Abstract

Histological studies of brinjal roots inoculated with Meloidogyne javanica, two or three weeks before Pseudomonas solanacearum biotype-3 inoculation showed extensive cavities of broken cortical and endodermal cells. The nematode inoculated roots contained pronounced hyperplastic and hypertrophic regions characterised by ‘giant cells’ with dense cytoplasm and enlarged nuclei. The cellular changes (hypertrophy and hyperplasia) resulted in syncytial formation. Development in the nematode inoculated roots predisposed the bacterial invasion and colonization.
