Fusariumes un género fúngico amplio y diverso de diferentes complejos deespecies, causante de una gran variedad de enfermedades en plantas, productor dediversas toxinas y representa un importante patógeno oportunista en humanos. Laidentificación de las especies de Fusarium ha sido por mucho tiempo una tareacompleja y controversial. Esto es debido principalmente a la aplicación de diferentessistemas taxonómicos y la inherente variabilidad morfológica de algunas de estasespecies. Estas características requieren de la revisión por parte de un expertomicólogo, con el fin de lograr un acertado y confiable diagnóstico, el cual es crucialen el manejo de enfermedades o infecciones y estudios de diversidad genética. EnColombia, se ha reportado un incremento anual del 317 % de casos de infeccionescausadas por Fusarium, entre 1995 y 2003, sin embargo en centros especializados anivel nacional en micología médica, no se lleva a cabo un diagnóstico a nivel deespecie. El objetivo de este estudio fue el de establecer la identidad de aislamientosclínicos de Fusarium, mediante el uso de un marcador molecular. Para lograr esteobjetivo se llevó a cabo la identificación de los 59 aislamientos mediante consulta enla base de datos Fusarium-ID con base en secuencias codificantes del factor deelongación de la traducción EF-1a. Los resultados obtenidos permitieron observar laagrupación de los 59 aislamientos en tres complejos de especies: Fusariumoxysporum(FOSC), Fusarium solani (FSSC) y Fusarium incarnanatum-equiseti(FIESC). Basado en los resultados, se observa que el uso de las secuenciascodificantes para el factor de elongación de traducción permiten una confiableclasificación de los aislamientos de origen clínico y permite ratificar la utilidad queposee este marcador molecular en los distintos complejos de Fusarium.

This study examines the effectiveness of mycorrhizal Rhizoctonia resistance induction in Phalaenopsis amabilis against Fusarium sp. Fusarium solani is known as pathogens that attack many orchids P. amabilis (Chung et al., 2011) compared to other pathogenic fungi. Attack of Fusarium sp. will cause rot and yellow colored leaves. Until now there has been known as a biological control orchid against Fusarium sp. In this study tested the endurance locations in Sleman and Surakarta to see the effectiveness of a good orchid growth induced by Rhizoctonia mycorrhizal or not to attack by Fusarium sp. The results of the study showed that mycorrhizal Rhizoctonia able to inhibit the attack of Fusarium sp. It is shown by the value of the index of disease resistance  (DSI) in P. amabilis orchid mycorrhizal Rhizoctonia induced lower than that not induced. Mycorrhizal Rhizoctonia induction results in Sleman provide a more real than mycorrhizal Rhizoctonia induction in Surakarta.

Aim. To define the priority trends of apple breeding in the southern steppe of Ukraine and to identify varieties – sources of high valuable-for-breeding indices for building up a working collection. Results and Discussion. Spring frosts and wet weather in May-June contributing to development of the scab pathogen (Venturia inaequalis), high temperature and water deficit in the 2nd half of the growing period, when fruits grow and ripen, are the major stress weather/climatic factors for apple trees in the southern steppe of Ukraine. Therefore, the priority in breeding is given to developing varieties that would be resistant to several unfavorable factors. At the same time, commercial use of new varieties is possible provided high commercial quality indicators of fruits. High resistance of buds to spring frosts was observed in varieties Vechirnia Zoria, Moldavskoye Krasnoye, and Prima. Oligogenic varieties (genes Vm and Vf), including Harant, Skifske Zoloto, and Liberty, showed no signs of scab development. Varieties with polygenic resistance to this disease were identified; they included Vechirnia Zoria, Ornament, Carola. Drought-tolerant varieties with high water-holding capacity of leaves and their turgor restoration after wilting, including Carola, Florina, and Prima, were selected by a laboratory method. Assessment of drought tolerance in the field made it possible to enrich this group with numerous varieties. Varieties giving fruits with high commercial qualities on insufficient water availability, such as Vechirnia Zoria, Harant, Moldavskoye Krasnoye, Ornament and others, were distinguished. Varieties combining resistance to several unfavorable abiotic and biotic factors with high marketability traits of fruits were singled out. Among them. Harant, Delicious Spur, Liberty, and Prima should be mentioned. Conclusions. The development of varieties with complex tolerance to spring frosts, drought, scab pathogen and high qualities of fruits is the priority trend in the breeding of apple trees in the southern steppe of Ukraine. Varieties - sources of individual valuable traits and their various combinations were identified. Varieties Vechirnia Zoria, Moldavskoye Krasnoye, Ornament, and Golden Resistant combine the maximum number of valuable-for-breeding features. It is varieties-sources of several traits that should make up a working collection of apple trees to increase the breeding efficiency.

Six new fusarin derivatives, fusarins G–L (1–6), together with five known compounds (5–11) were isolated from the marine-derived fungus Fusarium solani 7227. The structures of the new compounds were elucidated by means of comprehensive spectroscopic methods (1D and 2D NMR, HRESIMS, ECD, and ORC) and X-ray crystallography. Compounds 5–11 exhibited potent anti-inflammatory activity by inhibiting the production of NO in RAW264.7 cells activated by lipopolysaccharide, with IC50 values ranging from 3.6 to 32.2 μM. The structure–activity relationships of the fusarins are discussed herein.
