Endophyte microorganisms are organisms that live inside plants without causing any apparent damage to their hosts. Since all plants exhibit endophyte microorganisms, it is believed that mutual association is of great importance in nature. Luehea divaricata (Martius & Zuccarini), known popularly in Brazil as agoita-cavalo, is a big-sized tree with a wide distribution in the country that possesses medicinal qualities for: dysentery, leucorrhea, rheumatism, blennorrhoea, tumors, bronchitis, and depuration. This research aims at isolating and molecularly characterizing fungi isolates from L. divaricata by sequence analysis of ITS1-5.8S-ITS2 rDNA. Further, the colonization of endophyte in the host plant by Light and Scanning Electron Microscopy will... |

Lolitrem-B is a neurotoxic substance that causes the ryegrass staggers syndrome in cattle, sheep, and horses consuming ryegrass (Lolium perenne L.) infected with endophytic fungus Neotyphodium lolii (Latch, Christensen, and Samuels) Glenn, Bacon, and Hanlin. Due to the increasing use of ryegrass pasture in southern Chile, it is necessary to know the content of lolitrem-B to optimize grazing management and reduce the effect on animal health. The objective of this study was to implement a method to determine lolitrem-B in ryegrass. Ryegrass samples were used without the endophyte, freeze-dried, and kept in darkness at -18 ºC to establish the method. Then, a pure lolitrem-B standard was added and the toxin was extracted with a mixture of chloroform-methanol... |
