| Abstract | ||
| The endospore forming bacterium, Pasteuria penetrans, is a hyperparasite of the root-knot nematodes, Meloidogyne spp. Which are economically important pest on a wide range of agricultural crops. The life cycle of both organisms is discussed and emphases are given to the potential of this bacterium to be successful biological control agents. The development of Pasteuria as a commercial biocontrol agent is faced with two obstacles, its inability to grow in vitro outside its host and its high host specificity. While the in vitro vegetative growth of the bacterium has been possible, getting this growth to sporulate has been difficult. Recent advances in nucleotide sequences, search of genomes, understanding the role of cation concentration in growth medium and the phosphorelation pathway of sporulation enzymes have proved useful. Genomic data has also provides useful information to understand the attachment mechanism of endospores to the nematode cuticle which revealed the involvement of the interaction between the collagen-like fibers on endospore surface and the mucins on the nematode cuticle . These findings can be utilized in biological control of plant nematodes and to draw the attention of the bio control specialist in the Arab countries to this important bacterium and prospect for future research in this field. | ||
