Control of axillary bud initiation and shoot architecture in Arabidopsis through the SUPERSHOOT gene

Article Abstract:

The SUPERSHOOT gene has been found to control Arabidopsis axillary bud initiation and shoot architecture. The control has been studied in a mutant, supershoot (sps), which has huge overproliferation of shoots. One plant can generate 500 or more inflorescences. As SPS gene encodes a cytrochrome P450, a role in modulating hormone levels can be seen, given a 3- to 9-fold increase in levels of Z-type cytokinins in sps mutant plants.

Localization of the auxin permease AUX1 suggests two functionally distinct hormone transport pathways operate in the Arabidopsis root apex

Article Abstract:

Research has been conducted on the plant hormone auxin which regulates plant development. The localization of the auxin permease AUX1 in the Arabidopsis root apex has been carried out and the results indicate the existence of phloem-based indole-3-acetic acid transport pathway.

The SPOROCYTELESS gene of Arabidopsis is required for initiation of sporogenesis and encodes a novel nuclear protein

Article Abstract:

The SPOROCYTELESS (SPL) gene of the flowering plant Arabidopsis thaliana, necessary for sporogenesis initiation and encoding a novel nuclear protein, is discussed. The SPL mutation analysis suggested that development of the anther walls and tapetum and mcrosporocyte formation are closely involved and that nucellar development may depend on megasporocyte formation.
