Plant-Pathogenic Fungi in Seeds of Different Pea Cultivars in Poland

Abstract

Legume crops are exposed to infection by fungal pathogens, which often results in contamination with mycotoxins. The aim of this study was to evaluate the level of field resistance/susceptibility of edible and fodder pea cultivars to the colonization of seeds by fungal pathogens in two subsequent seasons, as well as to identify the pathogens present in the seeds of the tested cultivars. Alternaria spp. were the most common fungi isolated from pea seeds in both seasons, followed by Fusarium spp., Stemphylium spp., Ulocladium spp., Botrytis cinerea Pers., Epicoccum nigrum Link., and Phoma pinodella L. K. Jones. The highest percentage of infected seeds (55 %) was recorded for cultivar Ezop. The presence of a large number of fungi was found in 2012 for cultivars Santana, Tarchalska, Medal, Cysterski, Mentor, Lasso, and Ezop. Fodder cultivars displayed a lower infection level than edible cultivars. We can conclude that Alternaria spp. were the most frequent fungi present in pea seeds in Poland and Fusarium spp. were likely the most dangerous, having in mind their established mycotoxigenic abilities.

Host extract modulates metabolism and fumonisin biosynthesis by the plant-pathogenic fungus Fusarium proliferatum

“…The strains were collected, purified and characterized genetically and phenotypically during previous studies (Stępień et al, 2011b;Waśkiewicz et al, 2013). Strains from asparagus and pea were isolated from asymptomatic spears and seeds, respectively (Wilman et al, 2014), the remaining strains came from diseased host plants (data not shown). They are stored in the KF pathogenic fungi collection at the Institute of Plant Genetics, Polish Academy of Sciences, Poznań, Poland.…”

The frequency of occurrence of pathogenic and saprotrophic fungi in pea seeds in different regions of Poland

“…The predominant species ofsaprotrophic fungi were Alternaria alternata and Cladosporium cladosporioides (Table 3). Alternaria alternata was also most frequently isolated from pea seeds in Poland by Marcinkowska (2008) and Wilman et al (2014). In studies by Horoszkiewicz-Janka et al 2013and Okorski and Majchrzak (2008), pea seeds were colonized by both saprotrophic and pathogenic fungi.…”

“…Molecular techniques also supported the identification of three Fusarium species viz. F. verticilloides, F. proliferatum and F. poae in pea seeds grown in Poland (Wilman et al 2014).…”

Wildly Growing Asparagus (Asparagus officinalis L.) Hosts Pathogenic Fusarium Species and Accumulates Their Mycotoxins

“…2 and Table 1 ). As a consequence, the contamination of plant tissues with fumonisins appears as very likely, since F. proliferatum often synthesizes FBs in infected plant tissues [ 1 , 8 , 35 , 36 ]. Among 44 Fusarium isolates purified during the present study, while F. proliferatum and F. sporotrichioides were the prevailing species, only six F. oxysporum isolates were found (Table 1 and Fig.…”
