Principal Investigator

Wolfgang Busch

Plant Molecular and Cellular Biology Laboratory
Integrative Biology Laboratory

Wolfgang did his undergraduate studies in Biology at the University of Tübingen, Germany. During this time, he also spent 8 months at UC San Diego where he received training on computational biology and conducted research on transporter proteins. During his PhD at the Max Planck Institute for Developmental Biology in Tübingen, he identified novel key regulatory genes and modules for plant stem cell control via a systems biology approach integrating transcriptome- and genome-scale transcription factor-DNA binding data. Wolfgang received his PhD in 2008 from the University of Tübingen. During his postdoctoral training at Duke University he contributed to the discovery of spatiotemporally defined regulatory modules that control proliferation of stem cells and differentiation in the root, and used high-throughput confocal microscopy to capture dynamic features of gene expression. In 2011, he joined the Gregor Mendel Institute of Molecular Plant Biology in Vienna as a group leader. During this time, he established his research program in root systems genetics and focuses on understanding which genes, genetic networks, and molecular processes determine root growth and its responses to the environment. In 2017, he came to the Salk as an Associate Professor in the Plant Molecular and Cellular Biology Laboratory. He is also part of the Integrative Biology Laboratory. A recent key interest of Wolfgang is researching and developing plant varieties with enhanced carbon sequestration capabilities for removing CO2 from the atmosphere and thereby counteracting climate change.
Postdoctoral Fellows

Elohim Bello Bello

Postdoctoral Fellow

Elohim obtained his PhD at the National Laboratory of Genomics for Biodiversity (LANGEBIO-CINVESTAV), Mexico. During his PhD research, he contributed to the identification of genomic regions and genes associated with natural variation in primary root penetrability in Arabidopsis thaliana. His research interests are related to the implementation of multi-omics-based strategies (scRNA-seq, GWAS, MERFISH, scGRNs, etc) to understand how gravitropic and thigmotropic responses modulate root penetration into compacted soils. He seeks to decode the genetic/molecular mechanisms governing natural variation in root system penetrability to enhance rooting depth and CO2 sequestration in crop plants. Elohim joined the Busch lab in 2022 as a part of the Harnessing Plants Initiative at the Salk Institute. He and his colleagues are focused on designing new high-throughput phenotyping platforms and creating root-targeted genetic engineering solutions to develop smart-rooting crops better adapted to land degradation and climate change, which could contribute to transforming and reorienting agricultural systems towards climate-smart agriculture.
