Konukçu-Patojen İlişkisinde Model Bir Bitki: Arabidopsis thaliana

Öz

Arabidopsis thaliana (Arabidopsis)’nın kromozom sayısının az olması, bu bitkinin genetik yapısının diğer bitki türlerine göre daha kolay çalışılmasına olanak sağlamakta, ayrıca diğer bitkilerde patojenlere karşı gözlenen ana savunma mekanizmaları bu bitkide de bulunmaktadır. Bu açıdan, konukçu bitkilerin patojen saldırılarına karşı savunma mekanizmalarını çalışma konusunda Arabidopsis bitkisi ideal bir model sistem oluşturmaktadır. Bu derlemenin amacı, patojenlere karşı bitki savunma mekanizmasının genetiğini anlamada Arabidopsis’in bir şablon olarak nasıl kullanıldığını, bitki ekotiplerinin patojen izolatlarına karşı gösterdiği farklılıkları (duyarlılık ve dayanıklılık) ortaya koyacak inceleme metodlarını açıklamaktadır.

Anahtar Kelimeler
