Cellular and gene expression patterns associated with root bifurcation in Selaginella Universiteit Gent Vlaams Instituut voor Biotechnologie
The roots of lycophytes branch through dichotomy or bifurcation, during which the root apex splits into two daughter roots. This is morphologically distinct from lateral root (LR) branching in the extant euphyllophytes, with LRs developing along the root axis at different distances from the apex. Although the process of root bifurcation is poorly understood, such knowledge can be important, because it may represent an evolutionarily ancient ...
