The possible role of photorespiration as a general stress protection mechanism, and in C(4) plant metabolism, is controversial. In particular, the potential involvement of photorespiration in the acquisition of desiccation tolerance in 'resurrection' plants is unknown. An investigation was carried out into whether photorespiration is present in leaves of the C(4) resurrection plant Sporobolus s...

Photosynthetic processes in Zostera japonica, an upper intertidal species, were found to be more severely affected by desiccation than Z. marina, a lower intertidal and subtidal species, at comparable levels of tissue water content. The data indicate that photosynthetic responses to desiccation at the level of the individual leaf are insufficient to explain observed patterns of intertidal seagr...

Rehydration of Tortula ruralis in 2,4-dinitrophenol inhibits protein synthesis, polysome formation, and ATP production. Polysomes are conserved intact and are active in vitro in hydrated Tortula placed in this chemical, although in vivo protein synthesis is inhibited. Hydrated moss placed under nitrogen in the dark shows a reduced capacity for ATP and protein synthesis, but polysomes are conser...

Phenotypic plasticity provides means for adapting to environmental unpredictability. In terms of accelerated development in the face of pond-drying risk, phenotypic plasticity has been demonstrated in many amphibian species, but two issues of evolutionary interest remain unexplored. First, the heritable basis of plastic responses is poorly established. Second, it is not known whether interpopul...

This work describes the course of the experiment aimed to microwave (MW) desiccation of masonry by MW plug-in bar antenna applied to various types of brickwork. Experiment was carried on in the masonry manufactured from solid bricks, modern hollow brick form-pieces THERM and from aerated concrete blocks YTONG. Results of this experiment should determine what type of MW desiccation method is the...

Although aedine eggs are resistant to desiccation, little is known about this trait in Haemagogus species. In study, we assessed the desiccation resistance of Hg. spegazzinii eggs. The were collected using ovitraps over a period one week March 2020. positive pallets stored until experimentation and immersed solution water yeast for larval hatching subsequent species identification. emerged adul...

PREMISE OF THE STUDY Bryophytes include clades that incorporate constitutive desiccation tolerance, especially terrestrial species. Here we test the hypothesis that the opposing ecological strategy of desiccation tolerance, inducibility, is present in a desert moss, and address this hypothesis by varying rates of drying in a laboratory study. Desiccation tolerance is arguably the most important...

CO2-exchange of emersed plants and 0,-exchange of submersed plants were measured in 5 species of brown algae from different tidal heights on shores in Ireland and Helgoland (southern North Sea). The photosynthesis of emersed fucoids and Laminaria digitata increased as up to 25 % of tissue water was lost, but then declined with further desiccation. The relationship between decrease in photosynth...

We investigated the photosynthetic limitations occurring during dehydration and rehydration of Xerophyta humilis, a poikilochlorophyllous resurrection plant, and whether volatile and non-volatile isoprenoids might be involved in desiccation tolerance. Photosynthesis declined rapidly after dehydration below 85% relative water content (RWC). Raising intercellular CO(2) concentrations during desi...
