Partial screening of collagenolytic and proteolytic activity of vesicular arbuscular mycorrhiza

Abstract
Mycorrhizza has the symbiotic association between plant roots and fungal mycelium. This fungus helps solubilize phosphorus and bring soil nutrients (phosphorous nitrogen, micronutrients and water) into the plant in exchange for carbon. Interestingly, VAM also reduces the number of root knot-nematode infestation. However, there have been no studies regarding the mechanisms on how nematode populations are inhibited in the presence of VAM fungi. Collagen is the main component of nematode cuticle and helps in the movement and imparts some longitudinal elasticity. The collagenolytic activity exhibited by VAMRI showed comparable activity with commercial collagenase. Degradation of collagen was evident as the substrate became thinner and obscured. Moreover, a higher proteolytuc activity was obtained for VAMRI compared to other treatments. In conclusions, the data suggests that VAM fungi produce collagenase and protease which the authors assume might effect nematode species found in plants.
