Gene expression and sensitivity in response to copper stress in rice leaves*
TLDR
The results indicate that defence-related genes involved in phytoalexin and lignin biosynthesis were the most sensitive to Cu, and that plant management of abiotic and pathogen stresses has overlapping components, possibly including signal transduction.
Protonema of the moss Funaria hygrometrica can function as a lead (Pb) adsorbent
TLDR
Energy-dispersive X-ray spectroscopy revealed that Pb is localized to the cell walls, endoplasmic reticulum-like membrane structures, and chloroplast thylakoids, suggesting that multiple Pb retention mechanisms are operating in living F. hygrometrica.
Copper mediates auxin signalling to control cell differentiation in the copper moss Scopelophila cataractae
TLDR
The early stage of protonemal development in S. cataractae is shown to be controlled by Cu through auxin signalling, which indicates that copper moss is restricted to Cu-enriched environments.
The Histone Deacetylase Inhibitor Suberoylanilide Hydroxamic Acid Alleviates Salinity Stress in Cassava
TLDR
The results suggest that epigenetic manipulation might enhance tolerance to high salinity stress in cassava, and the HDAC inhibitor, suberoylanilide hydroxamic acid (SAHA), is used for this purpose.
Differential Metal Tolerance and Accumulation Patterns of Cd, Cu, Pb and Zn in the Liverwort Marchantia polymorpha L.
TLDR
A positive correlation between tissue concentration, metal translocation and an enhanced toxic response is observed and the model liverwort Marchantia polymorpha might contribute not only in the application of this species in environmental studies with heavy metals but also as a starting point to study the evolution of metal tolerance in land plants.
Evolution of apolar sporocytes in marchantialean liverworts: implications from molecular phylogeny
TLDR
The phylogenetic analyses indicate that the simplified sporophytes of several marchantialean liverworts are not a primitive condition but rather represent the result of reductive evolution and the loss of the quadripolarity of sporocytes appears to correlate with the evolutionary trend of the sporophyte towards reductions.
Strigolactones regulate arsenate uptake, vacuolar-sequestration and antioxidant defense responses to resist arsenic toxicity in rice roots.
TLDR
Results highlight that strigolactones are involved in arsenic-stress mitigation by regulating arsenate-uptake, glutathione-biosynthesis, vacuolar-sequestration of arsenic and antioxidant defense responses in rice roots.
Funaria hygrometrica Hedw. elevated tolerance to D2O: its use for the production of highly deuterated metabolites
TLDR
The ability to tolerate high concentrations of D2O together with the development of a rich molecular toolbox makes F. hygrometrica an ideal system for the production of valuable deuterated metabolites.
Chemistry of fly ash and cyclone ash leachate from waste materials and effects of ash leachates on bacterial growth, nitrogen-transformation activity, and metal accumulation.
TLDR
The results suggest that cyclone ash can be further studied for reuse, perhaps as a soil amendment, and Pb was found to be highly accumulated in B. subtilis cells, and should be carefully monitored when waste ash is reused in the environment.
