How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
My research interest is to study the origins of root architectures diversity in crops. By combining knowledge from biology, statistics, and computer science: (1) I develop a computing pipeline to describe and measure the diversity of root architectures using mathematical shape descriptors. (2) I dissect the genetic components that regulate root architectures under water-limiting and drought conditions.

Natural ecosystems and agricultural production have been threatened by multifaceted global environmental changes. Soil degradation, extreme drought and flooding events, shifting climatic patterns and other challenges have prompted many disciplines within plant science to pivot to find solutions. Accordingly, root research has expanded from fundamen...

Root phenotyping describes methods for measuring root properties, or traits. While root phenotyping can be challenging, it is advancing quickly. In order for the field to move forward, it is essential to understand the current state and challenges of root phenotyping, as well as the pressing needs of the root biology community. In this letter, we p...

Roots impact plants’ capacity to absorb water and nutrients and thus play a vital role in tolerance to drought, salinity, and nutrient stress. In tomato ( Solanum lycopersicum ) breeding programs, wild tomato species have been commonly used to increase disease resistance and fruit quality and yield. However, tomato has seldom been bred for water/nu...


Questions (2)
I am now learning to find the SNPs between two tomato species based on the sequence data. However, I can not find the download-able data about it. I have tried sol genomics, it seemed that we just only could view the data online. 
My tomatoes that grow in sand are not healthy, the leaves are yellow. I have applied half a teaspoon of 20-20-20 water soluable fertilizer everyday, but it was still yellow. However, after I added 1 teaspoon of fertilizer, they are seemed burned. Please see the attached photo. Do I need to add more fertilizer?
