Abstract Ochratoxin A (OTA), one of the most dangerous mycotoxins for human health, has been subjected to numerous studies for separation and detection in minimal amounts. Aptamers as novel recognition elements have been employed to fabricate ultrasensitive biosensors for the detection of OTA and designing delicate analytical tools. This review attempted to comprehensively examine all reported aptamer-based detection and separation platforms for ochratoxin. The most relevant databases were considered to discover all specific aptamers for dealing with OTA. Aptamer-based detection and separation devices specified for OTA were searched for, analyzed, discussed, and classified based on their specifications. The optical aptasensors have… More >

Abstract The effects of fusaric acid, a mycotoxin produced by Fusarium sp, were investigated in relation to its action on corn seedlings. The mycotoxin inhibited the development of corn seedlings at 0.2 mM, causing root length reduction. Anatomically, alterations were only visible from 0.5 mM fusaric acid, directly influencing the cell differentiation process. Precocious differentiation reduces the elongation region. This explains (1) that root shortening is morphologically visible, and (2) the differentiation of a great number of lateral roots nearby the apex, which can be seen in longitudinal cuts. More >
