Tuesday, October 26th 2021 on 08.30 – 10.00 West Indonesian Time, Agricultural Science Doctoral Study Program, Faculty of Agriculture, Sebelas Maret University and Faculty of Science and Technology, University of Darussalam Gontor have held an event called General Lecture Word Class University Program with the title “STOP1 Regulatory Mechanism; A Master Transcription Factor for Stress Tolerance of Higher Plants”. The lecturer were Prof. Dr. Hiroyuki Koyama from Gifu University, Japan. The lecture opened with Niken Trisnaningrum, M.Si as the moderator and the opening marks from Haris Setyaningrum, S.Si., M.Si as the Dean of Faculty of Science and Technology, University of Darussalam Gontor.
The event continued by lecture from Prof. Dr. Hiroyuki Yokohama by explaining about Pleiotropy, the phenomenon in which a single gene contributes to multiple phenotypic traits. Therefore, a mutation in a pleiotropic gene may have an effect on several traits simultaneously due to the gene coding for a product used by a myriad of cells or different targets that have the same signaling function. In crops, master transcription factor control expression of “genes” that regulate crops stress tolerance and STOP1 is a typical master transcription factor that regulates various stress tolerance traits in crops. The zinc-finger transcription factor STOP1 regulates various stress-tolerance genes in Arabidopsis sp. He stated that there were several function of STOP1 for Arabidopsis such as in roots for regulating Al and H tolerances, in shoots regulating the cytosolic pH, and the major target of STOP1 in roots, ALMT1, is a key protein controlling its pleiotropic effects.
This topic were very insightful for the participants so the discussion goes on very well between Prof. Dr. Yokohama and the participants. There were total of 114 participants that attended this lecture. This event expected to increase participants’ knowledge about the use of STOP1 for stress tolerance in higher plants.
