Plants perceive and respond to volatile signals in their environment. Herbivore-infested plants release organic compounds (VOCs) which can initiate systemic defense reactions within the plant contribute plant-plant communication. Here, for Ipomoea batatas (sweet potato) leaves we show that among various herbivory-induced volatiles, (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT) had highest abundance of all emitted compounds. This homoterpene was found being sufficient a volatile-mediated induction...
Auxin (indole-3-acetic acid, IAA) is an important phytohormone involved in root growth and development. Root-interacting beneficial pathogenic fungi utilize auxin its target genes to manipulate the performance of their hosts for own needs. In order follow visualize effects fungi-colonized Arabidopsis roots, we used dual reporter construct DR5::EGFP-DR5v2::tdTomato fluorescence microscopy as well LC-MS-based analyses. We demonstrate that endophytic Piriformospora indica Mortierella hyalina...
Summary Cellular calcium (Ca) transients are endogenous signals involved in local and systemic signaling defense activation upon environmental stress, including wounding herbivory. Still, not all Ca 2+ channels contributing to the have been identified, nor their modes of action fully known. Plant annexins proteins capable binding anionic phospholipids can exhibit channel‐like activity. Arabidopsis ANNEXIN1 (ANN1) is suggested contribute transport. Here, we report that...
Abstract Sweet potato ( Ipomoea batatas ) is an important tuber crop, but also target of numerous insect pests. Intriguingly, the abundant storage protein in tubers, sporamin, has intrinsic trypsin protease inhibitory activity. In leaves, sporamin induced by wounding or a volatile homoterpene and enhances resistance. While signalling pathway leading to synthesis partially established, initial event, perception stress‐related signal still unknown. Here, we identified Ib LRR‐RK1 that upon...
Abstract The degradation of chlorophyll, the omnipresent green pigment, has been investigated intensively over last 30 years resulting in many elucidated tetrapyrrolic products. With a comparison to structurally similar heme, we hereby propose novel additional chlorophyll mechanism mono‐ and dipyrrolic This is first proof occurrence family dipyrrols leaves that are previously only known as heme product also found spit feces herbivores with specific metabolomic patterns reflecting origin...
Microbial volatiles are important factors in symbiotic interactions with plants. Mortierella hyalina is a beneficial root-colonizing fungus garlic-like smell, and promotes growth of Arabidopsis seedlings. GC-MS analysis the M. headspace NMR extracted essential oil identified sulfur-containing volatile tris(methylthio)methane (TMTM) as major compound. Incorporation sulfur from fungal into plant metabolism was shown by 34S labeling experiments. Under deficiency, TMTM down-regulated...
