Transport of plant growth promoting bacteria
Azospirillum brasilense strains Sp7 and Cd are commonly employed plant growth-promoting bacteria (PGPB) that produce phytohormones and fix nitrogen. The two basic methods of PGPB soil inoculation are direct mixing with the soil and irrigation with liquid inoculants. The integration of drip irrigation with delivering plant growth-promoting bacteria in desert areas with …

How is Sugar Transported in Phloem?
Sugar, primarily in the form of sucrose, RFOs (Raffinose family oligosaccharides), and polyols, is transported within the phloem through specialized cells called sieve tubes.. Here's a breakdown of the process: Loading into Sieve Tubes: At the source, such as leaves, sugars are actively loaded into the sieve tube elements. This process often requires energy, as sugars …

How water and minerals are transported in plants?
Water and minerals are transported through the soil to the leaves through xylem cells. The xylem cells of roots stem and leaves are interconnected to form a conducting channel reaching all plant parts. The root cells take ions from the soil. This creates a difference between the concentration of ions in roots and soil.
