Abstract The study was conducted to evaluate the growth and yield response of M20 with the application of Nostoc and to determine the ideal combination of inorganic fertilizer and Nostoc. Based on the result of the study, in terms of growth parameters; application of 3 g Nostoc with 1/2 RRIF gave the best response among the treatment in plant height, while application of 3 g Nostoc with 3/4 RRIF was the best treatment when it comes to days to flowering. Furthermore, the application of full RRIF was the best in terms of chlorophyll content. In yield parameters, the application of 3 g Nostoc with 1/4 RRIF gave significance response to grain yield and biomass. While the application of no Nostoc with 1/4 RRIF had the heaviest 1000 grain weight. For the number of tillers per plant (14.7), the application of 3 g Nostoc with 3/4 RRIF gave the best response among the treatments. And for the number of filled grains, rice grown without Nostoc but fertilized only with 1/2 RRIF had the most number of filled grain. Overall, Nostoc treatment did not significantly alter the response of M20 based on all agronomic parameters tested in the study.

Abstract Cyanobacteria and their emissions are becoming more widely reported around the world, posing a serious threat to both the environment and human health. Several orders of cyanobacteria have been identified to make cyanotoxin, the most common algal toxin. The aim of this research was to develop a method for detecting cylindrosprmopsin and saxitoxin biosynthesis genes in rivers .In November, December 2019 and January2020. Cyanobacteria were isolated from Tigris River freshwater and detected using a compound microscope as well as traditional PCR .All cyanobacteria isolates contained phycocyanin gene fragment. Five isolates of cyanobacteria in these study was successfully amplified a phycocyanin gene (Microcystis flosaquae, Microcystis sp, anabaena circinalis ,nostoc commune and westiellopsis prolifica) and all isolates successfully amplified aoaC gene to detecting the cylidrospemopsin and the saxitoxin. Our findings show that a PCR assay can be used to detect cylidrospemopsin and saxitoxin-producing cyanobacteria in river water, which is useful for stations that prepare drinking water for the public.

Abstract Nostoc commune Vauch is a nitrogen-fixing blue-green algae, contains a large number of active molecules with medicinal functions. Our previous study found that a water stress protein (WSP1) from Nostoc commune Vauch and its the recombinant protein (Re-WSP1) exhibited significant anti-colon cancer (CRC) activity both in vitro and in vivo. However, the underlying mechanism remains unknown. In this study, the CCK8 and clonogenic assays showed that Re-WSP1 restrained the colon cancer growth in a dose-dependent manner. Mechanistically, Re-WSP1 inhibited the expression of β-catenin, which was partly reversed by LiCl treatment, demonstrating a key role in Re-WSP1-induced inhibition of cell growth. Quantitative PCR analysis showed that the expression of microRNA-539 (miR-539) was significantly up-regulated upon Re-WSP1 treatment. Moreover, miR-539 negatively regulateed the expression of β-catenin through directly binds to the 3’UTR of β-catenin mRNA. Taken together, our data demonstrate that Re-WSP1 suppresses the CRC growth via miR-539/β-catenin axis, which provides new insights into the molecular mechanisms underlying Re-WSP1 against CRC.
