Discoloured seeds of amaranth plant infected by Alternaria alternata: physiological, histopathological alterations and fungal secondary metabolites associated or registered

Abstract: In the present study the aspects of discolouration that could influence both the production and consumption of amaranth were analyzed with the objectives to identify the presence of Alternaria alternata on seeds, to analyze possible changes in the anatomy of seed tissues and to detect the presence of fungal secondary metabolites. Component plating, histopathological and mycological analyses on discoloured seeds allowed i) location of propagules of A. alternata in all seminal components; ii) observation of hype… Show more

“…The mycelia of all isolates were stored at −80°C. Total genomic DNA was extracted from all isolates using the CTAB method (Noelting et al 2016). A NanoDrop ND-1,000 spectrophotometer (LMS Co., Ltd., Tokyo, Japan) was used to check the quality and concentration of genomic DNA.…”

“…Teniendo en cuenta, que A. alternata afecta la germinación de las semillas (Noelting et al, 2004; y sus propágulos pueden hallarse en las cubiertas seminales y en el embrión aún en semillas previamente desinfectadas (Noelting et al, 2016), es probable que los incrementos de germinación de las semillas tratadas con fungicidas se deban al control de los mismos sobre los propágulos del patógeno.…”
