Extraction of quality RNA for molecular biology applications from perennial woody plants like mulberry is complicated due to the presence of high polysaccharides, polyphenols and other secondary metabolites. Since the existing methods failed to yield quality RNA in sufficient quantity from leaf and root tissues of mulberry, in this study, we modified the CTAB-based protocol. The standardised protocol yielded high quantity (520.00 μg/g fresh weight of leaf tissue) of quality RNA and the RNA extracted was suitable for all downstream applications such as cDNA synthesis, PCR and whole transcriptome analysis. The method developed was also found to be useful for isolating good quality and quantity total RNA from desiccated and salinity stressed leaf tissues of mulberry. The protocol was also applied successfully to isolate total RNA from leaf tissues of other species such as cardamom, papaya and rice.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
