Peptidyl-prolyl cis–trans isomerases (PPIases) are the only class of enzymes capable of cis–trans isomerization of the prolyl peptide bond. The PPIases, comprising of different families viz., cyclophilins, FK506-binding proteins (FKBPs), parvulins and protein phosphatase 2A phosphatase activators (PTPAs), play essential roles in different cellular processes. Though PPIase gene families have been characterized in different organisms, information regarding these proteins is lacking in Penicillium species, which are commercially an important fungi group. In this study, we carried out genome-wide analysis of PPIases in different Penicillium spp. and investigated their regulation by salt stress in a halotolerant strain of Penicillium oxalicum. These analyses revealed that the number of genes encoding cyclophilins, FKBPs, parvulins and PTPAs in Penicillium spp. varies between 7–11, 2–5, 1–2, and 1–2, respectively. The halotolerant P. oxalicum depicted significant enhancement in the myceli...

Involvement of the brain by neurotropic, dematiaceous fungi namely Cladosporium bantianum is extremely rare. The disease is very resistant to treatment and prone for frequent relapses despite treatment with amphotericin B and flucytosine, the drugs of choice for the infection. Surgery is often required for resection of the fungal granuloma. Isolation of the fungus from the tissue specimens and its culture, showing dark colored fungal colonies clinches the diagnosis. Animal inoculation studies can provide insights to the portal of entry of the organism. We hereby report a case of fungal granuloma of the brain due to C. bantianum, which responded favorably to intensive antifungal treatment alone, with relevant review of literature.

Expression of wheat germ agglutinin (WGA) gene inthe developing embryos of wheat (Triticumaestivum L. cv. C-306) was studied in relation toabscisic acid (ABA) accumulation under water stressconditions. Imposition of water stress resulted inelevated ABA levels in the embryos at threedevelopmental stages (18, 24 and 30 DPA). On thecontrary, the effect of drought stress on WGAaccumulation was stage dependent with significantincrease
