The plant hormone ethylene
Webb18 okt. 2024 · In angiosperms, the plant hormone ethylene is known to play a protective role in responses to abiotic stress. Here we investigated whether ethylene mediates resistance to abiotic stress in the liverwort Marchantia polymorpha, one of the most distant land plant relatives of angiosperms. Webb22 dec. 2015 · To tightly control this association and keep it mutualistic, the plant uses several means, including hormones. The hormone ethylene has been known as a negative regulator of nodulation for almost four decades. Since then, much progress has been made in the understanding of both the ethylene signaling pathway and the nodulation process.
