Pattern formation in multicellular organisms is the result of coordinated cell division and cell fate determination. In animals, cell fate is determined mainly by a cell lineage-dependent mechanism, whereas positional information is thought to be the primary determinant of cell fate in plants. Currently,…

Secondary growth from the vascular cambium, a lateral meristem, increases the plant’s girth. It also produces wood (secondary xylem) and important fibers like flax, jute and hemp (secondary phloem). Ragni and Greb review secondary growth in plants. They start with a review of the evolutionary history…

Plants are known for their ability to regenerate tissues following wounding. Wound repair requires the induction of cell proliferation, leading to the formation of undifferentiated callus at the wound site, followed by cell differentiation. Ikeuchi et al. explored transcriptional changes following wounding…

This issue is rooted in the 37th New Phytologist Symposium on ‘Plant developmental evolution’, 2016, that gathered researchers working on the developing field of plant evo-devo. The issue is a wonderful compendium of work presented during the symposium and the contribution of other researchers working…

The mystery of asymmetry is a fundamental question in biology. Plants produce asymmetric shapes in many organs e.g., primordial cells on the leaf epidermis which undergo asymmetric divisions to define stomatal stem cells that ultimately form mature stomata. This asymmetric polarity of cells is governed…

The phytohormones auxin and cytokinin (CK) work either antagonistically or synergistically to regulate several critical development pathways such as meristem formation and maintenance. Müller et al. show similar crosstalk between auxin and CK in controlling early gynoecium patterning. Using TCSn::GFP…

Tenreira et al. find a gene responsible for the differentiation of the stolon in strawberry. The Plant Cell 2017. https://doi.org/10.1105/tpc.16.00949 Asexual reproduction produces offspring that are genetically identical to the parents. This process takes many forms in flowering plants, including…

Su et al. look at chromatin modifications that affect flowering. The Plant Cell 2017. https://doi.org/10.1105/tpc.17.00266 Plants, unlike animals, begin their lives as seeds that – in flowering plants – develop from flowers. This depends upon proper regulation of flowering time, to ensure pollination,…
