117 Plant Physiology- ICAR JRF/SRF 2024 MCQ (Single Correct) +4 −1 What is the gene encoded by the auxB gene of T-DNA? A Indole acetamidehydrolase Correct Incorrect B Tryptophan monooxygenase Correct Incorrect C Isopentenyl transferase Correct Incorrect D Aminoglycoside adenyltransferase Correct Incorrect Check Answer EXPLANATION Plant Genetic Transformation Vectors, Agrobacterium T-DNA and Selection Auxin Biosynthesis Genes of T-DNA:auxA (iaaM): Encodes tryptophan 2-monooxygenase, which oxidizes L-tryptophan into indole-3-acetamide (IAM).auxB (iaaH): Encodes indoleacetamide hydrolase, which hydrolyzes indole-3-acetamide into active indole-3-acetic acid (IAA).Other T-DNA Genes: ipt encodes isopentenyl transferase for cytokinin synthesis. Correct option: (1) Indole acetamidehydrolase Explanation not matching this question? क्या व्याख्या इस प्रश्न से मेल नहीं खा रही? Report Mismatch त्रुटि बताएं Prev Next
