I would start by checking if studies in expression profiles have been done on the same materials like tomato sitiens ABA deficient types described by Stephen Groot, http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1080569/. The family of TF factors sensitive to ABA involves 10% of the whole set, and is diffcult to give a selective answer, http://www.ncbi.nlm.nih.gov/pubmed/21416314.

During seed germination its the balance between ABA and GA that matters during seed germination and GA counteracts the activity of ABA during seed germination. Check these documents 

The trascription factors that are regulated during germination and stomatal sensitivity involve several functions and loci. Shall we be aware of the difference between effects and effectors, as when external GA supply does not generate germination or transpiration ehancement. http://www.ncbi.nlm.nih.gov/pubmed/16247556

Dear Akila Wijerathna Yapa!

Concerning your question I would like to recommend to you list of most interest articles devoted to this problem. You can see these articles on-line according to references:

I hope on your interest to these works and I hope that these works will help to answer on your question.

Sincerely yours, ScD Victoria Tsygankova

Usually the role of ABA is negative and GA is positive for seed germination. The ratio between these two phytohormone is important. However, ABA is important for embryo maturation after harvest of the seed in this sense its role is positive. Regarding stomata, ABA almost always induces stomatal closure, while there are some situations that induce stomatal malfunctioning which prevent suitable response of stomata to ABA and drought stress. The DELLA protein is in the central position for the action of ABA and GA in their responses.
