Pistil Development Delay Limits Seed Set in Protandrous Onion (Allium cepa L.)

Agronomy
Onion (Allium cepa L.) plants produce umbellate inflorescences that bear dozens of hermaphrodite flowers. Outcrossing is encouraged by a strong protandrous dichogamy.

Asynchronous Synchronization: A Spatially Explicit Agent-Based Model Simulating <i>Ficus</i> Trees and Their Obligate Wasp Pollinator. [PDF]

Ecol Evol
Normal or baseline scenario with parameterization from the literature. The green line indicates the CPS based on the decision tree. The blue hatched area indicates the transition period of the model where there are increasing number of wasps present at the end of the simulations and an indication that the model is becoming more stable.

Anthecology of some species of Hamanthus Bunge and Halimocnemis C.A. Mey [PDF]

BIO Web of Conferences, 2023
It is promising to grow the long-vegetating annual halophytes Gamanthus Bunge and Halimocnemis C.A. Mey. (Chenopodiaceae Vent.) in arid locations since they are important grazing plants for Karakol sheep and camels. These species’ xerothermic periods are

Flower color polymorphism in the peacock anemone (Anemone pavonina) reflects spatiotemporal variation in pollinator abundance. [PDF]

Am J Bot
Abstract Premise Flower color polymorphisms are found across angiosperms and are shaped by multiple environmental factors. We investigated Anemone pavonina, which displays flower color variation from red to purple along an elevational gradient on Mount Olympus, Greece.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Cleomaceae: diversity and potential of a model family for studies on the evolution of photosynthesis. [PDF]

Plant Biol (Stuttg)
The Cleomaceae family integrates floral diversity, physiological plasticity, and the evolution of C4 photosynthesis, serving as an important model to investigate plant adaptation and evolutionary innovation. Abstract Understanding the physiological and molecular mechanisms by which plants adapt to environmental factors is essential for improving crop ...

Mechanical stimulation of the stigmas triggers switch from female to male phase in the protogynous trap flower of Aristolochia rotunda (Aristolochiaceae)

Mediterranean Botany, 2023
Floral longevity is a selected trait that shows plasticity, allowing plants to balance resource allocation and reproduction. In dichogamous flowers—in which female and male functions are decoupled in time—the duration of the female phase is expected to ...

A Global Analysis of the Distribution Patterns of Style-Length Polymorphisms Across Angiosperms. [PDF]

Ecol Evol
This study tested the tropicality‐ and diversity‐driven hypotheses to explain the global distribution of style‐length polymorphisms (SLP) in angiosperms. Phylogenetic logistic regression revealed that although SLP occurrence was associated with tropical regions, this pattern was driven by the predominantly tropical family Rubiaceae and disappeared once
