AtCAF-1 mutants show different DNA damage responses after ultraviolet-B than those activated by other genotoxic agents in leaves
(Wiley Blackwell Publishing, Inc, 2019-06)
Chromatin assembly factor-1 (CAF-1) is a histone H3/H4 chaperone that participates in DNA and chromatin interaction processes. In this manuscript, we show that organs from CAF-1 deficient plants respond differently to ...
Identification of genes related to endosperm balance number insensitivity in Paspalum notatum
(Crop Science Society of America, 2017-11)
The endosperm balance number (EBN) theory states that genomic contribution ratio should be kept at 2:1 maternal/paternal (m:p) ratio for normal endosperm development. However, the endosperm formation in apomictic Paspalum ...
Nuclear DNA content in the polyploid complex Turnera ulmifolia (Turnera L., Passifloraceae)
(Springer Wien, 2011-10)
Turnera ulmifolia constitutes a well-studied polyploid complex with allo- and autopolyploid species ranging from 2 to 8x. Flow cytometry was used to determine nuclear DNA content, and to estimate 2C- and 1Cx-values with ...
Sexual modulation in a polyploid grass: a reproductive contest between environmentally inducible sexual and genetically dominant apomictic pathways
(Nature Publishing Group, 2020-05)
In systems alternating between sexual and asexual reproduction, sex increases under unfavorable environmental conditions. In plants producing sexual and asexual (apomictic) seeds, studies on the influence of environmental ...
How to become an apomixis model: The multifaceted case of Paspalum
(MDPI AG, 2020-09)
In the past decades, the grasses of the Paspalum genus have emerged as a versatile model allowing evolutionary, genetic, molecular, and developmental studies on apomixis as well as successful breeding applications. The ...
Chromosome and morphological studies in the mimosa debilis complex (Mimosoideae, Leguminosae) from southern South America
(Csiro Publishing, 2010-04)
Mimosa debilis Humb. Bonpl. ex Willd. and M. nuda Benth. were grouped in specific and infraspecific complexes. Both taxa showed exomorphological similarities, with conflicts in their taxonomic circumscription and present ...
The genetic diversity of wild rescuegrass is associated with precipitation levels
(Springer, 2014-04-27)
The genus Bromus belongs to the family Poaceae, contains over 160 annual and perennial species of grasses, varying in
ploidy level from diploid (2n = 14) to dodecaploid (2n = 70) (Fortune et al. 2008). One of the most ...
Morphological and molecular variability of wild diploid and polyploid populations of Chrysolaena flexuosa (Sims) H. Rob: relevance for ornamental breeding
(Elsevier, 2020-01)
Chrysolaena flexuosa is a South American species of ornamental interest, whose variability has not been explored. The objective of this work was to perform joint analyses of morphological and molecular traits in seven ...
Genetic diversity in a world germplasm collection of tall fescue
(2013)
Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ...
Pollen‐mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense Bitter under experimental field conditions in Argentina
(Wiley, 2013-12)
The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber‐bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ...
