Comparative profiling examines roles of DNA regulatory sequences and accessible chromatin during cold stress response in grasses
Physical access to regulatory DNA, including cis-regulatory sequences found within proximal promoters and distal enhancer elements, is a vital property of chromatin. In turn, their access is determined by nucleosome occupancy and posttranslational modification of histone proteins. A continuum of chromatin accessibility states from closed to permissive and open chromatin is a critical determinant of chromatin’s […]
The R-loop: An additional chromatin feature for gene regulation in Arabidopsis
Gene Dosage Balance Immediately following Whole-Genome Duplication in Arabidopsis
Flowering plants have witnessed multiple cycles of whole-genome duplication (WGD) over the past 200 million years of evolution. Typically, WGD increases genome size and gene content, followed by gene loss, or fractionation, depending on functional categories. Certain classes of genes are retained as duplicates for longer periods of evolutionary time. Duplicate genes provide a potential […]
Advances in plant phenomics: From data and algorithms to biological insights
The measurement of the characteristics of living organisms is referred to as phenotyping (Singh et al., 2016). While the use of phenotyping in plant biology and genetics can be traced back at least to Gregor Mendel sorting and counting peas by shape and pod color 160 years ago, addressing current questions in plant biology, genetics, and […]
