Aims: We evaluated the impact of fungal endophyte symbiosis on the growth, ecophysiological and reproductive success of wheat exposed to heat and drought. Methods and Results: The resistance of pot-grown wheat to heat or drought stress was measured by quantifying efficiency of photosystem II (F v /F m ), plant height, average seed weight (ASW), total seed weight (TSW), water-use efficiency (WUE) as well as time to 50% germination and percentage germination of second-generation seeds produced under heat stress, drought stress or wellwatered conditions. The endophytic fungi tested increased wheat tolerance for drought and heat. Endophyte SMCD 2206 was the most beneficial, followed by SMCD 2210 and 2215. Surprisingly, second-generation seeds produced by drought-stressed wheat colonized by SMCD 2206, 2210 or 2215 had decreased WUE relative to those produced by endophyte-free, drought-stressed plants. However, these seeds germinated more rapidly than those produced by endophyte-free, stressed parental plants. Conclusions:The tested consortium of endophytes has the potential to improve wheat adaptation to heat and drought. Significance and Impact of the Study: The capacity of endophytes to increase wheat tolerance for abiotic stress and to improved germination in endophytefree second-generation seeds arising from stressed plants could be applicable to agriculture. The mechanisms by which intergenerational endophyte-mediated affects occurs warrant further research.

“…The negative relationship observed with leaf 13 C under WW is common because according to Condon et al (2004), under well-watered conditions, genotypes with lower 13 C tend to grow slower than genotypes with higher 13 C, resulting in lower grain yield. Some studies (Anyia et al, 2007;Khazaei et al, 2008;Misra et al, 2006;Mohammady et al, 2009;Wahbi and Shaaban, 2011) have also reported negative relationships between 13 C and WUE under WW conditions while others (Araus et al, 1998;Araus et al, 2003;Kumar et al, 2011;Yasir et al, 2013) have reported positive correlations in small grain crops. There are, however, more inconsistencies regarding the relationship of 13 C with WUE and/or grain yield under WW.…”

“…Wheat had a strong relationship between Δ 13 C and water-use efficiency (Farquhar and Richards 1984). Stable carbon isotope studies in wheat have led to debate as to whether Δ 13 C is an accurate predictor of grain yields (Farquhar and Richards 1984;Ehdaie and Waines 1994;Monneveux et al 2005;Mohammady et al 2009).…”

δ13Cp Values from Radiocarbon-Dated Plant Matter as an Important but Underexploited Resource for Terrestrial Paleoclimate Analysis and Archaeology

Variation in stable carbon isotope ratios in C 3 plants can be influenced by climatic and environmental factors. For archaeologists, who regularly collect the measured values of these data as a part of the radiocarbon date reporting process, there is promise in using these data to create a local record of paleoclimatic change relevant to their study areas. Plant δ 13 C can be expressed as Δ 13 C values (carbon isotopic discrimination) that can be used in modern experimental studies for stronger paleoclimatic/paleoenvironmental interpretations. As values of Δ 13 C vary in different species, taxonomic information is necessary for interpretation. In the present study, a record of Irish oak δ 13 C data are used to construct a local climate history for Ireland. Wetter periods in Ireland inferred from δ 13 C data correspond to warmer Northern Hemisphere temperatures, in agreement with climate models. Values of δ 13 C from other species are used to illustrate the importance of using data from taxa with known relationships between climate and stable carbon isotope fractionation.
