Fertilization in angiosperms depends on a complex cellular "courtship" between haploid pollen and diploid pistil. These pollen-pistil interactions are regulated by a diversity of molecules, many of which remain to be identified and characterized. Thus, it is unclear to what extent these processes are conserved among angiosperms, a fact confounded by limited sampling across taxa. Here, we report...

The essential oil of Chrysanthemum coronarium flowerheads showed strong nematicidal activity in vitro and in growthchamber experiments. Essential oil concentrations of 2, 4, 8 and 16 μL mL, significantly reduced hatch, J2 survival (determined by final value and area under curves of cumulative percentage hatch or mortality) and reproduction rate of Meloidogyne artiellia in vitro, with the lowest...

Considering the importance of natural products in cancer therapy, a preliminary investigation on some anticancer medicinal plants of north-eastern states of India was conducted in murine tumor model. Nine different plants such as Ageratum conizoides Linn. (Asteraceae), Blumea lanceolaria Linn. (Asteraceae), Dillenia pentagyna Roxb. (Dilleniaceae), Potentilla fulgens Wall. (Rosaceae), Taxus bacc...

Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi....

Inceer, H. (2021). Lectotypification of two Boissier's names in Chamaemelum (Anthemideae, Asteraceae). Candollea 76: 259–260. In English, English abstract. Turkey appears to be a center diversity for the genus Tripleurospermum Sch. Bip. Asteraceae) with c. 32 species among 40 accepted genus. Two conoclinium Boiss. & Balansa and monticola A. Huet are lectotypified discussed. Received: May 5, 202...

The current investigations suggest the segregation of Jurinea cartilaginea from Jurinea, and its placement among Centaureinae. Molecular studies, based on the nuclear ribosomal internal transcribed spacers (nrITS), chromosome number data and pollen morphology, support the morphological results. Based on these results, J. cartilaginea is related to and, therefore, transferred to the genus Karvan...

Plants from Asteraceae family are widely used as herbal medicines and food ingredients, especially in Asian area. Therefore, authentication and quality control of these different Asteraceae plants are important for ensuring consumers' safety and efficacy. In recent decades, electronic nose (E-nose) has been studied as an alternative approach. In this paper, we aim to develop a novel discriminat...

New combinations are provided in Distephanus for two species from Madagascar.
