I suspect if we asked someone to describe a fossil we’d hear a lot about dinosaur bones. Certainly, science museums are full of fossilized animal remains, which have greatly informed our understanding of animal evolution. Plant fossils similarly are rich sources of information about plant evolution and evolutionary development (evo-devo), as highlighted here by Hetherington. […]
This article poses the interesting question of whether we can use our knowledge of plant cell wall-modifying, carbohydrate-active enzymes to produce biobased materials. Specifically, the authors point out that much of the hemicellulose contained in agricultural and wood fiber could provide a starting point for making useful products such as aerogels, films, and coatings. Compared […]
Many studies have demonstrated the importance of volatile organic compounds (VOCs) in communication between plants. VOCs emitted by a plant damaged by herbivory promote defenses in nearby plants. It is thought that these compounds may have originated as intra-plant signals, capable of moving long-distances faster than signals through the plant vascular system, with the inter-plant […]
Although clusters of functionally related genes are common in prokaryotes, until recently it was thought that they were not a feature of eukaryotic genomes. However, several studies have identified biosynthetic gene clusters (BGCs) in plants. Many of these gene clusters include sets of enzymes that act sequentially in the production of specialized metabolites, such as […]
The hourglass model of embryogenesis was proposed in the 1990s, and extended to green plants and fungi in the 2010s. During animal embryogenesis, the very earliest stages (post fertilization) are morphologically quite different from each other, and the later stages are quite different, but in the middle of embryogenesis there is a period, called the […]
Spotlight: The role of fossils for reconstructing the evolution of plant development I suspect if we asked someone to describe a fossil we’d hear a lot about dinosaur bones. Certainly, science museums are full of fossilized animal remains, which have greatly informed our understanding of animal evolution. Plant fossils similarly are rich sources of information […]
Don’t miss this exciting Virtual Issue from New Phytologist on “plant-microbe-microbe” interactions. That’s not a typo – many of the articles address the signals that coordinate such multi-factorial interactions, as there is a growing recognition that interrelations between microbes influence how they interaction with plants (see also the review below by Mesny et al.). This […]
Auxin is an extremely important plant hormone that must be precisely controlled. Auxin-like herbicides have been developed that are often more stable than the natural auxins, thus their application can damage the plant. Here, Schulz, Ung et al. investigated how these auxin herbicides move in plant tissues. The authors investigated the interactions of the well-known […]
In acidic soils, aluminum (Al) toxicity is a major problem that causes a dramatic arrest in root elongation. Aluminum tolerance can include the secretion of organic acids and the sequestration of Al in internal cellular compartments. Here, Dong et. al shed light on a new pathway that alleviates the inhibition of cell elongation in the […]
