During domestication of maize, one of the favorable traits was meristem size. Understanding the genetic circuit of maize meristem development and engineering for crop productivity are important from an agricultural perspective. In this article, Lie et al. used CRISPR-Cas9 to edit the promoter regions…

Martinez et al. use laser capture microdissection and transcriptomic sequencing to explore how gene expression patterns regulate early morphogenesis of the compound tomato leaf. http://bit.ly/3nehiZu  By Ciera Martinez, University of California, Berkeley Neelima Sinha, University of California,…

Parasitic plants form haustoria, which are specialized multicellular structures that penetrate into their host’s vasculature and act as conduits for nutrients.  The molecular and genetic contributors to haustorium development and function are well described. Here, Masumoto et al. have provided new…

Auxin shapes the plant body and drives the formation of lateral organs such as roots and ovules. In the current model, AUXIN RESPONSE FACTORs (ARFs) are transcription factors that regulate plant growth by activating signaling in an auxin dose-dependent manner, regulated by Aux/IAA proteins. Here,…

Photosynthesis, in addition to generating ‘food’ for plants, is also known to control root growth, although the mechanism has been unknown. Duan and co-workers identified CYCLOPHILIN38 (CYP38) as necessary for photosynthesis-mediated lateral root (LR) emergence. The chloroplast-localized CYP38 is…

Three-dimensional (3D) growth was an essential evolutionary innovation that allowed the radiation and diversification of land plants. In most land plants the transition from two-dimensional (2D) to 3D growth takes place during embryo development and its disruption results in lethality, however, the…

CLE40 induces localized root Ca2+ transients through CNGC9 Growth and differentiation of cells in the meristematic region are tightly regulated by different signaling pathways. In the root meristem, the small peptide CLE40 acts as a ligand that binds to cell surface receptors and regulates cellular…
