Salicylic Acid and Shade Avoidance

In response to shading, plants undergo a suite of developmental and physiological responses known as shade avoidance. In agricultural settings, dense planting can cause shade avoidance responses, thereby reducing yields due to changes in carbon allocation that favor stem elongation over seed, fruit,…

Temperature-Responsive RNA Metabolism Proteins in Algae

Global climate change is currently affecting the growth and photosynthetic capacities of microalgae, which are major contributors to carbon fixation on Earth. The consequences of global climate change have already had dramatic effects on aquatic ecology. For example, thermal changes have led to coral…

The H+/K+ Antiporters of Endosomal Membranes

The plant endomembrane system is comprised of the endoplasmic reticulum (ER), the Golgi complex, trans-Golgi network (TGN), pre-vacuolar compartment (PVC) and vacuoles. The endomembrane system, by enabling protein modification and sorting, plays important roles in cell polarity, cytokinesis, cell wall…

Regulation of Cortical Microtubule Array Patterns

The plant cortical microtubule array is a dynamic self-organizing structure that controls the mechanics of plant growth by guiding the deposition of wall materials. While much is known about the properties of individual microtubules, the mechanism by which plant cells organize the cortical array into…

Polyacetylene Biosynthesis in Carrot


Polyacetylenic lipids accumulate in various Apiaceae species after pathogen attack, suggesting 
that they are naturally occurring pesticides and potential targets for crop improvement. These chemicals are also of interest because they exhibit cytotoxic activity against human cancer cell lines and slow tumor…

Local and Systemic Metabolic Responses in Response to Light Stress

Not every leaf of a plant is subjected to the same light intensity or quality in nature. As a consequence, plants have evolved multiple signaling pathways to transduce light‐related signals between different leaves. These systemic acclimation processes optimize the overall light perception of the…

New Advances in the Imaging of Sugars

The in vivo imaging of sugars is useful for understanding how assimilated carbon, in the form of sugars, moves in plants and how this process is differentially regulated. Voothuluru et al. (10.1104/pp.18.00614) developed a gel-based enzyme-coupled colorimetric and fluorometric assay to image glucose…

Transcription Factors and Apple Drought Tolerance

Water deficit is one of the main limiting factors in apple (Malus × domestica) cultivation. Root architecture plays an important role in the drought tolerance of plants. Due to the difficulties associated with the visualization of root systems, however, there is currently a poor understanding of the…

Chloroplast Damage Triggers Autophagy

Under normal growth conditions, there is a constitutive or basal level of autophagy in plant cells that helps to recycle unnecessary cell contents. Autophagy provides essential building blocks (e.g. amino acids and fatty acids) and energy sources that promote cell homeostasis and survival. Autophagy…
