Transgenic maize phosphoenolpyruvate carboxylase alters leaf–atmosphere CO2 and 13CO2 exchanges in Oryza sativa by Giuliani, Rita, Karki, Shanta, Covshoff, Sarah, Lin, Hsiang-Chun, Coe, Robert A., Koteyeva, Nuria K., Evans, Marc A., Quick, W. Paul, von Caemmerer, Susanne, Furbank, Robert T., Hibberd, Julian M., Edwards, Gerald E., Cousins, Asaph B.

“…Therefore, to address this issue, leaf–atmosphere CO2 and 13CO2 exchanges were measured, both in the light (at atmospheric O2 partial pressure of 1.84 kPa and at different CO2 levels) and in the dark, in transgenic rice expressing ZmPEPC and wild-type (WT) plants. …”

Interactions of rice seedlings with bacteria isolated from rice roots by Prayitno, J., Stefaniak, J., McIver, J., Weinman, J.J., Dazzo, F.B., Ladha, J.K., Barraquio, W., Yanni, Y.G., Rolfe, B.G.

“…They were not, however, detected migrating into other parts of the leaf from the original site of pressure-infiltration, indicating that the bacterial ability to migrate within the lateral roots is not matched by a similar capacity in rice leaves. …”

Correlation between carbon isotope discrimination and transpiration efficiency in lines of the c-4 species sorghum bicolor in the glasshouse and the field by Henderson, S., Caemmerer, S. von, Farquhar, G.D., Wade, L., Hammer, G.

“…The observed correlations were consistent with theory, opposite to those for C3 species, and showed that variation in Δd was an integrated measure of long-term variation in the ratio of intercellular to ambient CO2 partial pressure, pi/pa. Detailed gas exchange measurements of carbon isotope discrimination during CO2 uptake, ΔA, and pi/pa were made on leaves of eight S. bicolorlines. …”

Critical topics in Bangladesh’s and Nigeria’s food system related policies: An exploratory policy review by Bakker, S., Beune, R., Herens, M., Pittore, K.

“…This in combination with a growing population and rapid urbanization leads to inequalities between rural and urban areas, between the North and South of the country and between women and men, and the risk of conflict situations put the food system under pressure. The triple burden of nutrition is well recognised, as well as food safety issues. …”

Migration in rural Burkina Faso by Wouterse, Fleur Stephanie

“…In addition, a reduction in household size means less consumption pressure on the household. Considering the welfare impacts of both forms of migration and the wider policy environment, your assignment is to consider how policy could be directed toward enhancing the role of migration in local development.…”

Development of an eco-hydrological distance index and improved environmental flow assessment by integrating ecological monitoring and hydrological modeling by Arrighi, C., De Simone, M., Checcucci, G., Bonamini, I., Bartalesi, S., Simoncini, C., Castelli, F.

“…The findings underscore that statistical-hydrologic methods alone fail to capture the complex dynamics between flow regimes and ecological status, especially under high human pressure. In fact, when human pressures on water quality are significant, the restoration of natural flows would not be enough to achieve ecological status objectives.…”
