Xenogamy and Current Obesity Pandemics

open access: yesOpen Journal of Genetics, 2011
This article unites the results from an integrative reconsideration of actual data about obesity from the viewpoint of recent developments in general pathology, epidemiology, immunology, genetics, and evolution. The focus is on the origin of genetic diversity in obesity manifestations on different levels of the disease.

Functions of hereditary immunity and xenogamy in cancer origin and pandemic spread

open access: yesOpen Journal of Immunology, 2011
The efficacy of means exploited currently for cancer prevention and treatment appeared to be very low. New insights into the origin of the disease are sorely needed. The present article synthesizes the results from integrative reconsideration of actual data on cancer from the viewpoint of recent developments in pathology, epidemiology, immunology ...

The Mating System of the Wild-to-Domesticated Complex of Gossypium hirsutum L. Is Mixed

open access: yesFrontiers in Plant Science, 2018
The domestication syndrome of many plants includes changes in their mating systems. The evolution of the latter is shaped by ecological and genetic factors that are particular to an area.

Towards a better understanding of the relationships between pollinators, human well‐being, and medicine plants in the Great Lakes Region of Eastern North America

open access: yesPLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 842-851, November 2023., 2023
A diversity of values is needed to maximize the effectiveness of conservation planning, including policies and programs. The results of the United Nations Biodiversity Conference (COP 15) in Montreal, Canada, highlight the importance of a shift towards recognizing multiple ways of knowing in ecology and conservation.

Pollination mode and reproductive system of Sanguisorba minor and Sanguisorba officinalis

open access: yesPlant Species Biology, Volume 38, Issue 4, Page 171-179, July 2023., 2023
Within one plant clade, often species with different pollination modes (e.g., wind and insect pollination) exist. We investigate the pollination and reproductive strategies of Sanguisorba minor and Sanguisorba officinalis and document remarkable differences between the two species.

Simultaneous movement of style and stamen set during anthesis in Etlingera elatior (Zingiberaceae) [PDF]

open access: yesRodriguésia, 2023
Etlingera is a genus of the family Zingiberaceae that is native to tropical Asia. Many species are economically important as a source of food, spices, medicines, and ornamental plants. This study aims to elucidate the floral morphology of E.

Beyond pollen:ovule ratios: Evolutionary consequences of pollinator dependence and pollination efficiency for pollen and ovule production in angiosperms

open access: yesAmerican Journal of Botany, Volume 110, Issue 6, June 2023., 2023
Abstract Premise The relative per‐flower production of ovules and pollen varies broadly with angiosperm mating systems, with outcrossing types commonly producing more pollen grains per ovule than selfing types. The evolutionary causes of this variation are contentious, especially the relevance of pollination risk.

Reproductive biology of the biofuel plant Jatropha curcas in its center of origin [PDF]

open access: yesPeerJ, 2016
In this work, we studied the main characteristics of flowering, reproductive system and diversity of pollinators for the biofuel plant Jatropha curcas (L.) in a site of tropical southeastern Mexico, within its center of origin. The plants were monoecious

Strong conservatism of floral morphology during the rapid diversification of the genus Helianthemum

open access: yesAmerican Journal of Botany, Volume 110, Issue 5, May 2023., 2023
Abstract Premise Divergence of floral morphology and breeding systems are often expected to be linked to angiosperm diversification and environmental niche divergence. However, available evidence for such relationships is not generalizable due to different taxonomic, geographical and time scales.

Is there a hybridization barrier between Gentiana lutea color morphs? [PDF]

open access: yesPeerJ, 2015
In Gentiana lutea two varieties are described: G. lutea var. aurantiaca with orange corolla colors and G. lutea var. lutea with yellow corolla colors. Both color varieties co-occur in NW Spain, and pollinators select flower color in this species.
