Characterization of one of the targets of this translation regulatory machinery,
the ethylene signaling component EBF2, indicates that the signaling molecule EIN2 and the nonsensemediated decay proteins UPFs play a central role in this ethylene - induced translational response.
On the other hand, fertilization of the egg cell strongly activates
ethylene signaling, which also induces selective disorganization of the nucleus in the persistent synergid cell.
Thus, the persistent synergid cell completely loses its pollen tube attracting function by synergetic SE fusion and
ethylene signaling.
The researchers show that, when ethylene is perceived, transcription of certain genes that function as circuit breakers of
ethylene signaling occurs, but protein production becomes restricted until ethylene is removed.
Meanwhile, fertilisation of the egg cell activates its «
ethylene signalling» pathway, which degrades the nucleus of the persistent synergid cell.

Specifically, the paper shows that a key
signaling molecule, EIN2, is an essential component in the
ethylene - response process.
Signals from other molecules can sometimes fall at nearby frequencies, in effect smudging the
ethylene glycol fingerprint.
Using the well - characterized
signaling pathway of the phytohormone
ethylene and plant - optimized genome - wide ribosome footprinting, we have uncovered a molecular mechanism linking this hormone's perception to the activation of a gene - specific translational control mechanism.
