Gordon Research Conference on Carotenoids
The rice orobanchol synthase catalyzes the hydroxylation of the noncanonical strigolactone methyl 4-oxo-carlactonoate.
I am pleased to share our latest publication on strigolactone (SL) biosynthesis in rice: DOI: 10.1111/nph.20135 […]
Genome-wide association analysis of grain yield and Striga hermonthica and S. asiatica resistance in tropical and sub-tropical maize populations
Emeline N. Dossa, Hussein Shimelis, and Admire I. T Shayanowako School of Agricultural, Earth and Environmental Sciences, University of KwaZulu-Natal, Private Bag X01, Scottsville, Pietermaritzburg 3209, South Africa This study reports novel QTL and related genes for Striga asiatica and S. hermonthica resistance in maize. No QTL associated with dual resistance was found, suggesting that […]
Inhibition of the Germination of Root Parasitic Plants by Zeolitic Imidazolate Framework-8
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 […]
Genetic diversity analysis of tropical and subtropical maize germplasm for Striga resistance and agronomic traits with SNP markers
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 […]

Chromosome-scale pearl millet genomes reveal CLAMT1b as key determinant of strigolactone pattern and Striga susceptibility
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 […]

OsCYP706C2 diverts rice strigolactone biosynthesis to a noncanonical pathway branch
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 […]
