Wheat yields depend on the morphology of the inflorescence known as the spike, which harbors multiple lateral spikelets. To control and manipulate wheat productivity, it is necessary to understand the molecular and genetic mechanisms behind the development of inflorescence architecture. Wheat spike development…

Seed production was a decisive adaptation that appeared during plant evolution. Not in vain! The most diverse plant lineage today is that of the so-called seed plants, a group that includes gymnosperms and angiosperms. Therefore, it is not surprising that understanding seed origin and evolution has been…

The development of Arabidopsis as a model system greatly advanced the field of plant cell biology by bringing in molecular approaches, so much of our conceptual foundation rests on studies from angiosperms. More recently, model bryophytes, particularly Marchantia polymorpha (liverworts) and Physcomitrium…

The transition from aquatic to terrestrial habitats exposed plants to low water availability, high light, radiation, and other environmental challenges. To overcome these challenges, plants developed morpho-physiological adaptations to tolerate dry environments and make photosynthesis more efficient.…

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…

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…

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 - 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…
