Stem-cell-triggered immunity safeguards cytokinin enriched plant shoot apexes from pathogen infection
Intricate mechanisms discriminate between friends and foes in plants. Plant organs deploy overlapping and distinct protection strategies. Despite vulnerability to a plethora of pathogens, the growing tips of plants grow bacteria free. The shoot apical meristem (SAM) is among three stem cells niches, a self-renewable reservoir for the future organogenesis of leaf, stem, and flowers. How plants s...

متن کاملStem-cell-triggered immunity through CLV3p–FLS2 signalling
Stem cells in the shoot apical meristem (SAM) of plants are the selfrenewable reservoir for leaf, stem and flower organogenesis. In nature, disease-free plants can be regenerated from SAM despite infections elsewhere, which underlies a horticultural practice for decades. However, the molecular basis of the SAM immunity remains unclear. Here we show that the CLAVATA3 peptide (CLV3p), expressed a...
متن کاملMultiple feedback loops through cytokinin signaling control stem cell number within the Arabidopsis shoot meristem.
A central unanswered question in stem cell biology, both in plants and in animals, is how the spatial organization of stem cell niches are maintained as cells move through them. We address this question for the shoot apical meristem (SAM) which harbors pluripotent stem cells responsible for growth of above-ground tissues in flowering plants. We find that localized perception of the plant hormon...
متن کاملThe Role of Auxin-Cytokinin Antagonism in Plant-Pathogen Interactions
It has been several decades since Skoog and Miller described the contrasting behavior of auxin and cytokinin in promoting the growth of root and shoot, respectively [1]. In recent years, a lot of progress has been made in understanding the regulation of stem cell niche and cell fate in both shoot and root apical meristems. Developmental processes such as the maintenance of root meristems [2], l...
