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…

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…

Keep sugar away to stay active: glycosylation of methyl salicylate shuts down systemic signaling
Plant hormones are frequently modified by glycosylation, hydroxylation, methylation and other conjugations, and these modifications can alter the hormone’s activity and stability (Wang et al., 2019). The phytohormone salicylic acid orchestrates effective defense and mediates local and systemic-acquired…
A rice transcription factor controls grain length through cell number
Providing around 20% of global calories, rice (Oryza sativa) is one of the most important staple crops (Global Rice Science Partnership (GRiSP), 2013). With consumption particularly increasing in sub-Saharan Africa, the Middle East and Latin America, it is vital to increase rice yields to supply the…
