Effect of Nitrogen Treatment on the Physico‐Chemical and Functional Properties Intermediate Wheatgrass (Thinopyrum intermedium) Grown in Different Locations

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Intermediate wheatgrass (IWG), a new perennial crop, is being explored for food applications; however, nitrogen application effects on its properties have not been investigated. This study evaluated the effects of applying 90 kg ha−1 of nitrogen in spring or fall seasons on the properties of IWG grown in Minnesota and

In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio

Chemie Ingenieur Technik, EarlyView.
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Making Two out of One: Kinesin Motors Driving Plant Cell Division

Cytoskeleton, EarlyView.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...
