Auxin signaling influences plant growth and development by controlling gene expression, often through binding of transcription factors from the Auxin Response Factor (ARF) family to ARF elements (AuxRE) present in the promoters of auxin-responsive genes. However, given that auxin signaling produces many varied effects on growth, it’s not clear how diverse responses are achieved with […]
Plants develop new organs and tissues throughout their lifespan as they grow new leaves, roots and reproductive structures. Many of these tissues arise from similar tissues, such as lateral roots arising from primary roots, and the mechanisms guiding their formation are well understood. But what about ‘trans-organogenesis’: where structures arise from completely different tissue types? The […]
While it is recognized that plant communication, both within and between plants, can be achieved through emission and perception of volatile organic compounds (VOCs), it is unclear exactly how these signals are perceived and transmitted. Stirling et al. tease apart the components of within-plant VOC communication using the clever model system of pistil development in […]
