Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Floral biological investigations of apple cultivars in relation to fire blight
Floral activity was studied in two apple cultivars: an Erwinia-tolerant (Treedorn') and a sensitive one (`Sampion'). Since more types of protogyny occur in apples, the period of stigma activity is different.

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 ...

The Floral C-Lineage Genes Trigger Nectary Development in Petunia and Arabidopsis[OPEN]
C-lineage genes trigger nectary development in both petunia and Arabidopsis, despite their distant phylogeny, different nectary positioning, and different evolutionary trajectories.

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

Homologs of the STYLISH gene family control nectary development in Aquilegia.
Floral nectaries are an interesting example of a convergent trait in flowering plants, and are associated with the diversification of numerous angiosperm lineages, including the adaptive radiation of the New World Aquilegia species. However, we know very

1170. Allium kollmannianum Brullo, Pavone & Salmeri
Summary Allium kollmannianum is a small, late‐spring to early‐summer blooming Allium, endemic to the Negev Desert in south Israel, and previously thought to be extremely rare and critically endangered. Here we expand new information regarding its distribution and habitat in the Negev Desert, and a new estimation of its threat level, considering the new

Nectar is the main reward that flowers offer to pollinators to entice repeated visitation. Cucurbita pepo (squash) is an excellent model for studying nectar biology, as it has large nectaries that produce large volumes of nectar relative to most other ...

Nectary structure and nectar secretion of Echium russicum J. F. Gmel. flowers
In this study, the micromorphology of nectaries in Echium russicum J. F. Gmel. flowers was determined by using scanning electron microscopy (SEM) and their anatomy by using light microscopy (LM).

1173. Ipomoea pandurata (L.) G. Mey
Summary Ipomoea pandurata is a Morning Glory from North America which develops a large storage root. There is much uncertainty about its discovery before its formal description in the middle of the 18th century. Originally described as a Convolvulus, almost a hundred years passed before its recognition as a species of Ipomoea.
