Suppression of heterotrimeric G-protein beta-subunit affects anther shape, pollen development and inflorescence architecture in tobacco

The role of the heterotrimeric G-protein β-subunit in plant development was studied in transgenic tobacco (Nicotiana tabacum L.) plants with reduced β-subunit levels due to the antisense expression of the β-subunit mRNA. The antisense plants had aberrant anther shape and produced non-germinating pol...
