Abstract

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.

Keywords

Arabidopsis thaliana, Peronospora parasitica, hastalıklara dayanıklılık, mutant bitkiler
