Abstract

Fungal patojenler bitkilerde ciddi hastalıklara yol açarak tüm dünyada ekonomik
kayıplara neden olurlar. Bu hastalıkların çoğu böcekler ve fungal patojenler tarafından
kaynaklanmaktadır. Kitin doğada en bol bulunan biyopolimerlerdendir. Bazı bitkiler
tarafından üretilen kitinaz enzimi tarafından katalize edilerek yıkılabilirler. Kitinazlar fungusların
hücre duvarının parçalanmasını sağladıkları için bitki savunmasında önemli bir rol
oynadığı düşünülmektedir. Kitinazların çoğu in vitro şartlar altında fungal patojenlerin
gelişmesini engellemektedirler. Bu derlemede fungal patojenlere karşı dayanıklı bitkilerin
geliştirilmesi açısından kitinazların özellikleri sunulmuştur.

Keywords
