You are a geneticist working on a newly discovered plant species,Florapulchra elegans. Youve identified a novel gene, SRF1, that controlswhether the plant produces flowers in response to stress. The expression ofSRF1 is regulated by:- Regulator A (RA): A transcription factor that binds to a sequence in theSRF1 promoter when active.- Histone Modifications: Acetylation near the promoter correlates with geneactivation.- Environmental Signals: High salinity stress activates RA.-You are tasked with solving the mystery of how SRF1 is regulated underdifferent conditions based on the following data observed:Experiment Conditions HistoneAcetylationRABindingSRF1ExpressionFlowersproducedWild-type no stress low no no noWild-type salinity stress high yes yes yesRA knockout mutant salinity stress high no no noHistone deacetylase mutant no stress high yes yes yes1. Based on the data, what conditions are necessary for SRF1 expression?
