Adamski et al. reveal that the expression of a MADS-box transcription factor is the basis for a grain phenotype observed in Polish wheat. Plant Cell https://doi.org/10.1093/plcell/koab119 By Cristobal Uauy and Nikolai M Adamski John Innes Centre, Norwich NR4 7UH, United Kingdom Background:…

The three most widely adopted plant models all use C3 photosynthesis, but discoveries made in these plants are not always applicable to C­4 plants. Foxtail millet (Setaria italica) has been emerging as a potential C4 model species, but its use for genomics research is challenging due to long generation…

Raxwal et al. uncover the roles of the RNA helicase and ATPase UPF1 in regulating gene expression. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00244   By Vivek K. Raxwal and Karel Riha  CEITEC Masaryk University, Brno, Czech Republic   Background: Gene expression, i.e., the…

Transgene introduction has been a major tool in modern plant science, but the ability of plants to distinguish ‘self’ from ‘non-self’ can lead to transgene silencing. This mechanism is mediated by the recruitment of RDR6 (an RNA-Dependent RNA polymerases) leading to the production of several…

Roots have many specialized cells arranged in concentric circles that are functionally homologous among various plant species but with varying cell-type-specific developmental programs. To further understand these developmental programs, Kajala et al. performed TRAPseq (Translating Ribosome Affinity…

The ability to directly sequence RNAs (RNA-seq) has revolutionized our understanding of gene expression, but it can miss or underestimate short-lived RNAs. Several methods have been developed to identify newly-synthesized mRNAs to provide a snapshot of transcription as it happens. Szabo present Neu-seq,…

Brumos and Zhao et al. developed an improved set of genetic tools to make precise sequence modifications in large DNA fragments and used them to tag hundreds of plant genes, including those involved in auxin production. Plant Cell https://doi.org/10.1105/tpc.19.00431 By Javier Brumos, Anna Stepanova,…

Xiang et al. elucidate transcriptome dynamics and gene activities during embryogenesis and grain development in modern wheat and its progenitors. Plant Cell https://doi.org/10.1105/tpc.19.00397. By Daoquan Xiang, Teagen D. Quilichini, Peng Gao, and Raju Datla Aquatic and Crop Resource Development,…
