Several fungal contaminants of mushrooms have been serving as the major restraining factor in the growing mushroom industry for a long time. Fungal contaminants like Trichoderma spp., Mycogone spp., Lecanicillium spp., Cladobotryum spp., Coprinus spp., Sependonium spp., Sclerotium rolfsii, and Cephalothecum roseum among many, are found to infect mushroom crops at different stages from spawn run period to maturation of fruiting bodies. These contaminants may reduce yield and/or degrade the quality of fruiting bodies of the mushroom causing economic losses. These contaminants are usually peculiar in terms of their symptomatology on the substrates, disease cycle, epidemiological requirements, and yield losses. Most of these contaminants come from poorly sterilized substrates. Several sterilization techniques like steam sterilization, hot water sterilization, alkalinization, bleaching, and chemical sterilization can be employed to eliminate pre-existing contaminants and each technique has its own relative advantage over others. Besides, biological control involving botanicals and live antagonists can also be used as prophylactic sterilant or as therapeutic sprays. Biological control measures are friendly to the environment and human health. Unlike chemical fungicides (used as sterilant or spray), biological control measures don’t inhibit mushroom mycelial growth and even don’t raise the problem of pesticide resistance in pathogens. Roguing out of infected mushroom fruiting bodies or beds, mushroom house sanitation, and management of vector population are also equally important in preventing the spread of the fungal diseases of mushrooms. \u0000Int.

Somatic chromosome number determined for this taxon were 2n=28, haploid chromosome number n=14 and pollen fertility found to be 84.4 percent in the present study. In karyotype analysis chromosome length ranged from 0.4 to 2.6 μm and mean length was 1.5 μm. Likewise, absolute length found to be 21.9 μm and karyotype formula obtained was M16+m4+ sm8. Three types of chromosomes centromere at middle point, at median region and at sub –median region were observed. Meiosis with regular and irregular behaviors was observed in this study. The variations in chromosome numbers, irregularities in meiotic behaviors, variations in karyomorphological structure and high fertility rate shows evolve nature of this species which play a great role in evolution.

For instance, the aqueous extract of Ajwa dates (Phoenix dactilyfera) has been found to improve liver function through the restoration of anti-oxidant enzymes, liver enzymes, and cytokines balance and gene expression to normal levels. As the treatment and prognosis of Hepatocellular carcinoma, one of the leading causes of cancer associated deaths globally, has been found to be better if the liver function of the patient can be preserved, Ajwa date extract has been used together with the conventional therapeutics for the treatment of this disease. However, no study has been conducted so far on the anticancer activity of Bangladeshi wild date palm fruits (Phoenix sylvestris) despite the fact that it contains apigenin, quercetin, glucans, luteolin, and iron and vitamin complex. Therefore, in this review we discussed an idea that potential anticancer agents can be isolated from the extract of these fruits, which can eventually be used as an indigenous substance for the treatment of Hepatocellular carcinoma in our country and also the liver cancer inhibitory effects of the aqueous extract of these dates can be evaluated in rat model.","PeriodicalId":13876,"journal":{"name":"International Journal of Applied Sciences and Biotechnology","volume":"90 1","pages":"32-37"},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76015690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It contains bioactive phytochemical sesquiterpenoids, 2 (-2-phenylethyl)-4H-chromen-4-one derivatives, genkwanins, mangiferins, cucurbitacins, other terpenoids and phenolic acids. Many pharmacological studies have been performed on anti-allergic, anti-cancer, anti-inflammatory, anti-microbial, anti-diabetic, anti-oxidant, etc. The aromatic properties of agarwood when burned or distilled are extraordinary and there is high demand for the resinous wood to make incense, perfume and as traditional medicine. Aquilaria are native to northern India but over harvesting of this tree as well as other forest trees in the past has ravaged the hill country. With new technology that has been developed to induce agarwood in trees, it is now possible to produce a sustainable high valued agarwood in young plantation trees. The growing of Aquilaria in the hill agroecosystems of Nepal and cultivation of agarwood as a crop using new technology could provide a new economy for the region.","PeriodicalId":13876,"journal":{"name":"International Journal of Applied Sciences and Biotechnology","volume":"36 1","pages":"23-31"},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91364758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
