Hello Everyone,
Please join us Today for this week's Enviro-Lunch talk by Jing Yan from University of California, Merced, at 12-1pm in room SE2-224.

Can plant root hydraulic redistribution help plants extract nutrients from the dry soil patches?

Abstract: Hydraulic redistribution (HR) is a natural adaptation mechanism that plant roots transfer soil moisture from wet soil layers to drier ones during night time when transpiration becomes low. While HR has attracted much research attention in global water circulation, limited research has been conducted to elucidate its role in nutrient cycling and uptake. In this presentation, I will present our recent findings of HR-aided plant self-regulation of water and nutrient availability in soil systems from a greenhouse experiment. Our results demonstrate that: (1) plants are capable of integrating multi-level information of local environmental conditions and providing complex feedbacks, e.g. initialization of HR, to sustain environments with limited resources; (2) heterogeneity in rhizosphere nutrient and moisture distribution significantly regulates plant growth behaviors and HR occurrences through changing root architecture, morphology and rhizosphere soil aggregation. The presentation will welcome and promote discussions from different scientific disciplines and perspectives focusing on the mechanistic understanding of plant root plasticity and ecological implications in ecosystem services management.

Bio: Jing Yan is an environmental soil physicist by training. He is broadly interested in developing basic and applied research of soil physics to promote food, water security and healthy ecosystem services. He gained his Ph.D. degree in Plant and Soil Sciences from University of Delaware in 2016. After graduation he joined University of California, Merced, for his postdoctoral training. His postdoctoral research is under the direction of Dr. Teamrat Ghezzehei, mainly focusing on rhizosphere nutrient and water dynamics. In addition to performing research, at the University of California, Merced, he actively promotes an interdisciplinary research community through serving as Enviro-Lunch seminar-series organizer. He is also currently elected as the postdoctoral fellow in Environmental Systems, Ecology, & Evolution, and serves as an ambassador to unite different scientific disciplines and graduate programs.

When: Today 3/21, 12pm – 1pm

Where: SE2-224

Coffee will be provided, please bring your own mugs.

We look forward to seeing you,

Jing & Jennifer
