NEST2020BiologyPlant - Growth and Development
Gibberellins (GA) are hormones required for stem elongation and thereby the overall height of the plant. Bioactive GA binds to its receptor and subsequently activates the gene expression leading to stem growth. In the absence of GA, the SLR1 repressor blocks transcription of GA-inducible genes. GA binds to a receptor GID1 in the nucleus and the GA-GID1 complex then binds to the SLR1 repressor. Formation of GA-GID1-SL
Options
- ASLR1 RNAi plants are tall in the presence of bioactive GA 2.
- BMutation of transcriptional activator binding site on SLR1 will result in short plants even in the presence of
- CIn absence of bioactive GA, SLR1 remains bound to the transcriptional activator resulting in growth of plants
- DPlants mutant for GID1 gene result in dwarf plants even in presence of bioactive GA
Correct answer
D. Plants mutant for GID1 gene result in dwarf plants even in presence of bioactive GA
