Contribution of dark septate fungi to the nutrient uptake and growth of rice plants. Repositório Alice
TORRES JÚNIOR, C. V.; ARAUJO, K. E. C.; ALVES, L. S.; SOUZA, S. R. de; SANTOS, L. A.; SANTA CATARINA, C.; SILVA, K. D.; DUARTE, G. M. P.; 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 DSE to the absorption of nutrients by rice plants and their ensuing growth. Four DSE isolates that were identified by ITS 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 rice roots were significantly colonized by all of the...

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...

Dark septate endophytic fungi help tomato to acquire nutrients from ground plant material. Repositório Alice
VERGARA, C.; ARAUJO, K. E. C.; URQUIAGA, S.; SCHULTZ, N.; BALIEIRO, F. de C.; MEDEIROS, P. S.; SANTOS, L. A.; XAVIER, G. R.; ZILLI, J. E..
Dark septate endophytic (DSE) fungi are facultative biotrophs that associate with hundreds of plant species, contributing to their growth. These fungi may therefore aid in the search for sustainable agricultural practices. However, several ecological functions of DSE fungi need further clarification. The present study investigated the effects of DSE fungi inoculation on nutrient recovery efficiency, nutrient accumulation, and growth of tomato plants fertilized with organic and inorganic N sources. Two experiments were carried out under greenhouse conditions in a randomized blocks design, with five replicates of tomato seedlings grown in pots filled with non-sterile sandy soil. Tomato seedlings (cv. Santa Clara I-5300) inoculated with DSE fungi (isolates...
