Does abscisic acid affect strigolactone biosynthesis? [PDF]

open access: yes, 2010
Strigolactones are considered a novel class of plant hormones that, in addition to their endogenous signalling function, are exuded into the rhizosphere acting as a signal to stimulate hyphal branching of arbuscular mycorrhizal (AM) fungi and germination

Screening Sorghum for Resistance to Striga Hermonthica (Del.) Benth

open access: yesNova Journal of Medical and Biological Sciences, 2014
The root hemiparasitic weed Striga hermonthica is a serious constraint to grain production of economically important cereals in sub-Saharan Africa. Six cultivars of sorghum Abu sabien, were tested for resistance and tolerance to this root hemi-parasite by applying one of two levels of Striga infestation (2 and 4 mg/pot).

Presowing hardening of the host with phenolic acids reduces induction of seed germination in the root parasite Striga asiatica [PDF]

open access: yes, 1980
S. asiatica, A root parasite, causes severe loss of yield in sorghum and several other crops. The seeds of the parasite are induced to germinate by a stimulant in the host root exudate. Presowing hardening of the host with vanillic acid [121-​34-​6]​,

Increasing the diversity of Sycorax Haliday, 1839 (Diptera: Psychodidae) in the Neotropical region: New species from the Brazilian Atlantic Forest

open access: yesAustral Entomology, Volume 65, Issue 1, February 2026.
Abstract Four new species of Sycorax Haliday, 1839 are described: Sycorax alumna sp. nov., Sycorax catarina sp. nov., Sycorax paranaensis sp. nov., and Sycorax striga sp. nov., with the females of Sycorax striga sp. nov. bearing characteristics that suggest haematophagous behaviour.

Strigolactone biosynthesis lgs1 mutant alleles mined from the sorghum accession panel are a promising resource of resistance to witchweed (Striga) parasitism

open access: yesPlants, People, Planet
Societal Impact Statement Striga is a parasitic plant that greatly limits the production of Africa's most staple cereals, including sorghum. Infection occurs when the parasite germinates in response to biomolecules emitted into the soil from the host's ...

Assessment of Striga gesnerioides (Willd.) Resistance and Genetic Characterization of Forty-Six Cowpea (Vigna unguiculata (L.) Walp.) Genotypes in Ghana

open access: yesInternational Journal of Agronomy, 2020
The parasitic weed, Striga gesnerioides, imposes physiological stress on cowpea (Vigna unguiculata (L.) Walp.) resulting in significant yield loss in the regions of northern Ghana.

Genetic interrelationships of elite sorghum (Sorghum bicolor (L.) Moench) genotypes bred for Striga resistance and compatibility with Fusarium oxysporum f. sp. strigae (FOS) revealed by microsatellites

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2021
Genetic diversity is key for breeding population development, hybrid breeding, heterotic grouping and genetic analysis, among others. The objective of this study was to examine genetic interrelationships among elite sorghum genotypes bred for resistance ...

Development of Extra-Early Provitamin A Quality Protein Maize Inbreds with Resistance/Tolerance to Striga hermonthica and Soil Nitrogen Stress

open access: yesAgronomy, 2021
A hemiparasitic plant, Striga hermonthica (Del.) Benth and soil nitrogen stress are the key constraints to maize (Zea mays L.) productivity in sub-Saharan Africa, where commonly cultivated maize is the normal endosperm type that is deficient in ...

Do NERICA rice cultivars express resistance to Striga hermonthica (Del.) Benth. and Striga asiatica (L.) Kuntze under field conditions? [PDF]

open access: yesField Crops Research, 2015
Les mauvaises herbes parasites Striga asiatica et Striga hermonthica provoquent des pertes de rendement élevées dans le riz des hautes terres pluviales en Afrique. Deux classes de résistance (pré et post-attachement) et plusieurs génotypes résistants ont été identifiés précédemment parmi les cultivars NERICA (New Rice for Africa) en conditions de ...
