Research Overview

The development of high throughput technologies has given rise to a wealth of information at system level including genome, transcriptome, proteome and metabolome. However, it remains a major challenge to digest the massive amounts of information and use it in an intelligent and comprehensive manner. To address this question, Dr. Fei’s group has focused on developing computational tools and resources to analyze and integrate large scale “omics” datasets,” which help researchers to understand how genes work together to comprise functioning cells and organisms.

Development of online databases to facilitate data distribution, analysis, mining and integration

Development of computational tools for omics data analysis

  • Plant MetGenMAP – a web-based tool for comprehensive mining and integration of gene expression and metabolite changes in the context of biochemical pathways.
  • iAssembler – A de novo assembly package for transcriptome sequences generated using 454 or Sanger platforms
  • iTAK – A package to identify and classify plant transcription factors and protein kinases.
  • VirusDetect – An automated pipeline for efficient virus discovery using deep sequencing of small RNAs.

Application of NGS technologies and bioinformatics in crop improvement

During the past several years, significant progresses have been made regarding the DNA sequencing technologies. As a result, several next-generation sequencing (NGS) platforms, such Illumina HiSeq, have received wide applications due to their high throughput and low cost. We are interested in using NGS technologies to investigate genomes, epigenomes and transcriptomes of several economically important crops including tomato, cucurbits, sweetpotato, and fruit tree crops, to facilitate the understanding of the evolution and regulatory networks of important agronomical traits. We are also using NGS technologies to perform large-scale virus survey for crops like sweet potato and tomato, in an effort to understand global virus diversity, distribution and evolution in important food crops.

Inferring gene regulatory networks

Living cells are the product of gene expression programs involving regulated transcription of thousands of genes. How a collection of transcriptional regulatory factors associates with genes during specific biological processes or under specific environmental conditions can be described as a gene regulatory network. We are interested in developing new algorithms to infer gene regulatory networks by integrating datasets from various different sources, including gene expression data, metabolomics data, promoter sequences, and microRNA information.

  • Harvesting Genes to Improve Watermelons

    When many people think of watermelon, they likely think of Citrullus lanatus, the cultivated watermelon with sweet, juicy red fruit enjoyed around the world as a dessert. Indeed, watermelon is one of the world’s most popular fruits, second only to tomato – which many consider a vegetable. But there are six other wild species of […] Read more »
  • BTI Welcomes Summer Student Interns

  • BTI Scientists Create New Genomic Resource for Improving Tomatoes

    Tomato breeders have traditionally emphasized traits that improve production, like larger fruits and more fruits per plant. As a result, some traits that improved other important qualities, such as flavor and disease resistance, were lost. Researchers from Boyce Thompson Institute and colleagues from partnering institutions have created a pan-genome that captures all of the genetic […] Read more »
  • BTI Promotes Faculty Member Fei

    David Stern, president of the Boyce Thompson Institute (BTI), is delighted to announce that faculty member Zhangjun Fei has been promoted to Full Professor on February 27, 2019. Fei was evaluated on his achievements to date and the potential he possesses. Fei has made a name for himself as one of the world’s foremost experts […] Read more »
  • New CRISPR database to catalyze collaborations

    Recently developed gene editing tools like CRISPR/Cas enable scientists to figure out the functions of myriad plant genes. While these studies could eventually lead to the creation of crops with improved traits like increased disease resistance or higher yield, researchers first need a good way to keep track of the increasingly large amounts of resulting […] Read more »
