Eso sugiere que el hongo fue perdiendo parte de su información genética con el tiempo. Para un productor de avellanas, entender cómo funciona el enemigo es el primer paso para frenarlo con mejores variedades o tratamientos. Mientras tanto, el sector agrícola sigue dependiendo de métodos que no siempre alcanzan. Es un trabajo de laboratorio que todavía no cambia la cosecha, pero sí el mapa de quién la amenaza.","quienFirma":"Preprint en bioRxiv (institución principal no identificada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"b0884f24f5d462f2ae79f067db27f6e56dcccc4463044e63b5e0c2d8118413b4","sello":"d8ede9aae7b35eed7b8be856e904c9a46aabf17be476d81e49d6db6eeb2b94ef","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6586719,"aleatorio":"69c104ecd3cb13434712414db5b2ad3c4f3e8c23a6e958cf0c536314410db9d8","tiempo":"2026-10-26T16:36:30.000Z"},"nist":{"cadena":2,"pulso":2000553,"salida":"C52F940F6CB3ED0E0B156BE5FA3EFA2B75E456473C90354367E414D5115CEDF0D632503093B1A864228DF7BF37C390F188E14CB6127FE2E67FC4E9BF01B2FA0B","tiempo":"2026-10-26T16:36:00.000Z"},"noAntes":"2026-10-26T16:36:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 26 16:36:53 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Chromosome-scale nuclear and mitochondrial genome assemblies reveal extreme genome compartmentalization in the hazelnut pathogen Anisogramma anomala","descripcion":"Anisogramma anomala is an obligate biotrophic ascomycete and the causal agent of Eastern filbert blight, the most economically important disease of hazelnut in the United States. Here, we generated a chromosome-scale reference genome for A. anomala isolate OR-Ennis-d and characterized its nuclear and mitochondrial genome architecture. The 344-Mb nuclear genome was resolved into 9 predicted chromosomes and is repeat-rich, with transposable elements comprising 88.8% of the assembly. Although transposable elements are abundant, their divergence landscape and low retention of conserved protein domains support a history of past extensive transposon proliferation followed by widespread degeneratio","pubDate":"2026-10-26","url":"https://www.biorxiv.org/content/10.64898/2026.10.20.760510v1?rss=1"},"indexado":"2026-10-26T16:35:59.047Z"}}
