The Intracytoplasmic Sperm Injection (ICSI) is a kind of micromanipulative technique in which a single sperm is directly injected into the ooplasm of a matured oocyte using a microscopic needle. It is a type of in vitro fertilization which is mainly used to treat severe male factor infertility in human. This procedure can bypass many barriers of fertilization including the process of sperm penetration through cumulus-corona cells, zona pellucida and oolemma during fertilization by directly depositing the sperm into the ooplasm. The introduction of ICSI in assisted reproduction has helped to investigate and understand the early events of fertilization such as sperm capacitation, the acrosome reaction and pronucleus formation. Like humans, domestic animals including goats, suffer from infertility or sub-fertility, which lowers their lifetime productivity and reduces the number of offspring that could be obtained from a sire or dam. The prevalence of this problem coupled with the desire of people to understand and subsequently control the reproductive processes has led to the development of novel assisted reproductive technologies (ARTs) like ICSI. It is one of the modern ART which can be used in livestock for the improvement and preservation of livestock genetics and the enhancement of reproductive efficiency. Till now, ICSI technique - one of the modern ARTs - has been successfully used in humans, rodents and other animals, especially in the cattle. The present study describes different aspect of ICSI including history, types of micromanipulative techniques, remodeling of fertilization process, oocyte activation and factors affecting outcomes of ICSI etc. © 2010 Asian Network for Scientific Information.

The Gray eel catfish Plotosus canius is a vulnerable species in Bangladesh. The wild populations are declining as a result of over-exploitation, destruction of spawning grounds, various ecological changes in their natural habitats, and lack of appropriate management. Establishment of suitable sanctuaries in selected areas of estuaries, streams, canals and lakes is suggested for the conservation of the populations. © The Author(s) 2015.

2,4-Diacetylphloroglucinol (DAPG) produced by Pseudomonas fluorescens, shows toxicity to many microorganisms including fungi, bacteria, and peronosporomycetes. Zoosporogenesis and motility of zoospores are critical for a complete disease cycle and pathogenicity of the peronosporomycete phytopathogens. The aim of this study was to test the effects of DAPG and its derivatives on zoosporogenesis and motility of zoospores of a downy mildew pathogen, Plasmopara viticola, and a damping-off pathogen, Aphanomyces cochlioides. In both cases, DAPG inhibited zoosporogenesis (5 μg/ml) and the motility of zoospores (10 μg/ml) in a dose-dependent manner. Generally, zoospores became immotile shortly after exposure to DAPG followed by lysis. However, a fraction of DAPG treated A. cochlioides zoospores formed round cystospores instead of lysis and then germinated with excessively-branched germ tubes. All derivatives of DAPG had similar inhibitory activities but at varying doses. Among them, 2,4-dipropylphloroglucinol exerted the highest inhibitory activity against both zoosporogenesis and motility of zoospores. This revealed that the degree of hydrogen atoms substitution in the benzene ring by acyl groups and the length of substituted acyl groups were related to the level of bioactivity. This is the first report of inhibitory activities of DAPG and its derivatives against zoosporogenesis and motility of zoospores of two important peronosporomycete phytopathogens. © 2011 Springer Science+Business Media B.V.

Intrusion of saline water and soil salinity is a major threat of climate change to agriculture. Rice is the most important crop affected by salinity in the coastal area of Bangladesh. The objective of this paper is to develop tools for ex ante cost-benefit assessment, with an integration of knowledge of farmers, industry experts and scientists to develop new salinity and drought resistant (SDR) transgenic rice variety. Total incremental benefits of introducing SDR transgenic rice to replace traditional varieties are expected to be $948 ha-1 yielding a net benefit of $934 ha -1. The introduction of transgenic SDR rice in Bangladesh would have sizable social benefits. The total amount of nondiscounted economic surplus from producing SDR transgenic rice over 10 years is projected at US$188 million with a producer surplus of $114 million. The internal rate of return (IRR) is 34% with a net present value (NPV) of $117 million. © 2011 Inderscience Enterprises Ltd.

Greater production of cereals brings forth higher production cost and pollutes the soil environment due to excessive use of chemical fertilizers. Therefore, crop scientists are exploring an alternative source namely biofertilizers which are cost effective and environment friendly. In the biofertilizer technology, Rhizobium-legume is most common and widely used in different countries. Recently, it is also found that rhizobia can make an association with graminaceous plants such as rice, wheat, maize, barley millets and other cereals some time as endophytic without forming any nodule-like structure or causing any disease symptoms. Increasing the ability of rhizobia in biofertilizer, crop enhancing activity in nonlegumes especially cereal grains would be a useful technology for increased crop yields among resource-poor farmers. Recent findings showed both more crop enhancing and biofertilizer attributes in cereal crops due to rhizobial inoculation. In addition, plant nutrients like P, K, Ca, Mg and even Fe accumulation were also observed. Therefore, further research in this area will be able to develop a sustainable biofertilizer technology for greater and environment friendly cereal production system. © 2010 Academic Journals.
