Oxidative stress measurement in different morphological forms of wild-type and mutant cyanobacterial strains: Overcoming the limitation of fluorescence microscope-based method.

Ecotoxicol Environ Saf 2020 May 25;200:110730. Epub 2020 May 25.

Centre of Advanced Study in Botany, Department of Botany, Institute of Science, Banaras Hindu University, Varanasi, 221005, India. Electronic address:

Monitoring of oxidative stress caused by a wide range of reactive oxygen species (ROS) is essential to have an idea about the fitness and growth of photosynthetic organisms. The imaging-based oxidative stress measurement in cyanobacteria using 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) dye has the limitation of small sample size as the only selected number of cells are analyzed to measure the ROS levels. Here, we developed a method for oxidative stress measurement by DCFH-DA and flow cytometer (FCM) using unicellular Synechococcus elongatus PCC 7942 and filamentous Fremyella diplosiphon BK14 cyanobacteria.

Diversity of parental environments increases phenotypic variation in Arabidopsis populations more than genetic diversity but similarly affects productivity.

Ann Bot 2020 May 28. Epub 2020 May 28.

CIDE-CSIC, C. Naquera Km 4.5, Montcada, Valencia, Spain.

Background And Aims: The observed positive diversity effect on ecosystem functioning has been scarcely assessed in terms of intraspecific trait variability within populations. Intraspecific phenotypic variability could stem both from underlying genetic diversity and plasticity in response to environmental cues. The latter might derive from modifications on plant's epigenome and potentially last multiple generations in response to previous environmental conditions. Read More

Inter- and intraspecific variation in grass phytolith shape and size: a geometric morphometrics perspective.

Ann Bot 2020 May 28. Epub 2020 May 28.

Center for Theoretical Study, Joint Research Institute of Charles University and Czech Academy of Sciences, Husova, Praha, Czech Republic.

Background And Aims: The relative contributions of inter- and intraspecific variation in phytolith shape and size have only been investigated in a limited number of studies. However, a detailed understanding of phytolith variation patterns among populations or even within a single plant specimen is of key importance for the correct taxonomic identification of grass taxa in fossil samples and for the reconstruction of vegetation and environmental conditions in the past. In this study, we used geometric morphometric analysis for the quantification of different sources of phytolith shape and size variation. Read More

Urbanization and Carpobrotus edulis invasion alter the diversity and composition of soil bacterial communities in coastal areas.

FEMS Microbiol Ecol 2020 May 28. Epub 2020 May 28.

Centre for Invasion Biology, Department of Botany and Zoology, Stellenbosch University, Matieland, South Africa.

Coastal dunes are ecosystems of high conservation value that are strongly impacted by human disturbances and biological invasions in many parts of the world. Here we assessed how urbanization and Carpobrotus edulis invasion affect soil bacterial communities on the north-western coast of Spain, by comparing the diversity, structure and composition of soil bacterial communities in invaded and uninvaded soils from urban and natural coastal dune areas. Our results suggest that coastal dune bacterial communities contain large numbers of rare taxa, mainly belonging to the phyla Actinobacteria and Proteobacteria. Read More

Amphicarpic plants: definition, ecology, geographic distribution, systematics, life history, evolution and use in agriculture.

Biol Rev Camb Philos Soc 2020 May 28. Epub 2020 May 28.

State Key Laboratory of Vegetation and Environmental Change, Institute of Botany, Chinese Academy of Sciences, Beijing, 100093, P.R. China.

Although most plants produce all of their fruits (seeds) aboveground, amphicarpic species produce fruits (seeds) both above- and belowground. Our primary aims were to determine the number of reported amphicarpic species and their taxonomic, geographic, life form and phylogenetic distribution, to evaluate differences in the life history of plants derived from aerial and subterranean seeds, to discuss the ecological and evolutionary significance of amphicarpy, to explore the use of amphicarpic plants in agriculture, and to suggest future research directions for studies on amphicarpy. Amphicarpy occurs in at least 67 herbaceous species (31 in Fabaceae) in 39 genera and 13 families of angiosperms distributed in various geographical regions of the world and in various habitats.

Patterns of variation in distylous traits and reproductive consequences in Erythroxylum species and populations.

Am J Bot 2020 May 28. Epub 2020 May 28.

Biotechnology Institute, Federal University of Catalão, Catalão, Goiás, Brazil.

Premise: Distylous species possess two floral morphs with reciprocal positioning of stigmas and anthers that is hypothesized to promote disassortative pollination. Theoretical models predict equal morph frequencies, but many populations depart from the expected 1:1 ratio, a pattern that often correlates with asymmetric mating between morphs and/or presence of a weak incompatibility system. Variation in reciprocity can also affect the likelihood of disassortative pollination and, hence, reproductive fitness. Read More

Response of young Nerium oleander plants to long-term non-ionizing radiation.

Planta 2020 May 27;251(6):108. Epub 2020 May 27.

Section of Botany, Faculty of Biology, National and Kapodistrian University of Athens, 15701, Ilissia, Athens, Hellas, Greece.

Main Conclusion: Although exposure to low frequency electromagnetic radiation is harmful to plants, LF-EM irradiated Nerium oleander seedlings exhibited enhanced development and growth, probably taking advantage of defined structural leaf deformations. Currently, evidence supports the undesirable, often destructive impact of low frequency electromagnetic (LF-EM) radiation on plants. The response of plants to LF-EM radiation often entails induction in the biosynthesis of secondary metabolites, a subject matter that is well documented. Read More
