Bitki Savunma Sistemlerinde Hormonal Sinyal Moleküller ve Çapraz İletişimleri

Öz

Bitkiler oldukça kompleks olan savunma sistemleri sayesinde patojen atağını algılar, sınırlandırır ve karşı atağa geçebilirler. Bitki savunma sistemlerinin aktive olabilmesi için reseptörlerden bitki hücresi genomuna sinyal transdüksiyonun olması gereklidir. Bu yolda savunma sistemini tetikleyen salisilik asit (SA), jasmonik asit (JA) ve etilen (ET) gibi hormonal sinyal moleküllerin varlığı ve bitkide tüm savunma tepkilerini koordine eden karmaşık bir sinyal ağının bulunduğu kanıtlanmıştır. Bu sinyallerin etkileşimi, bitkinin hem lokal hem de sistemik olarak, doğru savunma tepkilerini oluşturmasını sağlamaktadır.
