Around 470 million years ago, plants began to conquer the terrestrial surfaces. The first examples had a small axis terminated by a structure capable of forming spores, almost like current mosses. The ...

Plant reproductive complexity increased in two, widely separated pulses likely driven by important evolutionary innovations, including the origin of seeds and flowers, according to a new study. These ...

Plant reproductive development, spanning flowering, pollination, fertilization, and seed formation, is orchestrated through the integration of genetic, epigenetic, hormonal, and environmental cues.

Penn researchers and colleagues have discovered how plants respond to seasonal flowering cues while protecting the stem cells at their growing tip, enabling continuous reproduction in changing ...

Researchers have shed light on the reproductive role of 'dark matter' DNA - non-coding DNA sequences that previously seemed to have no function. Their findings have revealed that a specific non-coding ...
