DESCRIPTION:Speakers: Caroline Henry (Donald Danforth Plant Science Center
 )\nIn the face of climate change and the demand for more sustainable alter
 natives to industrial operations\, duckweed plants are utilized across a d
 iverse set of applications – from wastewater treatment\, to feedstock pr
 oduction\, to bioenergy and bioproduct generation. The *Wolffia* genus is 
 the smallest and fastest-growing known angiosperm\, making it of particula
 r interest for duckweed research\, as well as plant biology more broadly. 
 With these plants becoming more relevant under an increasingly volatile cl
 imate\, it is crucial to understand stress susceptibility of these plants.
  Here we examine early salt stress response in *Wolffia australiana* plant
 s over time and under different degrees of salt stress. We examined the ph
 enotypic effects of different salt concentrations (0mM\, 50mM\, 100mM\, 15
 0mM) on growth rate and chlorophyll content. All concentrations of salt st
 ress resulted in decreased growth rate compared to the 0mM control\, as we
 ll as a persistent increase in chlorophyll content. Given that 100mM produ
 ced the clearest stress phenotype without being lethal to the plants\, we 
 assessed transcriptomic response at this concentration via bulk RNA-sequen
 cing over a 48-hour timecourse\, which identified specific genes\, gene fa
 milies\, and functional pathways involved in response to salt stress. Gene
 s upregulated under stress tended to be enriched in metabolic processes an
 d stress response\, whereas downregulated genes were enriched in reproduct
 ive and biosynthetic processes. This study will provide important insights
  into the mechanisms of salt stress response in *Wolffia*\, and how they d
 iffer from other plants.\n\nhttps://indico.unina.it/event/117/contribution
