The Trojan Horse Approach to Protein Jockeying
Blog, Research Blog, The Plant Cell, The Plant Cell: In BriefIn the decades since Agrobacterium tumefaciens was first used as a vector to deliver genetic material into plants (Zambryski et al., 1983), this powerful tool has provided important insights into the biological functions of countless gene products. However, this approach has its shortcomings; in addition…
Stretching Plants with Cellular Resolution
Research, The Plant Cell, The Plant Cell: In a Nutshell
Robinson et al. develop a method to measure mechanical properties of plant tissue with cellular resolution https://doi.org/10.1105/tpc.17.00753
Background: Plant growth is controlled by the extensibility of the cell wall and the turgor pressure inside. The spatial regulation of these properties…
Commentary: Is it ordered correctly? Validating genome assemblies by optical mapping
Blog, Plant Science Research Weekly, Research, Research BlogOne of the hardest parts of any sequencing project is putting the pieces together. Physical sequence alignments can be cross checked against genetic linkage maps when they are available, but what about for species without genetic linkage data? Udall and Dawe describe the use of optical mapping, using…
Update: Finite element modeling of shape changes in plant cells
Blog, Plant Physiology, Plant Physiology: Updates, Research, Research BlogBy Amir Bidhendi and Anja Geitmann
Abstract
Plant cells come in a striking variety of different shapes. Shape formation in plant cells is controlled through modulation of the cell wall polymers and propelled by the turgor pressure. Understanding the shaping aspects of plant cells requires knowledge…
Update: Advances in imaging plant cell dynamics
Blog, Plant Science Research Weekly, Research, Research BlogSince the days of Robert Hooke, microscopy has been one of the biologist’s most important tools, and continues to become ever more powerful. Komis et al. review recent advances in superresolution microscopy, particularly as they pertain to the dynamics of plant cells. Dynamic systems demand fast imaging,…

Blog, Plant Physiology, Plant Physiology: Updates, Research, Research BlogBy Jozef Samaj, George Komis, Dominik Novak, Miroslav Ovecka, Olga Samajova
Abstract
After the establishment of advanced fluorescence microscopy methods and the development of numerous fluorescent proteins it is possible to follow the organization and dynamics of most organelles and subcellular…
Persistent drought monitoring using a microfluidic-printed electro-mechanical sensor of stomata in planta
Blog, Plant Science Research Weekly, Research, Research BlogPersistent drought monitoring using a microfluidic-printed electro-mechanical sensor of stomata in planta
The study of stomatal dynamics is crucial for understanding photosynthetic gas exchange and plant hydraulics, but there are currently no methods for measuring the conductance of individual stomata…
Arabidopsis perfusion platform RootChip reveals local adaptations of roots
Blog, Plant Science Research Weekly, Research, Research BlogRoots are essential plant organs that need to respond and adapt to dynamic environments. It is still unknown if these adaptations are based on systemic or cell-based responses. Stanley and colleagues created the dual-flow-RootChip, a platform for the heterogeneous perfusion of Arabidopsis roots to…
Roots-eye view: Using microdialysis and microCT to non-destructively map root nutrient depletion and accumulation zones
Blog, Plant Science Research Weekly, Research, Research BlogPlant roots constantly engage in nutrient and water uptake for crop productivity. Increasing the nutrient uptake efficiency of roots will promote sustainable agriculture by decreasing the need for fertilizer applications. To achieve this task, we need to understand the physiology of intact roots in their…
