This set of Agricultural Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Genetic Engineered Resistance against Fungal Pathogen”.
1. What is the full form of RIP?
a) Ribosome informing protein
b) Ribosome inactivating protein
c) Ribosome inactivating pathogen
d) Ribosome informing pathogen
View Answer
Explanation: The Ribosome inactivating proteins do not interfere with the functioning of self-ribosomes but exert inhibitory activity towards fungal ribosomes. When RIPs mix with endochitinase, the antifungal activity exhibits synergistic increase in invitro assay.
2. Transgenic tobacco with barley type-I RIP gene shows increased resistance to R. solani.
a) True
b) False
View Answer
Explanation: Transgenic tobacco with barley type-I RIP gene and potato Wun-I promoter showed an increased resistance to R. Solani. Antifungal activity exhibits synergistic increase in invitro assay.
3. What is the disease caused by Pseudomonas syringae?
a) Brown spot
b) Late blight
c) Wild fire
d) Infectious routes
View Answer
Explanation: Pseudomonas syringae causes wild fire. Alternaria longipes causes brown spot. Phytophthora infestans causes late blight.
4. Which of these is a resistant gene for Rhizoctina solani?
a) Acetyl Transferase gene
b) Citinase gene
c) Chitinase gene
d) Osmotin gene
View Answer
Explanation: The resistance gene for Pseudomonas syringae is Acetyl Transferase gene. The resistance gene for Alternaria longipes is Citinase gene. The resistance gene for Rhizoctina solani is Chitinase gene. The resistance gene for Phytophthora infestans is Osmotin gene.
5. The source of Osmotin gene is potato.
a) True
b) False
View Answer
Explanation: Phytophthora infestans causes a disease called late blight. The resistance gene for this is Osmotin. The source of gene and transgenic crop is potato.
