Fungi are an understudied, biotechnologically valuable group of organisms. Due to 
the immense range of habitats that fungi inhabit, and the consequent need to compete against a diverse array of other fungi, bacteria, and animals, fungi have developed numerous survival mechanisms. The unique attributes of fungi thus herald great promise for their application in biotechnology and industry. Moreover, fungi can be grown with relative ease, making production at scale viable. The search for fungal biodiversity, and the construction of a living fungi collection, both have incredible economic potential in locating organisms with novel industrial uses that will lead to novel products. This manuscript reviews fifty ways in which fungi can potentially be utilized as biotechnology. We provide notes and examples for each potential exploitation and give examples from our own work and the work of other notable researchers. We also provide a flow chart that can be used to convince funding bodies of the importance of fungi for biotechnological research and as potential products. Fungi have provided the world with penicillin, lovastatin, and other globally significant medicines, and they remain an untapped resource with enormous industrial potential.

The amazing potential of fungi: 50 ways we can exploit fungi industrially

Plants are exposed to any number of potentially adverse environmental conditions such as water deficit, high salinity, extreme temperature, submergence, etc. These abiotic stresses adversely affect the plant growth and productivity. Nowadays various strategies are employed to generate plants that can withstand these stresses. In recent years, seed priming has been developed as an indispensable method to produce tolerant plants against various stresses. Seed priming is the induction of a particular physiological state in plants by the treatment of natural and synthetic compounds to the seeds before germination. In plant defense, priming is defined as a physiological process by which a plant prepares to respond to imminent abiotic stress more quickly or aggressively. Moreover, plants raised from primed seeds showed sturdy and quick cellular defense response against abiotic stresses. Priming for enhanced resistance to abiotic stress obviously is operating via various pathways involved in different metabolic processes. The seedlings emerging from primed seeds showed early and uniform germination. Moreover, the overall growth of plants is enhanced due to the seed-priming treatments. The main objective of this review is to provide an overview of various crops in which seed priming is practiced and about various seed-priming methods and its effects.

11 – plant diseases associated with mycoplasma-like organisms

Concealed antigens from the adult of Hyolomma anatolicum anatolicum were isolated by immunoaffinity chromatography using anti-gut IgG as ligands. The bound antigens were characterized by SDS-PAGE and 2 proteins of 106.7 and 68 kDa were identified. Immunization of crossbred calves (Bos taurus × Bos indicus) with 1.7 mg ofthe bound antigens adjuvanted with FCA/IFA animal decreased 74.4 and 52.2% population of nymphs and adults respectively. Besides, a significant percentages of abnormally fed larvae (P < 0.001) and nymphs (P < 0.05) was dropped from the immunized animals. Western blot analysis detected protein band of 68 kDa as the antigen responsible for the induction of resistance in the host.

Hydatid disease, a zoonosis, occurs worldwide but its prevalence is high in those countries where sheep and cattle raising constitute an important industry due to close association between man, sheep and dog. Most common sites of involvement by hydatid disease are liver followed by lung. Splenic involvement by hydatid disease is very rare accounting for only 0.9% to 8.0% of all cases. Other rare sites include heart, pancreas and muscles. We report a case of histopathologically confirmed primary hydatid cyst spleen in an 18 year old male, which is a rare entity. Hydatid disease should be considered in the differential diagnosis of cystic lesions of spleen.

Primary Hydatid Cyst of Spleen: A Rare Entity

Summary The Sub-section Albidae, the only major taxomonic grouping of Populus immune to both Melampsora larici-populina Kleb, and M. medusae Thum, leaf rusts in the field in Australasia, is worthy of fuller investigation for use in commercial and aesthetic plantings. Preliminary investigations indicate that race-specific resistance is common in the Aigeiros Section of Populus and this has significant implications in the establishment of clones of this Section. Rust resistance, disease progress pattern and length of growing season of clones are important considerations in the selection of clones for certain purposes in particular environments.

Forms and degrees of resistance in Populus spp. to the Melampsora leaf rusts occurring in Australasia

Urediniospores of leaf rust of poplar ( Melampsora larici-populina Kleb.) were harvested from the leaves of a variety of poplar clones grown in the field. These spores were suspended in distilled water and serially diluted. For optical densities 0.006 ⩾ x ⩽ 0.332 the number of spores per ml ( x ) (from haemocytometer counts), was linearly related to the optical density ( y ) determined at 640 nm, by the formula y = 2.411 e -03 + 8.548 e -07 x ( R = 0.998; P Populus x euramericana clones. The use of this technique for calculating spore production per unit leaf area as a parameter of disease intensity is discussed.
