Germplasm Bred for Resistance to Striga hermonthica Exhibited High Resistance Levels to Striga asiatica Compared to Commercial Checks

Advances in Agriculture, Volume 2021, Issue 1, 2021., 2021
Parasitic weeds belonging to the Orobanchaceae family are a menace in Sub‐Saharan African (SSA). Specifically, the two witchweeds from the genus Striga, S. hermonthica and S. asiatica, are jointly responsible for land abandonments and cereal yield reductions in the SSA.

Genome‐Wide Association Studies for Striga asiatica Resistance in Tropical Maize

International Journal of Genomics, Volume 2021, Issue 1, 2021., 2021
Striga asiatica L. is a parasitic weed in cereal crops including maize leading to tremendous yield losses up to 100% under severe infestation. The available S. asiatica control methods include cultural control options such as uprooting and burning the Striga plants before they flower, field sanitation, crop rotation, intercropping, organic matter usage,

RAPD and internal transcribed spacer sequence analyses reveal Zea nicaraguensis as a section Luxuriantes species close to Zea luxurians. [PDF]

PLoS ONE, 2011
Genetic relationship of a newly discovered teosinte from Nicaragua, Zea nicaraguensis with waterlogging tolerance, was determined based on randomly amplified polymorphic DNA (RAPD) markers and the internal transcribed spacer (ITS) sequences of nuclear ...

Enhancing Drought Tolerance and Striga hermonthica Resistance in Maize Using Newly Derived Inbred Lines from the Wild Maize Relative, Zea diploperennis

Agronomy, 2021
Recurrent drought and Striga hermonthica (Del.) Benth parasitism constrains maize production in sub-Saharan Africa (SSA). Transfer of resistance genes from wild relatives can improve resistance to drought and Striga in tropical maize.

Evolutionary relationships in the genus Zea: analysis of repetitive sequences used as cytological FISH and GISH markers

Genetics and Molecular Biology, 2000
The present study is a revision of our work on evolutionary cytogenetics of the genus Zea, including several new experiments which give a deeper insight into the nature of the DNA sequences involved in telomeric regions of Zea luxurians.

Genomic in situ hybridization analysis for identification of introgressed segments in alloplasmic lines from Zea maysxZea diploperennis [PDF]

Hereditas, 2003
In this study, the tested four alloplasmic inbred lines, a2-4, a2-5, b1-1 and b2-1 were propagated from the same disease resistant individual in the parthenogenetic progenies of Zea mays L. cv. Lu 9 x Zea diploperennis (DP). All the lines except a2-5 were resistant to Helminthosporium turcium Pass and H. maydis Nisik.

Cryptic homoeology analysis in species and hybrids of genus Zea

Biologia Plantarum, 2013
Cryptic intergenomic pairing of genus Zea was induced by the use of a diluted colchicine solution in order to elucidate the phylogenetic relations and differentiation of the homoeologous genomes. Results indicate that in species and hybrids with 2n = 20,

Cytogenetic study of a tetraploid hybrid Zea diploperennis * Zea perennis.

CYTOLOGIA, 1985
It had been obtained a tetraploid hybrid (2n=40), crossing Z. diploperennis (2n=20) with Z. perennis (2n=40) by non disjunction of the gametes of Z. diploperennis.The cytological study indicated that there were no univalents and trivalents. Most of the chromosomes paired as bivalents and tetravalents preferently openring.
