Transposable elements (TE) constitute a large percentage of the maize genome. However, traditional studies based on reference genome alignment can result in large fragments that cannot be aligned, which could be due to TE insertions. The de novo assembly of four representative maize inbreds, B73, W22,…

Single cell RNA sequencing (scRNA-seq) has transformed our understanding of gene expression within and amongst individual cells. These techniques have been applied extensively to animal cell populations to discover the development of specific cell lines and identify rare cell types but are not commonly…

Whole genome sequencing (WGS) unlocks the repertoire of genes encoded within the genome. From a structural genomics aspect, the sequence data enables the development of molecular markers and maps, and identification of novel QTLs/genes/alleles regulating the trait-of-interest. From a functional genomics…

Lack of sequence information makes harnessing the diversity of disease resistance (R) genes in wild crops highly challenging. Arora and Steuernagel et al. report AgRenSeq, a reference genome-free technique, for rapid cloning of nucleotide binding/Leucine-rich repeat (NLR) resistance genes from wild…

High-throughput plant phenotyping is growing rapidly and enables the collection of dozens or hundreds of traits of the same plant genotype efficiently. The development of this technology expands the diversity of plant phenotypes and brings an opportunity for reexamining the connections between genotype…

Biotrophic phytopathogens manipulate living hosts for the procurement of nutrients essential for growth and reproduction. It is therefore critical for invading biotrophs to evade or suppress immune responses without impacting overall plant function. In a recent study published in New Phytologist (2019),…

It’s January, which seems to be a month of weather extremes for many “temperate” parts of the globe. Here’s an excellent collection to curl up with as you try to stay warm or cool and out of the elements. The issue includes free-to-access reviews focused on using genomic data (e.g., genome-wide…

Sunflower (Helianthus annuus L.) is an important oil-producing crop, which was domisticated in North America about 4000 years ago with elite varities being developed through the 19th and 20th centuries, narrowing its genetic variation. It retains the ability to hybridize with wild relatives, providing…
