Wild teosinte and cultivated maize show differential tolerance to flooding and herbivory stress
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2025-05-01

Morphologic and Transcriptomic Response to Weed Pressure in Multiple Maize (Zea mays L.) Selections and Teosinte (Zea mays L. ssp parviglumis) Lines
… stress). Maize retains ~30% of its ancestral teosinte’s (<em>Zea mays</em> ssp<em> parviglumis</em>) genetic base. Transcriptomic response to weed pressure in maize and teosinte can lead to manipulation of the maize genome to minimize crop yield loss due to weed presence. In maize and teosinte …

Systematic and Cytogenetic Studies of the Genus Zea
Teosinte and maize were divided into four species on the basis of morphology. Zea luxurians, Z. diploperennis, and the tetraploid Z. perennis were grouped under section Luxuriantes, and Z. mays was included in section Zea. Zea mays includes subsp. mays (cultivated maize), subsp. mexicana, and …

Understanding Zea mays genetic influence on the structure and function of the rhizosphere microbiome
… assembly from its ancestral progenitor teosinte, assess whether these genotype driven microbiome assembly processes persist in the field setting and influence N-cycling ecosystem function and finally attempt to determine the underlying genetic regions and mechanisms contributing to …

Comparative analyses identify adaptive genetic variation in crops and crop wild relatives
… inversion in the wild ancestor of maize - teosinte (Zea mays ssp. parviglumis) and characterized its distribution and abundance in natural populations using population genetic approaches. This is also the first study in plants to apply population genetic approaches to identify chromosomal …

Unity, diversity, and resistance: The fight for maíz criollo in southern México
… all sprouting from one common ancestor, teosinte. It is due to this culturally rich and biologically diverse history of corn in México that the GM maize debates of the region are of particular relevance. This thesis aims to serve as a well-rounded presentation of the social resistance …

Natural genetic variation and gene expression patterns underlying lateral shoot (tiller) development in barley (Hordeum vulgare L)
… as some, like UNICULME4 and INTERMEDIUM-C (TEOSINTE BRANCHED 1 ortholog) have already been implicated in tiller development. Genes that were upregulated in ligules compared to leaves were also identified, and clustering of these genes revealed some that were expressed more highly in ligules …

Flavonoid diversification in Hibiscus and its impact on petal pattern evolution
… and non-targeted approaches. Manipulating the TEOSINTE BRANCHED 4 (TCP4) transcription factor affected bullseye size by altering petal growth. Comparative genetics with another H. trionum accession further verified interactions between components of the gene regulatory network and may uncover …

Analysis of Starch Branching Enzyme 1 (SBE1) Gene in Maize
… coding region of 17 accessions of maize and teosinte. Very low proportion of single nucleotide polymorphisms were observed relative to other genes in maize. Comparison of synonymous and nonsynonymous polymorphism revealed the effect of purifying selection in the whole species. Phylogenetic …
