Investigating how floods and pests challenge tomato vitality 

 

In the University of Illinois' rooftop laboratory, Professor Esther Ngumbi conducts crucial research on tomato plants.  

Her focus is to Understand how these plants cope with flooding—a rising concern due to climate change—and subsequent attacks by pests such as caterpillars.  

This study involves two tomato varieties, Cherokee purple and striped German, which are observed for their response to these stresses in terms of gene expression and emission of volatile compounds. 

Ngumbi's research highlights how flooding profoundly affects plant physiology, more so than pest attacks. Flooding disrupts essential processes like photosynthesis and oxygen absorption, leading to weakened plant defenses.  

This makes the plants more susceptible to diseases and pests, complicating efforts to breed climate-resilient crops. 

The findings stress the importance of addressing flood impacts in agricultural research and development.  

As global temperatures rise, increasing flood frequency, understanding and mitigating these effects become crucial for securing future food supplies and maintaining crop diversity and resilience.
