Beyond arabidopsis: differential UV-B response mediated by UVR8 in diverse species
(Frontiers Media, 2019-06)Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that regulates growth and development in plants. Two dose-dependent UV-B response pathways were described in plants: a specific one, mediated ... -
Mate choice confers direct benefits to females of Anastrepha fraterculus (Diptera: Tephritidae)
(Public Library of Science, 2019-06)Exposure to plant compounds and analogues of juvenile hormone (JH) increase male mating success in several species of tephritid fruit flies. Most of these species exhibit a lek mating system, characterized by active female ... -
Taking advantage og organelle genomes in plant breeding: an integrated approach = Aprovechando los genomas de las organelas en el mejoramiento genético de plantas: un enfoque integrado
(Sociedad Argentina de Genética, 2019-07)Plant cells carry their genetic information in three compartments: the nucleus, the plastids and the mitochondria. In last years, next-generation sequencing has allowed the development of genomic databases, which are ... -
The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings
(Nature Publishing Group, 2019-07)Previously, through a TILLING (Targeting Induced Local Lesions in Genomes) approach applied on barley chloroplast mutator (cpm) seedlings a high frequency of polymorphisms in the rpl23 gene was detected. All the polymorphisms ... -
Generalized glycogenosis in Brahman-derived breeds: diagnosis and prevalence in Argentina
(Springer, 2019-08)Generalized glycogenosis is a lethal autosomal recessive disease caused by a deficient activity of the acidic 1,4-α-glucosidase enzyme and characterized by an accumulation of glycogen within lysosomes. Three mutations in ... -
Shortening of generation cycles in inbred lines of maize (Zea mays L.) through embryo rescue technique
(Istituto Sperimentale per la Cerealicoltura, 2019-11)Embryo rescue techniques have been used as an approach to raise hybrids from incompatible crosses. These techniques have also proved to be valuable tools for maize improvement, since they allow reducing the duration of the ... -
PCR identification of petunia male sterile cytoplasm = Identificação por PCR de citoplasma macho estéril em Petunia
(Sociedade Brasileira de Floricultura e Plantas Ornamentais, 2019-12)Petunia is a very important ornamental plant with a broad range of flower colour and size, and most of the cultivars grown are propagated through seeds. Cytoplasmic male sterility (CMS) is a maternally inherited character ... -
The “polyploid effect” in the breeding of aromatic and medicinal species
(Elsevier, 2020-01)The secondary metabolism of plants delivers a wide range of chemical structures with application for a vast array of activities, thus offering opportunities for social and economic development. Polyploidy is the possession ... -
Genetic variation and heteroplasmy of Varroa destructor inferred from ND4 mtDNA sequences
(Springer, 2020-02)Varroa destructor, a parasitic mite of the western honey bee, Apis mellifera L., is a serious threat to colonies and beekeeping worldwide. Population genetics studies of the mite have provided information on two mitochondrial ... -
pBAR–H3.2, a native-optimized binary vector to bypass transgene silencing in alfalfa
(Springer, 2020-03)Alfalfa is the main forage worldwide due to its high biomass production, excellent nutritional qualities and adaptation to a wide range of environments (Singer et al. 2018). Besides, due to its ability to grow without ... -
Argentina’s local crop biotechnology developments: why have they not reached the market yet?
(Frontiers Media, 2020-04)Plant biotechnology in Argentina started at the end of the 1980s, leading to the development of numerous research groups in public institutions and, a decade later, to some local private initiatives. The numerous scientific ... -
Wolbachia pipientis associated with tephritid fruit fly pests: from basic research to applications
(Frontiers Media, 2020-06)Members of the true fruit flies (family Tephritidae) are among the most serious agricultural pests worldwide, whose control and management demands large and costly international efforts. The need for cost-effective and ... -
High - efficiency direst somatic embryogenesis and plant regeneration from leaf base plants of "peperina" (Minthostachys verticillata)
(Springer, 2020-07-30)In vitro culture has been recognized as a potential plant clonal propagation tool for a broad variety of commercial, ornamental, and medicinal species, with applications in both industrial and academic laboratories. In ... -
Infestation of fruit by conspecific and heterospecific females deters oviposition in two Tephritidae fruit fly species
(Wiley, 2020-09)Tephritidae fruit fly larvae develop entirely in the host chosen by the females. To improve the fitness of their progeny, females would benefit from rejecting previously exploited hosts. Anastrepha fraterculus and Ceratitis ... -
Synthetic multi-antibiotic resistant plasmids in plant-associated bacteria from agricultural soils
(Elsevier, 2020-09)Objectives: Unlike higher organisms such as domestic animals and cultivated plants, which display a robust reproductive isolation and limited dispersal ability, microbes exhibit an extremely promiscuous gene flow and can ... -
