Maize (Zea mays) is a major staple crop in Africa, where its yield and the livelihood of millions are compromised by parasitic witchweed Striga. Germination Striga induced strigolactones exuded from maize roots into rhizosphere. In germplasm collection, we identified two strigolactones, zealactol zealactonoic acid, which stimulate less germination than strigolactone, zealactone. We then showed that single cytochrome P450, ZmCYP706C37, catalyzes series oxidative steps maize-strigolactone...
Parasitic plants are that connect with a haustorium to the vasculature of another, host, plant from which they absorb water, assimilates, and nutrients. Because this parasitic lifestyle, need coordinate their lifecycle host. have evolved number host detection/host response mechanisms germination in chemical signals one major families plants, Orobanchaceae, is striking example. In update review, we discuss these stimulants. We review different compound classes function as stimulants, how...
Sorghum bicolor is among the most important cereals globally and a staple crop for smallholder farmers in sub-Saharan Africa. Approximately 20% of sorghum yield lost annually Africa due to infestation with root parasitic weed Striga hermonthica. Existing management strategies are not singularly effective integrated approaches needed. Here, we demonstrate functional potential soil microbiome suppress infection sorghum. We associate this suppression microbiome-mediated induction endodermal...
Plants deposit photosynthetically-fixed carbon in the rhizosphere, thin soil layer directly around root, thereby creating a hospitable environment for microbes. To manage inhabitants of this nutrient-rich environment, plant roots exude and dynamically adjust microbe-attracting -repelling compounds to stimulate specific members microbiome. Previously, we demonstrated that foliar infection Arabidopsis thaliana by biotrophic downy mildew pathogen Hyaloperonospora arabidopsidis (Hpa) leads...
Abstract The development of potent strigolactone (SL) agonists as suicidal germination inducers could be a useful strategy for controlling root parasitic weeds, but uncertainty about the SL perception mechanism impedes real progress. Here we describe small-molecule that efficiently stimulate Phelipanchce aegyptiaca , and Striga hermonthica in concentrations low 10 −8 to −17 M. We show full efficiency synthetic triggering signaling through receptor, ShHTL7, depends on receptor-catalyzed...
Sorghum bicolor is among the most important cereals in world and a staple crop sub‑Saharan Africa. Approximately 20% of sorghum yield annually lost Africa to infestation with root parasitic weed Striga hermonthica. Existing management strategies show low efficacy. Novel, integrated approaches are needed as an alternative strategy. Here, we demonstrate that soil microbiome suppresses infection sorghum. We associate this suppression microbiome-mediated induction endodermal suberization...
Flax for oil seed is a crop of increasing popularity, but its cultivation needs technical improvement. Important agronomic traits such as productivity and resistance to stresses are be regarded the result combined responses individual organs their inter-communication. Ultimately, these directly reflect metabolic profile at cellular level. Above ground, complexity plant phenotype governed by leaves different developmental stages, ability synthesise exchange metabolites. In this study,...
Abstract Two sorghum varieties, Shanqui Red (SQR) and SRN39, have distinct levels of susceptibility to the parasitic weed Striga hermonthica, which been attributed different strigolactone composition within their root exudates. Root exudates Striga-susceptible variety contain primarily 5-deoxystrigol, has a high efficiency for inducing germination. SRN39 roots exude orobanchol, leading reduced germination making this resistant Striga. The structural diversity in exuded strigolactones is...
Abstract Sorghum bicolor is one of the most important cereals in world and a staple crop for smallholder famers sub-Saharan Africa. However approximately 20% sorghum yield annually lost on African continent due to infestation with root parasitic weed Striga hermonthica. Existing management strategies often show an inconsistent low efficacy. Hence, novel integrated approaches are needed as alternative strategy. Here, we demonstrate that soil microbiome suppresses infection sorghum. We...
Cell wall localized heterogeneous polyesters are widespread in land plants. The composition of these polyesters, such as cutin, suberin, or more plant-specific forms the flax seed coat lignan macromolecule, can be determined after total hydrolysis ester linkages. main bottleneck structural characterization macromolecules, however, resides determination higher order monomer sequences. Partial hydrolysates release a complex mixture fragments different lengths, each present low abundance and...
Potato Cyst Nematodes (PCNs) are an economically important pest for potato growers. A crucial event in the life cycle of nematode is hatching, after which juvenile will move toward host root and infect it. The hatching PCNs induced by known unknown compounds exudates plant species, called factors (HFs, induce independently), such as solanoeclepin (solA), or stimulants (HSs, enhance activity HFs). Unraveling identity HSs HFs their natural variation selection cultivars that produce low amounts...
The root parasitic weed
In recent years, Camelina sativa (L.) Crantz has known a renewed interest for its agronomic potential. This oilseed crop short development cycle (85 – 100 days) and is naturally tolerant to biotic abiotic stresses [1]. Brassicaceae undemanding in fertilizer input requires less pesticide compared traditional crops [2]. Currently this plant mainly grown seeds with unusual fatty acid profile [3] phytochemical investigations of the are still emerging. order complete characterization Camelina,...
Abstract Variation in strigolactone composition sorghum root exudates underlies its resistance to the parasitic weed, Striga hermonthica . Root of susceptible variety Shanqui Red (SQR) contain primarily 5-deoxystrigol, which has a high efficiency inducing germination. SRN39 roots exude orobanchol, leading reduced germination and making this resistant Striga. This structural diversity exuded strigolactones is determined by polymorphism LGS1 ( LOW GERMINATION STIMULANT 1 ) locus. Yet, effects...
