Oxidative System

In recent years salicylic acid (SA) has been the focus of intensive research due to its function as an endogenous signal mediating role in defense responses after pathogen attack. SA antagonizes gene induction by the stress signaling molecule jasmonic acid (JA). It has also been found that SA plays a role during the plant responses to abiotic stresses. The discovery of its targets and understanding of its mechanism of the action in physiological and molecular processes could help in the sustainable plant productivity. Present report focused on various survival strategies of plants under changing environment and the role of SA in cross-talk signaling, osmoregulation, anti-oxidative system and induction of protein kinases under adverse environmental conditions.

Rainfall Regimes

Climate models project overall a reduction in rainfall amounts and shifts in the timing of rainfall events in mid-latitudes and sub-tropical dry regions, which threatens the productivity and diversity of grasslands. Arbuscular mycorrhizal fungi may help plants to cope with expected changes but may also be impacted by changing rainfall, either via the direct effects of low soil moisture on survival and function or indirectly via changes in the plant community. In an Australian mesic grassland (former pasture) system, we characterised plant and arbuscular mycorrhizal (AM) fungal communities every six months for nearly four years to two altered rainfall regimes: i) ambient, ii) rainfall reduced by 50% relative to ambient over the entire year and iii) total summer rainfall exclusion. Using Illumina sequencing, we assessed the response of AM fungal communities sampled from contrasting rainfall treatments and evaluated whether variation in AM fungal communities was associated with variation in plant community richness and composition. We found that rainfall reduction influenced the fungal communities, with the nature of the response depending on the type of manipulation, but that consistent results were only observed after more than two years of rainfall manipulation. We observed significant co-associations between plant and AM fungal communities on multiple dates. Predictive co-correspondence analyses indicated more support for the hypothesis that fungal community composition influenced plant community composition than vice versa. However, we found no evidence that altered rainfall regimes were leading to distinct co-associations between plants and AM fungi. Overall, our results provide evidence that grassland plant communities are intricately tied to variation in AM fungal communities. However, in this system, plant responses to climate change may not be directly related to impacts of altered rainfall regimes on AM fungal communities. Our study shows that AM fungal communities respond to changes in rainfall but that this effect was not immediate. The AM fungal community may influence the composition of the plant community. However, our results suggest that plant responses to altered rainfall regimes at our site may not be resulting via changes in the AM fungal communities.

Selection Of

The bibliography brings together more than 250 scientific papers and books written by Alwyne (Wyn) Wheeler over fifty years, from 1955–2006. This chronological list shows that from the beginning his research followed three themes: taxonomy of historically important fish collections; identification and distribution of the British and European fish fauna ; the status of British fishes in a changing environment. Until the mid-point in Wyn's career he published regularly on the identification of fish remains in archaeological sites in Britain and Europe. Wyn also wrote under an alias, Allan Cooper, and these have been listed separately. The bibliography concludes with a selection of the regular columns he contributed to angling magazines.
