Plants are able to suppress their growth when they are in unfavourable conditions to increase survival chances. A team of researchers from CUHK, including Professor Jiang Liwen from School of Life Sciences, and South China Normal University discovered that the plant vesicular transport regulatory protein FREE1's participation in plant hormones ABA signalling not only takes place in the cytoplasm, but also in the nucleus to directly regulate it at the transcriptional level. The clues found in both gene expression and protein transport levels contribute to the theoretical basis for improving crop tolerance to environmental stresses through genetic engineering.
This important finding has recently been published in Nature Plant. Further reading: Li, H., Li, Y., Zhao, Q., Li, T., Wei, J., Li, B., ... & Zhao, Y. (2019).
