      Peanut smut, caused by Thecaphora frezii, increased its incidence and prevalence in the main growing region of Argentina in the last decade becoming the main peanut disease. Despite this fact, growers continue producing ...

    • First draft genome of Thecaphora frezii, causal agent of peanut smut disease 

      Arias, Renee S.; Conforto, Erica Cinthia; Orner, Valerie A.; Carloni, Edgardo José; Soave, Juan H.; Massa, Alicia N.; Lamb, Marshall C.; Bernanrdi Lima, Nelson; Rago, Alejandro Mario (BMC, 2023-02-16)
      Objectives: The fungal pathogen Thecaphora frezii Carranza & Lindquist causes peanut smut, a severe disease currently endemic in Argentina. To study the ecology of T. frezii and to understand the mechanisms of smut resistance ...

    • Impact of yellow leaf virus on sugarcane commercial fields 

      Asinari, Florencia; Perez Gomez, Sergio Gregorio; Easdale, C.; Rago, Alejandro Mario; Balzarini, Monica; Cafrune, Eva Encarnacion (Springer, 2020-11-17)
      A survey of Sugarcane yellow leaf virus (SCYLV) was conducted in northern Argentina in 2015 and 2016 using tissue blot immunoassay (TBIA). Results showed plant infection rates of 2.2–86.7% in sugarcane commercial fields ...

    • Low water availability increases susceptibility to peanut smut (Thecaphora frezzii) in peanut crop 

      Paredes, Juan Andrés; Guzzo, María Carla; Monguillot, Joaquín Humberto; Asinari, Florencia; Posada, Gisella A.; Oddino, Claudio M.; Giordano, Damian F.; Morichetti, Sergio A.; Torres, Adriana M.; Rago, Alejandro Mario; Monteoliva, Mariela Ines (Wiley, 2023-10-23)
      Peanut smut (causal agent Thecaphora frezzii) and seasonal drought are the two main factors reducing peanut yields in Argentina. There are no previous studies about the effect of drought on peanut smut occurrence. We ...

    • Mitogenome and Nuclear-encoded Fungicide-target Genes of Thecaphora frezii - Causal Agent of Peanut Smut
