dc.description.abstractTrichoderma spp. are considered in the category of biofertilizer microbes that have ability to increase nutrient uptake capacity and contribute in plant development. In the present investigation, recruitment of Trichoderma asperellum T42 with pea seeds increased total nitrogen uptake efficiency that promoted root traits, total biomass and yield. Molecular evidences revealed that T42 interaction with plant roots enhanced nitric oxide (NO) generation at 40, 70 and 90�days involved in several plant physiological processes. Interestingly, these growth parameters were elevated higher when plants were fed with nitrate nutrient as compared to ammonium fed condition at 40 and 70�days. NO generation in nitrogen nutrient confirmed that NO generation was produced via nitrate reductase (NR) dependent pathway. Several nitrate and ammonium transporters help increase in situ NO generation and contributed to increased lateral root initiation, in pea. Higher expression of nitrate transporter (NRT) genes in response to Trichoderma recruitment in nitrate fed condition and suppressive expression effect of ammonium transporter (AMT1.1) suggested that NRTs have more affinity for NO3? acquisition through pea roots. Among the NRTs, NRT2.1 and NRT1.2 were more upregulated as compared to control plant roots. Overall, our findings suggested that Trichoderma recruitment with pea seeds improved plant growth and yield, particularly more in nitrate fed condition providing insight of the strategy for not only pea but probably for other commercial leguminous crops which suffer from fluctuating nitrate availability in soil. � 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
