Abstract:
Mungbean dry root rot incited by Macrophomina phaseolina (Tassi.) Goid is the most destructive seed and soil borne disease which appears every year and causes heavy losses in yield. Present investigation was carried out in screenhouse pot condition for histopathology of mungbean plant roots (variety MH 318) inoculated with Glomus hoi (mycorrhiza) and M. phaseolina using microscopy. In the present study, three treatments inoculated with mycorrhiza, M. phaseolina and control plant roots were observed.
Among them mycorrhizal-inoculated roots, interwoven fungal mycelium, arbuscules and vesicles were observed within cortical cells, resulting in a compacted cortex, while these structures were absent in control roots. The pericycle, located beneath the endodermis and consisting of one to two cell layers, remained unaffected by mycorrhizal colonization. The vascular bundles, containing xylem, phloem and occasional parenchymal cells, were structurally consistent in both mycorrhizal and non-mycorrhizal roots,
indicating that mycorrhizal inoculation did not impact the plant’s vascular transport system. In contrast, pathogen-infected roots exhibited disrupted epidermal and cortical cells. These findings contribute to understanding the structural dynamics of mycorrhizal and pathogenic interactions in mungbean roots.
