Plant Biology: Seedling Emergence through Soil

Curr Biol. 2016 Jan 25;26(2):R68-R70. doi: 10.1016/j.cub.2015.12.003.

Abstract

The resistance encountered by a seedling as it pushes through the soil causes inhibition of stem elongation and stimulates stem thickening, facilitating soil penetration. A new study demonstrates that two proteolytic pathways work in double-negative fashion - one targeting the other - to protect transcription factors central to this response.
