High-density SNP map facilitates fine mapping of QTLs and candidate genes discovery for Aspergillus flavus resistance in peanut (Arachis hypogaea)

Intramuscular fat (IMF) and fatty acid composition are characteristics that are used as important indicators of evaluating high quality pork and contribute to the economic benefits of the pig farming industry. In this study, quantitative trait loci (QTL) fine mapping of chromosome 12 was performed in a population of F2 intercross between Yorkshire (YS) and Korean native pigs (KNPs) by adopting combined linkage and linkage disequilibrium method using high-density SNP chips. QTLs for IMF (H3GA0034813 to H3GA0034965) and oleic acid (C18:1) (ASGA0054380 to ALGA0066299) were located at 120 cM (54.112–57.610 kb) and 85 cM (36.097–38.601 kb), respectively, within chromosome 12 (Sscrofa11.1 genomic reference). In addition, 31 candidate genes present within the IMF QTL region and 28 candidate genes existing within C18:1 QTL region were chosen. In order to understand the function of these candidate genes at the molecular level, these candidate genes were functionally categorized by studying gene ontology and analyzing network and pathway. Among the 59 candidate genes within the region of IMF QTL and C18:1 QTL, five (MYH1, MYH2, MYH4, ACACA, and RPS6KB1) directly interacting candidate genes were found. Furthermore, the RPS6KB1 gene was assumed to be an important candidate gene that is involved in leptin and insulin signaling pathway and participates in controlling adipogenic differentiation, fat deposition, and fatty acid composition, which is related to obesity of pigs.

Apparent Susceptibility

Abstract An assay of cured, hand-shelled seeds of various peanut genotypes for tolerance to members of the Aspergillus flavus group of fungi has been performed in Florida for the years 1971–1974. The assay involved exposing peanut seed at 20–30% moisture to conidia of A. parasiticus or A. flavus in petri plates and incubating at 25 C. After 1 week, the percentage of the seeds with sporulating colonies of the test fungus was determined. Typically, individual lines or cultivars were evaluated on the basis of the average of three plates. However, second or third assays of the same seed lots were done on 45 occasions during the 4 year period. More than 95% of these repeated assays yielded data similar to those from the original assay. However, different seed lots of the same line also were assayed and did not always yield similar results unless the dates of digging, methods of curing and location of the plantings were the same. Some shifts in susceptibility were quite extreme. One lot of stackpole cured ‘Altika’ resulted in 12% colonized seeds in the assay but 77% of a windrow-cured seed lot, dug on the same day from the same plot had colonies of the test fungi. No particular change in the harvesting procedure was consistently associated with increases or decreases in apparent susceptibility. Based on tests of all seed lots of 15 commonly grown cultivars during the years 1971–1974. ‘Florunner’ was the most tolerant cultivar and ‘Tifspan’ was the most susceptible.

As cascas de amendoim (Arachis hypogaea L.) são de grande importância para confecção de cama de frangos, de gado de leite e como fonte de fibras para ruminantes, portanto a elucidação dos mecanismos de contaminação por fungos toxigênicos e por micotoxinas em amendoim é imprescindível, especialmente para que medidas preventivas possam ser tomadas. Realizou-se, este trabalho, em Junqueirópolis, Estado de São Paulo, Brasil. Os principais fungos isolados nas cascas de amendoim foram Fusarium ssp. (78,75 %), Rhizopus ssp. (14,1 %) e A. flavus (11,75 %). No solo foram isolados Penicillium spp., Fusarium spp. e Aspergillus flavus, entre outros. Aflatoxinas foram detectadas em amostras de cascas de amendoim a partir do estágio de granação em concentrações que variaram de 5,42 μg/kg a 218,52 μg/kg. Ácido ciclopiazônico e fumonisinas B1 e B2 não foram detectadas. A presença de A. flavus e aflatoxinas nas amostras, revela a importância de um controle das cascas de amendoim antes de sua utilização. Boas práticas agrícolas são indicadas para região, uma vez que a contaminação das vagens ocorreu antes da colheita.
