Biophysical and economic implications for agriculture of +1.5° and +2.0°C global warming using AgMIP Coordinated Global and Regional Assessments por Ruane, Alex C, Antle, John, Elliott, Joshua, Folberth, Christian, Hoogenboom, Gerrit, Mason-D'Croz, Daniel, Müller, Christoph, Porter, Cheryl H., Phillips, Meridel M., Raymundo, Rubí M., Sands, Ronald D., Valdivia, Roberto, White, Jeffrey W., Wiebe, Keith D., Rosenzweig, Cynthia

“…The result is upward pressure on prices and area expansion for maize and wheat Triticum aestivum, while soy prices and area decline (results for rice Oryza sativa are mixed). An example global mitigation strategy encouraging bioenergy expansion is more disruptive to land use and crop prices than the climate change impacts alone, even in the +2.0°C scenario which has a larger climate signal and lower mitigation requirement than the +1.5°C scenario. …”

Cytokinin increases vegetative growth period by suppressing florigen expression in rice and maize por Cho, Lae-Hyeon, Yoon, Jinmi, Tun, Win, Baek, Gibeom, Peng, Xin, Hong, Woo-Jong, Mori, Izumi C., Hojo, Yuko, Matsuura, Takakazu, Kim, Sung-Ryul, Kim, Sun-Tae, Kwon, Soon-Wook, Jung, Ki-Hong, Jeon, Jong-Seong, An, Gynheung

“…Increasing the vegetative growth period of crops can increase biomass and grain yield. In rice (Oryza sativa), the concentration of trans ‐zeatin, an active cytokinin, was high in the leaves during vegetative growth and decreased rapidly upon induction of florigen expression, suggesting that this hormone is involved in the regulation of the vegetative phase. …”
