 and RPP5 loci cause a genetic incompati...
