Plants are affected by various factors including abiotic and biotic stresses in nature. Due to the recent climate changes, crop production has seriously dropped. One of the many abiotic factors that contributes to this issue is osmotic shock or osmotic stress in plants, which results from salinity, drought, and low temperature (Upadhyaya et al., 2013). Osmotic adjustment plays a significant...

Enterococci are facultative anaerobic and Gram-positive bacteria often forming normal fecal flora of humans. However, these bacteria are increasingly appearing as primary pathogens among patients with compromised immune systems (Hemalatha, Bhaskaran, Sowmiya, & Anusheela Howlader, 2017). This manifestation is believed to be due to its resistance to various antibiotics along with its ability to form biofilms and acquiring some virulence...

Bacteria is an example of a unicellular prokaryote. Several bacteria move by turning the flagellum (Kojima, 2015). Several movable bacteria move in fluid or on a firm exterior utilising their flagellum. The flagellum has a spiral shape and expands from the cell body. The flagellum’s turning movement causes the bacterial cell to swim. The rotary motor located in the inner...

Gene regulation is the way genes are expressed, and it starts with the central dogma. Gene regulation starts with the DNA which makes mRNA which then makes proteins. Prokaryotes, which are bacteria (for example E. coli), eat whatever we eat; therefore, if we drink milk, the bacteria will break down the lactose using gene regulation (Anderson, 2011). Bacterial genes are...
