| Title | Native <i>Trichoderma</i> Induced the Defense-Related Enzymes and Genes in Rice against <i>Xanthomonas oryzae</i> pv. <i>oryzae</i> (<i>Xoo</i>). | |

Abstract: The application of <i>Trichoderma</i> is a form of biological control that has been effective in combating <i>Xanthomonas oryzae</i> pv. <i>oryzae</i>, the causative agent of the devastating disease known as bacterial blight of rice. In this present study, four strains of <i>Trichoderma,</i> viz., <i>T. paraviridescens</i> (BDISOF67)<i>, T. erinaceum</i> (BDISOF91), <i>T. asperellum</i> (BDISOF08), and <i>T. asperellum</i> (BDISOF09), were collected from the rice rhizosphere and used to test their potentiality in reducing bacterial blight. The expression patterns of several core defense-related enzymes and genes related to SA and JA pathways were studied to explore the mechanism of induced resistance by those <i>Trichoderma</i> strains. The results primarily indicated that all <i>Trichoderma</i> were significantly efficient in reducing the lesion length of the leaf over rice check variety (IR24) through enhancing the expression of core defense-related enzymes, such as PAL, PPO, CAT, and POD activities by 4.27, 1.77, 3.53, and 1.57-fold, respectively, over control. Moreover, the results of qRT-PCR exhibited an upregulation of genes <i>OsPR1</i>, <i>OsPR10</i>, <i>OsWRKY45</i>, <i>OsWRKY62</i>, <i>OsWRKY71</i>, <i>OsHI-LOX</i>, and <i>OsACS2</i> after 24 h of inoculation with all tested <i>Trichoderma</i> strains. However, in the case of RT-PCR, no major changes in <i>OsPR1</i> and <i>OsPR10</i> expression were observed in plants treated with different <i>Trichoderma</i> strains during different courses of time. Collectively, <i>Trichoderma</i> induced resistance in rice against <i>X. oryzae</i> pv. <i>oryzae</i> by triggering these core defense-related enzymes and genes associated with SA and JA pathways. |
