Message-ID: At the June 6 meeting, the speaker will be Dr. Caren Chang, Department of Cell Biology and Molecular Genetics, University of Maryland Her topic: Ethylene Hormone Signaling in Arabidopsis thaliana https://us02web.zoom.us/j/85140612491?pwd=eHJJTlVPYTFYQ0hYMDViKytNSW9zQT09 Meeting ID: 851 4061 2491 Passcode: 640159 Flier: http://botsoc.org/jun23.pdf The meeting will start at 7 with doors opening by 6:45. About the talk: Ethylene is a gaseous plant hormone that has profound effects on plant growth and development. Flowering plants produce ethylene from a molecule called 1-amino-cyclopropane-1-carboxylic acid (ACC). Given that ACC is much easier to work with than ethylene gas, scientists often treat plants with ACC in order to induce ethylene responses. However, recent evidence tells us that ACC can unexpectedly trigger responses in plants that are distinct from those induced by ethylene. This raises the interesting possibility that ACC itself is a signal in plants with ramifications for the use of ACC as a substitute for ethylene. Evolutionarily, we find that ACC may have served as a signal prior to acquiring its role as the ethylene precursor in seed plants. This seminar will present some of the supporting evidence we found in the liverwort Marchantia polymorpha and the small flowering plant Arabidopsis thaliana, in the context of the emerging evolutionary history of ethylene as a plant hormone. ----------------------------------------------------------- The next BSW meeting will be in September and, as has been the custom, it will be Members' Night. So mark your calendars for September 5 and think about doing a brief presentation. ------------------------------------------------------------ Can 19th century botany inspire the climate struggle of today? https://partner.sciencenorway.no/botany-climate-change-university-of-oslo/can-19th-century-botany-inspire-the-climate-struggle-of-today/2205495 ------------------------------------------------------------ On the Grand Canyon Botanists That History Erased https://orionmagazine.org/article/grand-canyon-botany-book-elzada-clover-lois-jotter/ ------------------------------------------------------------ Country diary: Heavy metal botany on the banks of the Tyne https://www.theguardian.com/environment/2023/may/19/country-diary-heavy-metal-botany-on-the-banks-of-the-tyne From kathy at fred.net Tue Jun 6 15:25:23 2023 From: kathy at fred.net (KATHY BILTON) Date: Tue, 6 Jun 2023 16:25:23 -0400 (EDT) Subject: [BSW] REMINDER: Meeting this evening at 7pm (Tuesday, June 6) + Misc.

As has been the case for quite some time for the September meetings, it will be Members' Night. Several members will be giving 5-10 minute presentations on a variety of topics. As in the past, our September "Members' Night" will provide an opportunity for several members to share some of their botanical travel or research slides, or to present other short subjects (10 minutes or less) to which this format is especially suited. Members who plan to present slides should send an email to Vice-President Mary McKenna at dr.mary.mckenna at gmail dot com. ---------------------------------------------------- Dr. Caren Chang's June 6 presentation on "ACC Signaling in Arabidopsis thaliana" is currently available using the link below. https://us02web.zoom.us/rec/share/WBmQ6EMnvvrZixXpZzT9ljKKxMWCP1F5gT4oDBGMPIDcdVqQkTyuon_f_wVrd-1C.bQ5DRKLA97zhFFFN Passcode: &hMq5ZWu --------------------------------------------------- June 21 @ 7 PM ?
