Hormona peptídica vegetal

Les hormones peptídiques vegetals són un grup de fitohormones peptídiques.

El senyalament peptídic té un paper significatiu en diversos aspectes del creixement i desenvolupament de les plantes i s'han identificat receptors espècífics per a diversos pèptids tenint el paper quinases receptores localitzades en les membranes. Els pèptids senyalitzadors inclouen membres de les següents famílies de proteïnes:

Sistemina — funciona com a senyal a llarga distància contra els danys provocats pels herbívors.^[1]

Família pèptida CLV3/ESR —^[2]

ENOD40 — un gen nodulina.^[3]^[4]^[5]^[6]
Fitosulfoquina (PSK) —.^[7]^[8]

POLARIS (PLS) —.^[9]

Factor d'alcalinització ràpida (RALF) —^[10]

SCR/SP11 —.^[11]^[12]^[13]
ROTUNDIFOLIA4/DEVIL1 (ROT4/DVL1) —.^[14]^[15]

Deficient inflorescència en abscisió (IDA) —.^[16]
