Laboratory protocols for evaluating plant growth-promoting bacteria including phosphate-solubilizing bacteria (PSB) screening using Pikovskaya’s medium, colony characteristic observation, phosphorus-dissolving capacity determination via molybdenum-antimony-scandium colorimetry, nitrogenase activity measurement using acetylene reduction method, and multifunctional bacterial screening (ACC deaminase, siderophore, IAA secretion).

Foundational immunology lecture covering innate (non-specific, physical barriers, phagocytes, NK cells) versus acquired/adaptive immunity (specific, memory-based, B/T cells), types of immunity (naturally/artificially acquired active/passive), species/racial/individual immunity variations, antigen characteristics (immunogenicity, epitopes), haptens, adjuvants, and factors influencing immune response.

Detailed comparison of innate and adaptive immune responses to bacterial versus viral infections, pattern recognition receptors (PRRs/PAMPs/TLRs), phagocytosis, interferons, cell-mediated immunity, host-pathogen interaction mechanisms including bacterial/viral recognition and entry processes (zipper/trigger mechanisms, endocytosis, fusion), and plant pathogen interactions including ETI/PTI pathways.
