The Arabidopsis PAL3 is a carboxy-tyrosine ammonia lyase

Caroline Van Beirs, Ans Van der Vaet, Jan Goeman, Fabricio Almeida‐Silva et autres

Phenylalanine ammonia lyase (PAL) catalyses the deamination of L-phenylalanine, which is the first step of the plant-specific phenylpropanoid pathway. Its position at the intersection of primary and specialized metabolism, combined with its important role in plant growth and adaptive stress response, has …

Metabolic engineering of a tyrosine-specific phenylpropanoid pathway in plants

Caroline Van Beirs, Max Bentelspacher, Congwei Xie, Celien Van de Velde et autres

ABSTRACT While all plants use L-phenylalanine for phenylpropanoid biosynthesis, grasses can also initiate the pathway from L-tyrosine. Curiously, no plant has evolved an exclusive tyrosine-derived route. We generate plants with phenylpropanoid biosynthesis initiated from phenylalanine, tyrosine, or both by expressing a Brachypodium …

The selective estrogen receptor modulator clomiphene inhibits sterol biosynthesis in Arabidopsis thaliana

Qing Wang, Kjell De Vriese, Sandrien Desmet, Ren Wang et autres

Sterols are produced via complex, multistep biosynthetic pathways involving similar enzymatic conversions in plants, animals, and fungi, yielding a variety of sterol metabolites with slightly different chemical properties to exert diverse and specific functions. A tremendously diverse landscape of sterols, and sterol-derived …

Extracellular vesicles of Norway spruce contain precursors and enzymes for lignin formation and salicylic acid

Santeri Kankaanpää, Enni Väisänen, Geert Goeminne, Rabah Soliymani et autres

Lignin is a phenolic polymer in plants that rigidifies the cell walls of water-conducting tracheary elements and support-providing fibers and stone cells. Different mechanisms have been suggested for the transport of lignin precursors to the site of lignification in the cell wall. …

Arbuscular mycorrhizal hyphae facilitate rhizobia dispersal and nodulation in legumes

Jiadong He, Lin Zhang, Judith Van Dingenen, Sandrien Desmet et autres

In soil ecosystems, rhizobia occupy the rhizosphere of legume roots to form nodules, a process triggered by microbial recognition of specific root-derived signals (i.e. flavonoids). However, soil conditions can limit bacterial motility, restricting signal perception to the area directly influenced by roots. …

Strigolactones repress nodule development and senescence in pea

Judith Van Dingenen, Annick De Keyser, Sandrien Desmet, Alexander Clarysse et autres

Strigolactones are a class of phytohormones that are involved in many different plant developmental processes, including the rhizobium-legume nodule symbiosis. Although both positive and negative effects of strigolactones on the number of nodules have been reported, the influence of strigolactones on nodule …

Identification and characterization of CYP71 subclade cytochrome P450 enzymes involved in the biosynthesis of bitterness compounds in Cichorium intybus

Charlotte De Bruyn, Tom Ruttink, Elia Lacchini, Stéphane Rombauts et autres

Industrial chicory (Cichorium intybus var. sativum) and witloof (C. intybus var. foliosum) are crops with an important economic value, mainly cultivated for inulin production and as a leafy vegetable, respectively. Both crops are rich in nutritionally relevant specialized metabolites with beneficial effects …

Opposing effects of trans‐ and cis‐cinnamic acid during rice coleoptile elongation

Lena Vlaminck, Brix De Rouck, Sandrien Desmet, Thijs Van Gerrewey et autres

Abstract The phenylpropanoid cinnamic acid (CA) is a plant metabolite that can occur under a trans‐ or cis‐form. In contrast to the proven bioactivity of the cis‐form (c‐CA), the activity of trans‐CA (t‐CA) is still a matter of debate. We tested both …

Distinct chemical resistance-inducing stimuli result in common transcriptional, metabolic, and nematode community signatures in rice root and rhizosphere

Willem Desmedt, Enoch Narh Kudjordjie, Satish Namdeo Chavan, Sandrien Desmet et autres

Induced resistance (IR), a phenotypic state induced by an exogenous stimulus and characterized by enhanced resistance to future (a)biotic challenge, is an important component of plant immunity. Numerous IR-inducing stimuli have been described in various plant species, but relatively little is known …
