Abstract

Bu derlemede, bitki- fungus etkileşimini takiben hastalık gelişimi ve hastalık gelişiminde rol oynayan fungal virulans faktörleri özetlenmiştir. Tanımlanan
fungus türlerinin yaklaşık %10’ u 10,000’ den fazla bitkide hastalıklara neden
olmaktadır. Bu şekilde funguslar bitkilerde ciddi anlamda ekonomik kayıplara
neden olurlar. Bitki patojeni funguslar enfeksiyon şekilleri, enfeksiyon
yapısının farklılaşması ve işlevleri ve beslenme stratejileri açısından büyük
farklılıklar göstermektedirler. Bitki, patojen fungus saldırılarına karşı yaşamını devam ettirebilmek adına bir tanıma mekanizması ve zamanında ve etkili
bir şekilde bir savunma cevabı oluşturmaktadır. Bitki patojenik fungusların virulansı, birlikte çalışan ve infeksiyonu ortak tarzda oluşturan çok sayıda parametrenin sonucudur.

Virulence Factors in Plant Pathogen Fungi

Abstract

In this review, disease development following plant-fungus interaction and fungal virulence factors that play a role in disease development and are summarized. Approximately 10% of the identified fungus species cause diseases over 10,000 plants. In this way fungi cause serious economic losses in plants. Plant pathogenic fungi show great differences in terms of infection patterns, differentiation and function of infection structure and nutrition strategies. The plant forms a recognition mechanism and a defense response in a timely and effective manner in order to survive against pathogenic fungus attacks. The virulence of plant pathogenic fungi is the result of numerous parameters that work together and make the infection common.
