Genome assembly and population genomic analysis provide insights into the evolution of modern sweet corn (Nature Comms)

In maize (Zea mays), loss of function mutations in genes involved in starch biosynthesis characterize sweet corn varieties that have increased sugar content in the kernel. Specifically, lines carrying the shrunken2 (sh2) allele revolutionized the corn industry in Northern America in the last 50 years…

Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass (Nature)

Switchgrass (Panicum virgatum) is a tall, perennial species native to the prairies of North America. Switchgrass is well-known for its uses as a biofuel and forage crop. However, switchgrass is also a fascinating model to investigate how plants adapt to changing environments, as historical glacial cycles…

Deeply altered genome architecture in the endoparasitic flowering plant Sapria himalayana Griff. (Curr. Biol.)

It’s one of those plants that gets noticed, so we’re excited to see the press associated with the genome sequence of the large endoparasitic plant Sapria himalayana. Everyone has seen pictures of this plant, which lives entirely underground except when it produces its large (20 cm diameter) blood…

Review: Orphan crops and their wild relatives in the genomic era (Mol. Plant)

More than half of human calories come from rice, wheat, and corn, although many other cereals have been domesticated as food crops. Several of these “orphan” cereal crops and their wild relatives are being studied with the goal of diversifying our food supply, which is particularly important due…

ConnecTF: A platform to integrate transcription factor-gene interactions and validate regulatory networks (Plant Physiology)

ConnecTF: A platform to integrate transcription factor-gene interactions and validate regulatory networks Gene regulatory networks (GFNs) are complex beasts, integrating multiple components of transcription factors (TFs), regulatory loci, and function -- not to mention the myriad datasets and methodologies…

Gramene 2021: harnessing the power of comparative genomics and pathways for plant research (Nucleic Acids Research)

Gramene (www.gramene.org) is a curated, open-source, integrated data resource for comparative functional genomics in crops and model plant species. It launched 20 years ago and has continually grown and expanded to incorporate new tools and resources. This update by Tello-Ruiz et al. describes its…

Multi-omics analyses of wild tomato introgression lines reveal a set of gene expression-metabolite-pathogen sensitivity interactions (Nat. Genet.)

Domesticated tomato has been subjected to human selection to satisfy marketing and economic desires, leading to a loss of genetic diversity and elimination of fruits traits such as flavor, aroma and pathogen resistance. Introgression lines (ILs) that capture the genome of wild desert-adapted tomato Solanum…

Review: Less is more, natural loss-of-function mutation is a strategy for adaptation (Plant Communications)

Gene gain through duplication and gene loss through loss-of-function (LoF) mutations determine genetic variation underlying diversification and adaptive evolution. In this review, Xu and Guo highlight the importance of LoF mutations in the evolutionary success of several organisms as revealed by advancements…

Pan-genome of wild and cultivated soybeans (Cell)

Widespread genome sequencing of individuals has revealed the high level of intraspecific variability in plant species. As such, constructing high-quality pan-genomes is a growing necessity to study dynamic plant genomes. Here, Liu et al. release the soybean pan-genome formed from sequencing 2,898 accessions,…
