Cellular Ultrastructure and Crystal Development in Amorphophallus (Araceae)

Cellular ultrastructure and crystal development in Amorphophallus (Araceae).

BACKGROUND AND AIMS Species of Araceae accumulate calcium oxalate in the form of characteristically grooved needle-shaped raphide crystals and multi-crystal druses. This study focuses on the distribution and development of raphides and druses during leaf growth in ten species of Amorphophallus (Araceae) in order to determine the crystal macropatterns and the underlying ultrastructural features ...

Isolation and characterization of microsatellite loci for the herbaceous tuber crop, Amorphophallus konjac (Araceae).

Amorphophallus konjac is an herbaceous tuber crop with tremendous potential for commercial development. We report the development of microsatellite primers for this important crop species. Thirteen polymorphic microsatellite markers were developed and tested in two populations of A. konjac from the Wuling Mountain Region (WL population) and the Yunnan Province (YN population) in China. The numb...

Genetic variation in wild populations of the tuber crop Amorphophallus konjac (Araceae) in central China as revealed by AFLP markers.

Amorphophallus konjac is an economically important crop. In order to provide baseline information for sustainable development and conservation of the wild plant resources of A. konjac, we studied the genetic diversity and population structure of this species using amplified fragment length polymorphism (AFLP) molecular markers. We sampled 139 individuals from 10 wild populations of A. konjac in...

Pollen Wall Ultrastructure of Araceae and Lemnaceae in Relation to Molecular Classifications

A comparative ultrastructural study of Araceae pollen walls was conducted for the first time. The results are based mainly on investigations by transmission electron microscopy of 101 species in 70 genera (out of a total of 105 genera), while pollen of 83 genera with 219 species were studied by scanning electron microscopy, generally without acetolysis. Special attention was given to Lemnaceae ...
