Improvement of seed quality and field emergence ofFusarium moniliforme infected sorghum seeds using biological agents

“…23 The antagonistic nature of C globosum was not studied well but the secondary metabolites of C globosum have reduced the disease incidence in pearl millet.15 All the üve diþerent varieties of sorghum have shown a much increased vigour when treated with biological agents than when treated with the chemical agent Bavistin. The reason for the increase in vigour may be certain chemicals produced by P ýuorescens, T harzianum and C globosum which are known to have increased growth rate as reported by Lynch and Hobbie16 and Kimura et al 24 A similar type of higher üled emergence was also observed in the üeld conditions in all the diþerent cultivars of sorghum. In recent years much attention has been given to non-chemical systems for seed treatment as well as to protect them against seedborne pathogens.…”

Bioactive metabolites from Alternaria brassicicola ML-P08, an endophytic fungus residing in Malus halliana

“…Furthermore, 1 and 2 showed weak antibacterial activity while compounds 5-7 were inactive to almost all test microorganisms. Compound 3 have been isolated from fungi belonging to the genera Alternaria (Kimura et al 1992) and Hypoxylon (Gu et al 2007). Apart from its strong antimicrobial activity, Kimura et al (1992) found that 3 and its analog could promote the growth of the roots of Lactuca sativa.…”

Herbarin A (4), an a-pyrone derivative, has only been isolated from a strain of sponge-derived Cladosporium herbarum and was found to be inhibitory against Artemia salina (Jadulco et al 2002).…”

Balticols A–F, New Naphthalenone Derivatives with Antiviral Activity, from an Ascomycetous Fungus

“…Although the observed NOEs are not sufficient to assign a relative configuration for 6, at least Me and MeO groups seem to be oriented differently compared to 7. [9]. Due to the signal broadening in our sample, the signal of the chelated OH group was not observed.…”
