Contribution of dark septate fungi to the nutrient uptake and growth of rice plants Repositório Alice
VERGARA, C.; ARAUJO, K. E. C.; ALVES, L. S.; SOUZA, S. R. de; SANTOS, L. A.; SANTA-CATARINA, C.; SILVA, K. D.; PEREIRA, G. M. D.; XAVIER, G. R.; ZILLI, J. E..
The use of dark septate fungi (DSE) to promote plant growth can be beneficial to agriculture, and these organisms are important allies in the search for sustainable agriculture practices. This study investigates the contribution of dark septate fungi to the absorption of nutrients by rice plants and their ensuing growth. Four dark septate fungi isolates that were identified by Internal transcribed spacer phylogeny were inoculated in rice seeds (Cv. Piauí). The resulting root colonization was estimated and the kinetic parameters Vmax and Km were calculated from the nitrate contents of the nutrient solution. The macronutrient levels in the shoots, and the NO3?-N, NH4+-N, free amino-N and soluble sugars in the roots, sheathes and leaves were measured. The...

Dark septate endophytic fungi increase green manure-15N recovery efficiency, N contents, and micronutrients in rice grains. Repositório Alice
VERGARA, C.; ARAUJO, K. E. C.; URQUIAGA, S.; SANTA-CATARINA, C.; SCHULTZ, N.; ARAUJO, E. da S.; BALIEIRO, F. de C.; XAVIER, G. R.; ZILLI, J. E..
An understanding of the interaction between rice and dark septate endophytic (DSE) fungi, under green fertilization, may lead to sustainable agricultural practices. Nevertheless, this interaction is still poorly understood. Therefore, in this study, we aimed to evaluate the accumulation of macro- and micronutrients, dry matter, and protein and N recovery efficiency from Canavalia ensiformis (L.)-15N in rice inoculated with DSE fungi. An experiment under greenhouse conditions was conducted in a randomized complete block design comprising split-plots, with five replicates of rice plants potted in non-sterilized soil. Rice (Piauí variety) seedlings were inoculated with DSE fungi, A101 and A103, or left uninoculated (control) and transplanted into pots...
