Determining the pH of Salt Solutions04:08

Determining the pH of Salt Solutions

The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution.  In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7. For...

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Root-Mediated Endophytic Colonization of Beneficial Bacteria in Rice

Begin with rice seedlings pre-germinated under dark, aseptic conditions to ensure uniform sprouting.Transfer these seedlings to a flask containing a nutrient-rich, semi-solid medium pre-inoculated with a test bacterium.As the plant grows, the roots release chemotactic compounds into the surrounding medium.These compounds stimulate bacterial proliferation, leading to adhesion, multiplication, and colony formation on the root surface.As the roots develop, the bacteria enter the plant through...

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Posterior Semicircular Canal Approach for Inner Ear Gene Delivery in Neonatal Mouse

In this study, we describe the posterior semicircular canal approach as a reliable method for inner ear gene delivery in neonatal mice. We show that gene delivery through the posterior semicircular canal is able to perfuse the entire inner...

Treatment of Bacteria with Plant Root Exudates to Emulate In Vitro Plant-Microbe Interactions

Source: Yi, Y., et al. Plant-Microbe Interaction: Transcriptional Response of Bacillus Mycoides to Potato Root Exudates. J. Vis. Exp. (2018)This video demonstrates the preparation and treatment of Bacillus mycoides cultures to study plant-microbe interactions. It outlines the steps from streaking a stock culture and incubating it in liquid medium to exposing the bacteria to plant root exudates under agitation. The process culminates in harvesting and flash-freezing the bacterial cells for...
