Etilena merupakan suatu gas pertumbuhan yang telibat dalam beragam proses seluler, perkembangan dan proses terkait stress pada tanaman. Sejumlah peran yang dimainkan oleh etilena contohnya penentuan jenis kelamin bunga, induksi bunga, pemanjangan tunas dan pengurangan daun. Kemajuan terbaru tentang pemahaman mekanisme molekuler yang mendukung pasca-penyerbukan pada proses layunya bunga anggrek telah dilakukan pengujian. Studi ini menunjukkan bahwa proses bunga anggrek menjadi layu pasca penyerbukan melibatkan sensitivitas awal terhadap kadar etilena endogen yang berperan menggerakan proses dimana etilena secara autokatalitik menginduksi sintesisnya sendiri dalam putik. Konsep yang diambil dari proses ini kemudian diterapkan pada episermis akar arabidopis dimana etilena mempunyai peran pentig dalam perkembangan rambut akar. Memahami konsep molekuler tentang peran etilena dalam model ini akan memberikan manfaat yang berguna untuk mengetahui bagian yangh dimainkan oleh etilena dalam beragam proses yang melibatkan faktor pertumbuhan.
