Abscisic acid (ABA) is a phytohormone that plays an important role in plant growth and in the response to environmental challenges. A recent study in Plant Cell shows that certain chloroplast proteins can function as a receptor for Abscisic acid (ABA) in Arabidopsis Thaliana and that they interact with transcription factors acting as regulators of development. The study has been carried out using anti-Psbe, anti-Hcf101, and anti-Toc34 antibodies that are available on antibodies-online.
