Domestication reshaped the genetic basis of inbreeding depression in a maize landrace compared to its wild relative, teosinte

PLOS GENETICS, 17(12).

Ed(s): B. Walsh

MeSH headings : Domestication; Genes, Plant; Genetic Variation / genetics; Inbreeding Depression / genetics; Phenotype; Plant Breeding; Plant Proteins / genetics; Quantitative Trait Loci / genetics; Selection, Genetic / genetics; Zea mays / genetics; Zea mays / growth & development
TL;DR: This work compared the effects of outcrossing and self-fertilization on 18 traits in a landrace population of maize, which underwent a population bottleneck during domestication, and a neighboring population of its wild relative teosinte, and identified quantitative trait loci representing large-effect rare variants carried by only a single parent, which were more important in teOSinte than maize.

A Genome Wide Association Study Reveals Markers and Genes Associated with Resistance to Fusarium verticillioides Infection of Seedlings in a Maize Diversity Panel

G3-GENES GENOMES GENETICS, 9(2), 571–579.

author keywords: Fusarium verticillioides; resistance to seedling disease; Genome Wide Association Studies; Maize; Rolled Towel Assay; SNPs
MeSH headings : Disease Resistance / genetics; Fusarium / pathogenicity; Genes, Plant; Genome-Wide Association Study; Linkage Disequilibrium; Polymorphism, Single Nucleotide; Seedlings / genetics; Seedlings / microbiology; Zea mays / genetics; Zea mays / microbiology
TL;DR: Functional analysis revealed that many of these genes are directly involved in plant defense against pathogens and stress responses, including transcription factors, chitinase, cytochrome P450, and ubiquitination proteins, and 25 genes were found in high linkage disequilibrium with the associated SNPs identified by GWAS and four of them direct involved in disease resistance.

Genome-wide association analysis for fumonisin content in maize kernels

BMC PLANT BIOLOGY, 19.

author keywords: Maize; Fusarium verticillioides; Fumonisin; Resistance; Genome-wide association study; Candidate gene
MeSH headings : Fumonisins / metabolism; Genome, Plant; Genome-Wide Association Study; Inbreeding; Linear Models; Linkage Disequilibrium / genetics; Polymorphism, Single Nucleotide / genetics; Seeds / metabolism; Zea mays / genetics; Zea mays / metabolism
TL;DR: Breeding approaches to fix favorable functional variants for genes implicated in maize immune response signaling may be especially useful to reduce kernel contamination with fumonisins without significantly interfering in mycelia development and growth and, consequently, in the beneficial endophytic behavior of Fusarium verticillioides.

TL;DR: Overall, genomic selection considering markers distributed throughout the whole genome seems to be a more appropriate breeding strategy than marker-assisted selection focused in markers linked to QTL. (via Semantic Scholar)

Mapping of resistance to corn borers in a MAGIC population of maize

BMC PLANT BIOLOGY, 19(1).

author keywords: Maize; Mediterranean corn borer; Sesamia nonagrioides; Resistance; Mapping with multi-parent advanced generation InterCrosses (MAGIC) populations; Quantitative trait loci (QTL); Genome wide association analysis (GWAS)
MeSH headings : Alleles; Animals; Chromosome Mapping; Disease Resistance / genetics; Genome-Wide Association Study; Genotype; Moths / physiology; Phenotype; Plant Diseases / immunology; Plant Diseases / parasitology; Polymorphism, Single Nucleotide / genetics; Quantitative Trait Loci / genetics; Zea mays / genetics; Zea mays / immunology; Zea mays / parasitology
TL;DR: A mapping population is developed which allowed a finer dissection of the genetics of maize resistance to corn borers and a solid nomination of candidate genes based on functional information and indicates that it is possible the concurrent improvement of resistance and agronomic traits.

MeSH headings : Breeding; Disease Resistance / genetics; Fumonisins; Fusarium / physiology; Plant Diseases / genetics; Plant Diseases / microbiology; Quantitative Trait Loci; Zea mays / genetics; Zea mays / microbiology
TL;DR: The suitability of a maize multiparent advanced-generation intercross population for detecting quantitative trait loci associated with Fusarium ear rot resistance was evaluated and found to be valuable in uncovering genomic regions containing resistance-associated loci in temperate materials.

TL;DR: A strong, nonneutral divergence is identified between teosinte and maize landrace genetic variance–covariance matrices (G-matrices), which indicates that the degree of constraint is more unfavorable for further evolution along the same trajectory. (via Semantic Scholar)

Usefulness of marker-assisted selection to improve maize for increased resistance to Sesamia nonagrioides attack with no detrimental effect on yield

ANNALS OF APPLIED BIOLOGY, 174(2), 219–222.

author keywords: crop science; genetic markers; marker-assisted selection; plant breeding; plant resistance to insects
TL;DR: The suitability of MAS for improving resistance to stem tunnelling without adverse effects on yield has been tested and results encourage us to persevere in using marker information for simultaneous improvement of resistance and yield especially if genome-wide approaches are applied.

Modifications to a LATE MERISTEM IDENTITY1 gene are responsible for the major leaf shapes of Upland cotton (Gossypium hirsutum L.)

Proceedings of the National Academy of Sciences of the United States of America, 114(1), E57–66.

By: R. Andres n, V. Coneva*, M. Frank*, J. Tuttle n, L. Samayoa n, S. Han n, B. Kaur n, L. Zhu n ...

TL;DR: It is shown that the major leaf shapes of cotton at the L-D1 locus are controlled by a HD-Zip transcription factor most similar to Late Meristem Identity1 (LMI1) gene, and that sub-okra is the ancestral leaf shape of tetraploid cotton and normal is a derived mutant allele that came to predominate and define the leafshape of cultivated cotton.

TL;DR: A quantitative trait loci (QTL) mapping study for yield, resistance against MCB attack, and other relevant agronomic traits was performed using a recombinant inbred line (RIL) population derived from the cross A637 × A509 that is expected to segregate forield, and ear, and stalk resistance to MCB.
