The genetic basis of epigenetic variation and its consequences for adaptation
Curr Opin Plant Biol. 2023 Jul 12;75:102409. doi: 10.1016/j.pbi.2023.102409. Online ahead of print.ABSTRACTRecent population genomic studies in plants have shed new light on natural epigenetic variation by identifying key genetic determinants, "trans modifiers," that influence epigenetic states genome-wide and their interplay with environmental factors. Here, we review this progress by focusing on the epigenetic control of transposition and life-cycle transitions to highlight the ecological consequences of this genetic architecture and its evolutionary significance. This knowledge provides new opportunities to address long...

The sporophyte-to-gametophyte transition: The haploid generation comes of age
Curr Opin Plant Biol. 2023 Jul 11;75:102416. doi: 10.1016/j.pbi.2023.102416. Online ahead of print.ABSTRACTFlowering plants alternate between two multicellular generations: the diploid sporophyte and haploid gametophyte. Despite its small size, the gametophyte has significant impacts on plant genetics, evolution, and breeding. Each male pollen grain and female embryo sac is a multicellular organism with independent gene expression, a functioning metabolism, and specialized cell types. In this review, we describe recent progress in understanding the process in which the haploid genome takes over expression from its diploid ...

HD-Zip IV transcription factors: Drivers of epidermal cell fate integrate metabolic signals
Curr Opin Plant Biol. 2023 Jul 11;75:102417. doi: 10.1016/j.pbi.2023.102417. Online ahead of print.ABSTRACTThe leaf epidermis comprises the outermost layer of cells that protect plants against environmental stresses such as drought, ultraviolet radiation, and pathogen attack. Research over the past decades highlights the role of class IV homeodomain leucine-zipper (HD-Zip IV) transcription factors (TFs) in driving differentiation of various epidermal cell types, such as trichomes, guard cells, and pavement cells. Evolutionary origins of this family in the charophycean green algae and HD-Zip-specific gene expression in the ...
