Angiosperms - Anatomy & histology
Research News and Information
Definition of 'Angiosperms'Any member of the more than 250,000 species of flowering plants. Angiosperms are often differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Common names: Angiosperms; Magnoliophyta |

The earliest normal flower from Liaoning Province, China.
30 Jul 2009 
The early evolution of angiosperms has been a focus of intensive research for more than a century. The Yixian Formation in western Liaoning yields one of the earliest angiosperm macrofloras. Despite multitudes of angiosperm fossils uncovered, ... Read more...
Micropreparation of single secretory glands from the carnivorous plant Nepenthes.
10 Jul 2009 A rapid mechanical micropreparation technique has been developed to isolate multicellular glands, here from Nepenthes pitchers, based on a microdissection platform. The method is an alternative to laser capture dissection because fresh plant tissue ... Read more...
24 Jun 2009 Flowers exhibit adaptive responses to biotic and abiotic factors. It remains unclear whether pollen susceptibility to rain damage plays a role in the evolution of floral form. We investigated flower performance in rain and compared pollen longevity ... Read more...
