Crystalline ZIF-8 (C-ZIF-8) and amorphous ZIF-8 (Am-ZIF-8) were prepared and investigated to control the germination of Strigahermonthica, a root parasitic plant, which threatens cereal cropsproduction particularly in sub-Saharan Africa. We have demonstratedthat Am-ZIF-8 shows a better performance than C-ZIF-8 in inhibitingStriga seeds germination. This efficient performance of Am-ZIF-8materials can be attributed to the incomplete deprotonation […]

Emeline N. Dossa*, Hussein Shimelis, Admire I. T. Shayanowako In this study, genetically diverse and complementary lines were selected among tropical and sub-tropical maize populations that will facilitate the breeding of maize varieties with Striga resistance and market-preferred traits. Fig 3. Sub-population inference among the 126 maize genotypes based on 16000 SNPs: (A) likelihood and […]

The yield of pearl millet, a resilient cereal crop crucial for African food security, is severely impacted by the root parasitic weed Striga hermonthica, which requires host-released hormones, called strigolactones (SLs), for seed germination. Herein, we identify four SLs present in the Striga-susceptible line SOSAT-C88-P10 (P10) but absent in the resistant 29Aw (Aw). We generate […]

Strigolactones exhibit dual functionality as regulators of plant architecture and signaling molecules in the rhizosphere. The important model crop rice exudes a blend of different strigolactones from its roots. Here, we identify the inaugural noncanonical strigolactone, 4-oxo-methylcarlactonoate (4-oxo-MeCLA), in rice root exudate. Comprehensive, cross-species coexpression analysis allowed us to identify a cytochrome P450, OsCYP706C2, and two methyl transferases as […]

Summary The parasitic plant genus Striga causes major yield losses to several crops such as sorghum, millet, and rice in arid and semi-arid regions of the tropics. For Striga to successfully parasitize its host plant, two conditions should be fulfilled: suitable germination conditions and the presence of a host plant that exudes so-called germination stimulants, strigolactones, that are also […]
