Review: Molecular mechanisms involved in functional macroevolution of plant transcription factors (New Phytol)

Transcription factors (TFs) are very important actors through which evolution can operate. In every organism and system studied, starting with the seminal work of Jacob and Monod, they’ve been shown to be potent regulatory proteins. Here, Romani and Moreno review the contributions of plant transcription…

Functional innovations of PIN auxin transporters mark crucial evolutionary transitions (Science)

Complex multicellular flowering plants evolved from simple unicellular algae. This evolutionary transition was driven by crucial innovations in plant anatomy like shoot and root, inflorescence and flowers. Multiple studies have demonstrated the role of local auxin gradients in determining the development…

Conserved transcriptional programs underpin organogenesis and reproduction in land plants (bioRxiv)

Land plant evolution accompanied a plethora of evolutionary novelties such as cells that compose complex organs (e.g., stems, leaves, roots) and male/female gametophytes. The identity and conservation of the transcriptional programs underlying organogenesis and reproductive development across land plants…

Plantae Presents Panel: Evo-devo as a discovery tool

Plantae Presents - Evo-devo. What can we learn from comparative studies? Recorded Wednesday, October 28 - 10 am EDT We're pleased to announce the second in our series of webinars that are drawn from contributed short videos, followed by a panel discussion. This week we'll look at the topic of…

Review: Gemma cup and gemma development in Marchantia polymorpha (New Phytol.)

Plants have the astounding capacity to generate new plants derived from specialized organs (i.e., roots, leaves, and stems). This capacity, known as vegetative propagation, is used by horticulturists and farmers to propagate clonal varieties. This form of reproduction is fueled by the ability to…
