Increase in Multivalent Frequency in F1, Hybrids of Zea Diploperennis × Z. Perennis by Colchicine Treatment

open access: yesHereditas, 2004
Studies of meiotic configurations of colchicine treated and untreated Zea diploperennis ( AdAd BdBd) and two F, synthetic Z. diploperennis x Z. perennis hybrids (2n = 30, ApAp’Ad BplBpZBd and 2n = 40, ApAp’AdAd Bpl Bp2BdBd) were made. Pre-zygotene colchicine treatment produces an increase in the frequency of multivalents (trivalents and quadrivalents ...

Phylogenomic study of selected species within the genus Zea : mutation rate analysis of complete chloroplast genomes [PDF]

open access: yes, 2015
This project examines the relationships within the genus Zea using complete chloroplast genomes (plastomes). Zea mays is one of the most widely cultivated crop species in the world. Billions of dollars have been spent in the commercial agriculture sector

Cytological diploidization of paleopolyploid genus Zea: Divergence between homoeologous chromosomes or activity of pairing regulator genes? [PDF]

open access: yes, 2018
Cytological diploidization process is different in autopolyploid and allopolyploid species. Colchicine applied at the onset of meiosis suppresses the effect of pairing regulator genes resulting multivalents formation in bivalent-forming species ...

Inducción de infección en Teosinte (Zea diploperennis) con el fitopatógeno Ustilago maydis.

open access: yesJOURNAL OF NEGATIVE AND NO POSITIVE RESULTS, 2017
Introduction: The corn and teosinte share morphological and molecular similarities latter being those that support the theory of teosinte (Zea parviglumis) as its predecessor, both species are attacked by specific pathogens like Ustilago maydis. Objective: To analyze the infectious process that presents U.

Analysis of the Pseudoalteromonas tunicata genome reveals properties of a surface-associated life style in the marine environment [PDF]

open access: yes, 2008
Background: Colonisation of sessile eukaryotic host surfaces (e.g. invertebrates and seaweeds) by bacteria is common in the marine environment and is expected to create significant inter-species competition and other interactions.
