Questions (page 2)

Q1. Q
1. Compare the major plant immune signalling pathways involved on pathogen recognition and defence activation. Discuss recent scientific insights into the integration and crosstalk between receptor mediated Pattern-Triggered Immunity (PTI) and intracellular Effector-Triggered Immunity (ETI). Support your answer with examples of receptor types and signalling molecules illustrating how these pathways cooperate to enhance plant Immunity. Describe the historical development of genetics, highlighting key discoveries that shaped the gene and allele concepts. Q
1. (b) Explain the difference between a gene and an allele and discuss recent advancements that have expanded our understanding of these concepts. Critically analyze the methods of plant breeding, focusing on selection and Q
1. (c) Hybridization techniques such as pedigree method, back cross method, mass selection and bulk method. Discuss their principles, advantages, limitations and 10 applications in crop improvement. Describe the structure and functions of plant cell membranes with special emphasis on cell adhesion, type of membrane transport and the role of vesicular transport. Q
1. (d) Explain how these processes contribute to maintaining homeostasis and intracellular communication in plants. Describe the structure and major components of plant extracellular matrix (cell wall). Q
1. (e) Discuss its functions in plant growth, defence and intracellular communication. Highlight recent insights into cell wall remodelling and how understanding its dynamic nature can be applied in improving plant resistance and development.
