Abstract:
... Though numerous studies have investigated optimal locations for biorefineries given the availability of feedstock supplies, few have considered that these supplies could vary over time, thereby potentially failing to meet feedstock requirements. In this paper, we develop a process for identifying a shortlist of five potentially viable biorefinery sites in Alberta, and then consider the stochastic ...

Abstract:
... BACKGROUND: Crop yield is dependent on climate conditions, which are becoming both more variable and extreme in some areas of the world as a consequence of global climate change. Increased precipitation and flooding events are the cause of important yield losses due to waterlogging or (partial) submergence of crops in the field. Our ability to screen efficiently and quickly for varieties that have ...

Abstract:
... Heading date is a key agronomic trait affecting crop yield. In rice, Early heading date 1 (Ehd1) is an important B‐type response regulator in determination of heading date. Although many regulatory factors of Ehd1 expression have been functionally characterized, the direct regulators of Ehd1 largely remain to be identified. Here, we identified a new regulator of Ehd1, OsRE1, that directly binds to ...

Abstract:
... Strigolactones (SLs) are plant hormones that suppress shoot branching through perception by their receptor protein DWARF 14 (D14). The artificial regulation of SL signaling has been considered a potent agricultural technique because plant architecture is strongly related to crop yield. In this communication, we describe the development of a small-molecule D14 inhibitor that functions at sub-microm ...

Abstract:
... Energy conservation is an increasingly important issue in greenhouse production. Since higher energy input usually produces higher crop yields, crop yield and energy consumption must be carefully traded off. Generally, at any instant, the heating energy demand and crop yield depend on an interior temperature setpoint. Good, dynamically determined greenhouse climate setpoints not only improve crop ...
