Seed ferns experimented with complex leaf vein networks 201 million years ago, paleontologists find

According to a research team led by paleontologists from the University of Vienna, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several ...

Flowers may be more ancient than dinosaurs, but scientists can't agree on when they evolved

Flowers may look delicate—but flowering plants, what scientists call angiosperms, are one of the most successful evolutionary organisms on the planet. Including more than 350,000 known species, they dominate the ecological ...

Botanists analyze the role of pollinators in the evolution of flowers with various sexual forms

Researchers Violeta Simón, Marcial Escudero and Juan Arroyo, from the Department of Botany at the Faculty of Biology of the University of Seville, in collaboration with researchers from four other countries, led a study ...

How flowers maintain water balance across different angiosperm branches

Flowers play an essential role in maintaining a species' genetic stability. Understanding how flowers regulate water use strategies to adapt to their environment is crucial for better understanding floral evolution and plant-pollinator-environment ...

Research team reveals cellular and molecular basis of spur development in Impatiens uliginosa

As an important reproductive organ of angiosperms, flowers have a clear purpose and adaptive significance in their various characteristics. As a typical floral evolutionary feature, the floral spur is a tubular structure ...

Understanding jasmonic acid: A switch that activates autophagy in Arabidopsis petals

Organogenesis, an important aspect of flowering, helps reveal key processes of plant development such as the formation of floral organs, attainment of reproductive capability, and abscission leading to seed and fruit development.

Genome database for desiccation-tolerant plants released

Desiccation is typically fatal for plant vegetative tissues, but a small number of land plants have evolved vegetative desiccation tolerance (VDT), allowing them to dry without dying through a process called anhydrobiosis.

Chinese scientists reveal novel mechanism of angiosperm self-incompatibility

Self-incompatibility (SI) is a widespread intraspecific reproductive barrier in flowering plants, a system for rejecting self-pollen to prevent seed set after self-pollination. In Solanaceae, Plantaginaceae, Rosaceae, and ...

Researchers reinvestigate phylogenetic and biogeographic history of trees in Cryptocaryeae

The family Lauraceae is a prominent component of the evergreen broadleaf forests in the tropics and subtropics. However, the biogeographical history of the family is poorly understood due to the difficulty of assigning macrofossils ...
