Protocol
Sample Preparation of Arabidopsis thaliana Shoot Apices for Expression Studies of Photoperiod-Induced Genes
Plants produce new organs from a population of pluripotent cells which are located in specific tissues called meristems. One of these meristems, the shoot apical meristem (SAM), gives rise to leaves during the...

PEP1 regulates perennial flowering in Arabis alpina
Most studies on the regulation of flowering have been performed in annuals such as the classic 'lab plant' Arabidopsis thaliana, which flower only once in their lifetime. Much less work has been done on the poten...

An epigenetic mutation responsible for natural variation in floral symmetry
Although there have been many molecular studies of morphological mutants generated in the laboratory, it is unclear how these are related to mutants in natural populations, where the constraints of natural sel...

Origin of floral asymmetry in Antirrhinum
Dorsoventral asymmetry in flowers is thought to have evolved many times from a radially symmetrical ancestral condition. The first gene controlling floral asymmetry, cycloidea in Antirrhinum, has been isolated. T...

Control of inflorescence architecture in Antirrhinum
Flowering plants exhibit two types of inflorescence architecture: determinate and indeterminate. The centroradialis mutation causes the normally indeterminate inflorescence of Antirrhinum to terminate in a flower...
