Uncovering the genetic basis of adaptation to drought stress: Jie Xu

Jie Xu received the 2018 MAIZE-Asia Youth Innovators Award from the CGIAR Research Program on Maize (MAIZE) for her work on drought stress in maize root systems. Her work seeks to understand the genetic basis of plant adaptation to drought with a view to applying the findings to breeding drought-tolerant maize. Originally from Chengdu, in Sichuan Province, China, she is an Associate Professor at Sichuan Agricultural University. In a recent interview, she discussed the challenges and opportunities facing maize in Asia, as well as the importance of involving young women in agriculture and maize-based systems.

Q: What inspired you to pursue a career in maize-based systems?

Jie Xu is an
Associate Professor at Sichuan Agricultural University

I was born in the western rural area of China, where maize is widely cultivated, being one of our favorite crops. When I was a student in Sichuan Agricultural University, I joined the maize research institute for my bachelor’s degree in 2006 and began my maize drought tolerance research under the guidance of my mentor, Prof. Tingzhao Rong. Drought tolerance is a very complex trait – it takes us years to screen the typical tolerant/sensitive inbred lines and construct the suitable research populations.By studying the maize inbred lines, which exhibit different levels of drought tolerance, we explore their genome and transcriptome variations to understand the genetic basis of plant adaptation to drought. This knowledge can then be applied to breeding drought-tolerant maize. However, the more I learned, the more I realized how much I didn’t know and just how complex the drought-tolerance trait is.

KATHMANDU, Nepal — I feel humbled and honored to have been chosen for the 2018 MAIZE-Asia Youth Innovators Award. I want to thank my father and brother for never clipping my wings and letting me fly high. I want to thank my mother, who despite having no education, not being able to read or write a single word, dreamed of having a scientist daughter. Everyone has a story and this is mine.

Maize Needs Young People: Dinesh Panday

Dinesh Panday received the 2018 MAIZE-Asia Youth Innovators Award from the CGIAR Research Program on Maize (MAIZE) for his work in soil fertility and nutrient management to determine the effectiveness of industrial by-product (i.e., char) in reducing environmental nitrogen loss and improve nitrogen fertilizer use efficiency in maize. A native of Nepal, he is a Doctorate Graduate Research Assistant in Soil Fertility and Nutrient Management at the University of Nebraska-Lincoln. In a recent interview, he discussed the challenges and opportunities facing maize in Asia, as well as the importance of involving youth in agriculture and maize-based systems.

In 2017, 79 improved maize varieties were released by MAIZE partners worldwide, including 26 in Latin America, 44 in Sub-Saharan Africa and 9 in Asia. These varieties are based on use of CGIAR lines from the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA). Some of the special traits stacked in these varieties include drought and heat tolerance, nitrogen use efficiency, enhanced protein quality, high kernel zinc and resistance to diseases of regional or global importance, such as maize lethal necrosis (MLN), tar spot complex (TSC), and resistance to the parasitic weed, Striga.
