About

Shawn Kaeppler is a Professor in the Department of Plant and Agroecosystem Sciences at the University of Wisconsin-Madison. His research focuses on genetics and breeding, with current interests in maize including lignocellulosic biofuel, abiotic stress tolerance, epigenetics, and seed development and composition using genetic and genomic analysis. He also conducts genomic research in switchgrass to support the development of cultivars for biofuels.

• The importance of dominance and genotype-by-environment interactions on grain yield variation in a large-scale public cooperative maize experiment

  G3 Genes Genomes Genetics · 2021 · 101 citations

  High-dimensional and high-throughput genomic, field performance, and environmental data are becoming increasingly available to crop breeding programs, and their integration can facilitate genomic prediction within and across environments and provide insights into the genetic architecture of complex traits and the nature of genotype-by-environment interactions. To partition trait variation into additive and dominance (main effect) genetic and corresponding genetic-by-environment variances, and to…

• Utility of Climatic Information via Combining Ability Models to Improve Genomic Prediction for Yield Within the Genomes to Fields Maize Project

  Frontiers in Genetics · 2021 · 92 citations

  Genomic prediction provides an efficient alternative to conventional phenotypic selection for developing improved cultivars with desirable characteristics. New and improved methods to genomic prediction are continually being developed that attempt to deal with the integration of data types beyond genomic information. Modern automated weather systems offer the opportunity to capture continuous data on a range of environmental parameters at specific field locations. In principle, this information…

• Root angle in maize influences nitrogen capture and is regulated by calcineurin B‐like protein <scp>(CBL)</scp>‐interacting serine/threonine‐protein kinase 15 (<scp><i>ZmCIPK15</i></scp>)

  Plant Cell & Environment · 2021 · 89 citations

  Crops with reduced nutrient and water requirements are urgently needed in global agriculture. Root growth angle plays an important role in nutrient and water acquisition. A maize diversity panel of 481 genotypes was screened for variation in root angle employing a high-throughput field phenotyping platform. Genome-wide association mapping identified several single nucleotide polymorphisms (SNPs) associated with root angle, including one located in the root expressed CBL-interacting serine/threon…

• Chromosome-level genome assembly of a regenerable maize inbred line A188

  Genome biology · 2021 · 83 citations

  BACKGROUND: The maize inbred line A188 is an attractive model for elucidation of gene function and improvement due to its high embryogenic capacity and many contrasting traits to the first maize reference genome, B73, and other elite lines. The lack of a genome assembly of A188 limits its use as a model for functional studies. RESULTS: Here, we present a chromosome-level genome assembly of A188 using long reads and optical maps. Comparison of A188 with B73 using both whole-genome alignments and…

• Assessing the Viability of Recovery of Hydroxycinnamic Acids from Lignocellulosic Biorefinery Alkaline Pretreatment Waste Streams

  ChemSusChem · 2020 · 75 citations

  Invited for this month's cover is the research team from the D.O.E. Great Lake Bioenergy Research Center (GLBRC) at the University of Wisconsin-Madison. The cover image shows how a diverse team with expertise in many different fields works together in an integrated fashion to address complex problems. Only when the whole system, from field to the liquid fuels and co-products, is assessed, can we identify the key parameters needed to design an economically viable biorefinery-based economy. Cover…
