Gramene (www.gramene.org) is a curated, open-source, integrated data resource for comparative functional genomics in crops and model plant species. It launched 20 years ago and has continually grown and expanded to incorporate new tools and resources. This update by Tello-Ruiz et al. describes its…

Rubisco is a major enzyme in assimilating CO2 during photosynthesis. The efficiency of CO2 assimilation is compromised by a low ratio of CO2/O2, especially in C3 plants like rice, wheat and soybean. Algae sequester Rubisco as a condensate in a microcompartment called a pyrenoid within the chloroplast…

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…

Auxin transport during development or wound regeneration is known to require auxin-induced channel or ‘canal’ formation that includes polar localization of PIN auxin transport proteins. Hajný and colleagues have characterized a receptor-like kinase (RLK) complex involved in auxin-induced pattern…

Many people are familiar with the popular houseplant Cephalocereus senilis, which also known as old man cactus because it is covered with long white hairs that are thought to protect it from frost and UV light. A similar function is described for the wooly fibers that cover the alpine plant Dionysia…

Insect-induced galls are abnormally patterned plant organs that provide insects with protection and a nutrient source, yet mechanisms underlying the development of these unique organs are mostly unknown. To identify insect factors that govern gall pattering, Korgaonkar et al. turned to the natural variation…

Plant communities seem to be able to mitigate the effects of climate and land-use change, given their responses are usually observed long after environmental conditions have changed. This lagged response has been attributed to the presence of persistent soil seed banks. Still, the evidence of their…

Review: Homoeologous exchanges, segmental allopolyploidy, and polyploid genome evolution Polyploidy or whole-genome duplication (WGD) is an important process in plant evolution and speciation. Additional sets of chromosomes can be derived from intraspecific genome duplication (autopolyploidy) or…
