Adaptation Dynamic and Evolutionary rescue under sulphide selection in cyanobacteria
(2019-04-26)Los baños de La Hedionda (Cásares, Málaga, España) derivan de un manantial de aguas sulfurosas con una concentración media en torno a 0.2 mM de H2S. Esta concentración es suficiente para inhibir el crecimiento de microorganismos ... -
An evolutionary approach to detect the maximum potential adaptation of Microscystis aeruginosa to salinity
Melero-Jiménez, Ignacio José; Martín-Clemente, Elena; García-Sánchez, María Jesús
; Flores-Moya, Antonio; Bañares-España, Elena (2017-09-13)
Backgrounds Salinity is increasing in many inland waters, on a world-wide scale, due to agricultural practices, droughts, or rise in sea level. In order to understand the effects of increased salinity on freshwater ... -
Characterization of the cyanobacterium Oscillatoria sp. isolated from extreme sulphureous water from Los Baños de la Hedionda (S Spain)
Martín-Clemente, Elena; Melero-Jiménez, Ignacio José; Reul, Andreas; Hernández-López, Miguel; Salvo-Tierra, Ángel Enrique; Bañares-España, Elena; García-Sánchez, María Jesús; Flores-Moya, Antonio[et al.] (2017-09-15)
Los Baños de la Hedionda (Málaga, S Spain) is a natural sulphureous spa (150-200 µM sulphide). Although this high sulphide levels can affect the photosynthetic process, there are numerous photosynthetic microorganisms ... -
Disentangling mechanisms involved in the adaptation of the cyanobacterium Microcystis aeruginosa to the extreme sulphureous water from Los Baños de la Hedionda (S Spain)
Martín-Clemente, Elena; Melero-Jiménez, Ignacio José; Reul, Andreas; Hernández-López, Miguel; Salvo-Tierra, Ángel Enrique; Bañares-España, Elena; García-Sánchez, María Jesús; Flores-Moya, Antonio[et al.] (2017-09-15)
Backgrounds Los Baños de la Hedionda (Málaga, S Spain) is a natural sulphureous spa where sulphide can reach a concentration of 150-200 µM. Although this ion has biocide properties, including inhibition of the photosynthetic ... -
Environmental change rate and dispersion pattern modulate the dynamics of evolutionary rescue of the cyanobacterium Microcystis aeruginosa
Melero-Jiménez, Ignacio José; Martín-Clemente, Elena; Reul, Andreas; Bañares-España, Elena; García-Sánchez, María Jesús; Flores-Moya, Antonio[et al.] (2018-11-21)
The rate of biodiversity loss is so high that some scientists affirm that we are being witnesses of the sixth mass extinction. In this situation, it is necessary to ask the following question: can the organisms be able to ... -
The limit of sulphide adaptation in the sulphide-sensitive cyanobacterium "Microcystis aeruginosa"
Martín-Clemente, Elena; Melero-Jiménez, Ignacio José; Bañares-España, Elena; Flores-Moya, Antonio; García-Sánchez, María Jesús (Universidad de Málaga/Sociedad Española de Microbiología, 2019)
Although sulphide has played an important role in the evolution of photosynthesis, it produces a lethal effect on most photosynthetic organisms due to its redox activity on certain enzymes, inhibiting oxygenic photosynthetic ... -
The limit of the genetic adaptation to herbicides in freshwater phytoplankton and the adaptation photosynthetic cost
Melero-Jiménez, Ignacio José; Martín-Clemente, Elena; Bañares-España, Elena; Reul, Andreas; García-Sánchez, María Jesús; Flores-Moya, Antonio[et al.] (2019-07-31)
Background: One of the most important anthropogenic impacts on freshwater aquatic ecosystems is the continuous increase of herbicide concentrations, which impacts on the structure of phytoplankton communities. Objectives: ... -
Photosynthetic performance in cyanobacteria with increased sulphide tolerance: an analysis comparing wild-type and experimentally derived strains
Martín-Clemente, Elena; Melero-Jiménez, Ignacio José; Bañares-España, Elena; Flores-Moya, Antonio; García-Sánchez, María Jesús (Springer, 2021-11-22)
Sulphide is proposed to have influenced the evolution of primary stages of oxygenic photosynthesis in cyanobacteria. However, sulphide is toxic to most of the species of this phylum, except for some sulphide-tolerant species ... -
Temporal variability of Oscillatoria sp. in extreme environment: a sulfide-rich spring outflow
Reul, Andreas; Martín-Clemente, Elena; Melero-Jiménez, Ignacio José; Hernández-López, Miguel; Toro-Gil, Francisco Javier; Bañares-España, Elena; Flores-Moya, Antonio; García-Sánchez, María Jesús[et al.] (2017-09-13)
Backgrounds The Hedionda Spa (Andalucía, southern Spain) is a sulfide-rich spring outflow, but despite the inhibitory effect of sulfide on photosynthesis, a phytoplankton community inhabits this extreme environment. Objectives ... -
Variation of seed characteristic from natural and artificial selection in the genus Papaver
(2015-06-29)Papaveraceae is a mediterranean plant family with an important scientific, commercial and ethnobotanical interest. Includes wild species, which are distributed throughout the Spanish territory, as Papaver rhoeas, P. dubium, ...
