Transcriptional repression of GTL1 under water-deficit stress promotes anthocyanin biosynthesis to enhance drought tolerance

N. A. Mano, M. A. Shaikh, J. R. Widhalm, C. Y. Yoo, M. V. Mickelbart

The paper identifies GTL1 as a negative regulator of drought tolerance, showing that its repression under water-deficit stress promotes anthocyanin biosynthesis and enhances drought tolerance.

Disruption of Zea mays isochorismate synthase1 decreases PHENYLALANINE AMMONIA LYASE activity and suppresses hypersensitive response-induced metabolism

R. L. Benke, R. M. McCoy, I. M. Ibrahim, J. P. Simpson, F. Muro-Villanueva, R. R. Zhan, C. Chapple, J. R. Widhalm, S. Puthiyaveetil, G. S. Johal, B. P. Dilkes

This study shows that disrupting Zea mays ICS1 reduces PAL activity and suppresses hypersensitive response metabolism, revealing an interaction between ICS and PAL pathways in SA biosynthesis.
