The ability of Aspergillus caelatus, a species in Aspergillus section Flavi, to produce synnemata and sclerotia was investigated. Forty-eight isolates of A. caelatus differed widely in their production of synnemata and sclerotia; 83% of the isolates produced varying numbers of synnemata and sclerotia, and 17% produced neither sclerotia nor synnemata. Most strains produced synnemata and mostly sessile and few stipitate sclerotia on the same Czapek agar (CZA) plate. Two strains of A. caelatus were selected for further study because of the contrasting morphology of their synnemata and sclerotia. Those strains are NRRL 25528, the type species and a representative of the synnema- and black sclerotium-forming isolates, and NRRL 26119, considered an atypical strain that produced numerous synnemata and few slightly melanized or tan sclerotia. The induction and maturation of sclerotia in A. caelatus were affected greatly by the type of media as well as the kind and concentration of the carbon and nitrogen sources. CZA induced synnema and sclerotium production in both strains, whereas other media did not. Production of abundant synnemata and sclerotia also occurred when the carbon source in CZA is replaced with dextrose, xylose, cellobiose, melibiose and trehalose. CZA amended with serine, threonine, KNO(3) and NaNO(3) induced the production of numerous sclerotia and synnemata. For both strains, the optimal levels of sucrose and NaNO(3) for maximum production of synnemata or sclerotia were 3 and 0.9%, respectively. The production of synnemata and stipitate/sessile sclerotia by several wild-type strains of A. caelatus further substantiates previous suggestions for an evolutionary link between Aspergillus section Flavi and synnematal species A. togoensis, which also produces stipitate sclerotia.

Casuarina glauca displays high levels of salt tolerance, but very little is known about how this tree adapts to saline conditions. To understand the molecular basis of C. glauca response to salt stress, we have analyzed the proteome from branchlets of plants nodulated by nitrogen-fixing Frankia Thr bacteria (NOD+) and non-nodulated plants supplied with KNO3 (KNO3+), exposed to 0, 200, 400, and 600 mM NaCl. Proteins were identified by Short Gel, Long Gradient Liquid Chromatography coupled to Tandem Mass Spectrometry and quantified by Sequential Window Acquisition of All Theoretical Mass Spectra -Mass Spectrometry. 600 proteins were identified and 357 quantified. Differentially Expressed Proteins (DEPs) were multifunctional and mainly involved in Carbohydrate Metabolism, Cellular Processes, and Environmental Information Processing. The number of DEPs increased gradually with stress severity: (i) from 7 (200 mM NaCl) to 40 (600 mM NaCl) in KNO3+; and (ii) from 6 (200 mM NaCl) to 23 (600 mM NaCl) in NOD+. Protein-protein interaction analysis identified different interacting proteins involved in general metabolic pathways as well as in the biosynthesis of secondary metabolites with different response networks related to salt stress. Salt tolerance in C. glauca is related to a moderate impact on the photosynthetic machinery (one of the first and most important stress targets) as well as to an enhancement of the antioxidant status that maintains cellular homeostasis.
