A new stem canker disease of Eucalyptus caused by Botryodiplodia theobromae in India

Abstract: A new stem canker disease of Eucalyptus caused by Botryodiplodia theobromae is reported from India. The disease caused up to 20% mortality. Survey and pathogenicity trials suggest that E. tereticornis is more susceptible than E. grandis to stem canker.

In vitro evaluation of fungicides against Cylindrocladium spp. causing diseases of Eucalyptus in Kerala, India.

Abstract: A total of 22 fungicides were evaluated in vitro for their efficacy against Cylindrocladium quinqueseptatum (CQ), C. ilicicola (CI), C. floridanum (CF), C. parvum (CP), and C. camelliae (CC) causing various diseases of Eucalyptus in Kerala, India. Though there were a number of fungicides effective (ED100) in the comdial germination and poisoned food techniques, only carbendazim provided complete inhibition of CQ, CI and CC in the soil-fungicide screening technique; carbendazim was also highly effective against CF and CP. C. ilicicola appeared to be more tolerant than other species of Cylindrocladium as only a few fungicides were found to be effective against it even in the conidial germination technique. On comparison of the three fungicidal evaluation techniques, it is concluded that, for a pathogen producing microsclerotia, like Cylindrocladium, the soil-fungicide screening technique is the most appropriate one for obtaining reliable results.

Cylindrocladium causing seedling diseases of Eucalyptus in Kerala, India

Abstract: Cylindrocladium camelliae and C. clavatum are reported to cause diseases of Eucalyptus grandis and E. tereticornis seedlings.

A new species

Abstract: We redescribe the only previously known species of Myrsidea from bulbuls, M. pycnonoti Eichler. Sixteen new species are described; they and their type hosts are: M. phillipsi ex Pycnonotus goiavier goiavier (Scopoli), M. gieferi ex P. goiavier suluensis Mearns, M. kulpai ex P. flavescens Blyth, M. finlaysoni ex P. finlaysoni Strickland, M. kathleenae ex P. cafer (L.), M. warwicki ex Ixos philippinus (J. R. Forster), M. mcclurei ex Microscelis amaurotis (Temminck), M. zeylanici ex P. zeylanicus (Gmelin), M. plumosi ex P. plumosus Blyth, M. eutiloti ex P. eutilotus (Jardine and Selby), M. adamsae ex P. urostictus (Salvadori), M. ochracei ex Criniger ochraceus F. Moore, M. borbonici ex Hypsipetes borbonicus (J. R. Forster), M. johnsoni ex P. atriceps (Temminck), M. palmai ex C. ochraceus, and M. claytoni ex P. eutilotus. A key is provided for the identification of these 17 species.

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

Abstract: 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.

Seed priming for abiotic stress tolerance: an overview

Abstract: 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.
