The heat is on: maize pollen development after a heat wave

The yield of key food crops (i.e., wheat [Triticum aestivum], rice [Oryza sativa], maize [Zea mays], and sorghum [Sorghum biocolor]) relies on their production of seeds, while the propagation of almost all crops is seed-dependent. Seed set in turn relies on the production of flowers containing the male…

OsKNAT7 bridges secondary cell wall formation and cell growth regulation

The plant cell wall is a complex structure composed of cellulose embedded in a matrix of polysaccharides (hemicellulose and pectin), phenolic compounds and proteins. The primary cell wall is a thin layer formed in growing cells and is present ubiquitously, whereas the secondary cell wall is a rigid and…

Purple is the New Orange: Anthocyanin Regulation Coming Together in Carrot

Western cultivated carrot (Daucus carota subsp. sativus L) is broadly known for its orange pigmentation and accumulation of carotenoids, known as the carotene group (var. sativus). However, the eastern wild carrot (subsp. carota) originating from southwestern Asia over a century ago provides purple pigmentation…

Seeing the Cell Wall in a New Light

Sidney L. Shaw Dept. of Biology (and Physics), Indiana University, Bloomington, IN 47405 sishaw@indiana.edu   How cell expansion is controlled to achieve a specific cell morphology remains one of the frontier questions in plant biology.  The carefully guided extension of the plant…

Buffering lipid synthesis by conditional inhibition

Author: Trevor H. Yeats, Email: thy6@cornell.edu Plant Breeding & Genetics Section, School of Integrative Plant Science, Cornell University, Ithaca NY USA (Commentary on Liu et al.) Lipid synthesis is a ubiquitous, but costly branch of primary metabolism in plants. All cells must make…

Liguleless1, a conserved gene regulating leaf angle and a target for yield improvement in wheat

A major challenge in modern agriculture is to increase crop yield with diminishing agricultural land to feed the fast-growing global population. The erect leaf phenotype is a highly desirable trait that allows for higher planting density and maximizes light interception capacity and thus increases photosynthetic…

Enhancing wheat Rubisco activase thermostability by mutagenesis of conserved residues from heat-adapted species

Maria Grazia Annunziata Max Planck Institute of Molecular Plant Physiology, 14476 Potsdam-Golm, Germany. Annunziata@mpimp-golm.mpg.de ORCID ID: 0000-0001-8593-1741 Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) is the central enzyme of photosynthetic carbon assimilation in the…

Burying your head in the sand: heading belowground to find future targets of selection in roots

Author: Skelton, Robert Paul skelrob@berkeley.edu Institution: Department of Integrative Biology, University of California Berkeley, Berkeley, CA, 94720. Burying one’s head in the sand is usually synonymous with avoiding an issue, but in this volume of Plant Physiology Colombi et al. (2019)…
