Floral longevity, nectar production, pollen release, and stigma receptivity in Haskap (Lonicera caerulea)

Journal of Pollination Ecology, 2016
Haskap (Lonicera caerulea L.) is a temperate fruiting shrub grown commercially in northern regions of Europe, Asia, and North America. Haskap is self-incompatible and requires insect pollinators in order to set fruit; however, very little is currently ...

Ambivalence at the Helm: How the Positive Effect of Ambivalence to Lead on Leader Integrative Complexity Affects Leaders' Effectiveness

Journal of Organizational Behavior, EarlyView.
ABSTRACT We study the phenomenon of ambivalence to lead, characterized as leaders' experience of mixed feelings (positive and negative) toward their leadership position. We do so by integrating the beneficial role of dualities with the affect‐as‐information theory.

Evaluation of Promising Characteristics of Rhizomatous Alfalfa Male Sterile Mutant Accessions

Agronomy
Evaluating key traits of male sterile mutant accessions in rhizomatous alfalfa (Medicago sativa L.) is crucial for selecting plants for artificial hybrid breeding of rhizomatous maternal lines. In this study, branch cuttings from four male sterile mutant

Study on pollen viability and stigma receptivity throughout the flowering period in the selected taxa of the Gesneriaceae family

Folia Horticulturae, 2023
Plants in the Gesneriaceae family are appreciated for their decorative leaves and flowers, ease of cultivation, and shade tolerance. Sexual hybridisation has long been carried out for producing novel hybrids.

In Utero HSC Transplantation for Sickle Cell Disease: A Potential Therapeutic Approach That Overcomes Complications of Current Therapies

Prenatal Diagnosis, EarlyView.
ABSTRACT Sickle cell disease (SCD) affects millions worldwide but has limited treatment options, most of which carry significant side effects. At present, the only curative treatment for SCD is allogeneic or gene‐modified autologous hematopoietic stem cell (HSC) transplantation (Tx).

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...
