Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Two New Species of Tricoma (Tricoma) (Nematoda: Desmoscolecidae) from Korean Subtidal Sediments, with Notes on Labial Ultrastructure

Journal of Marine Science and Engineering
This paper reports two newly discovered species of Tricoma (Tricoma)—T. (T.) discrepans sp. nov. and T. (T.) parasetosa sp. nov.—obtained from the subtidal sediments at a depth of 13 m around Jindo Island, Korea. Tricoma (T.) discrepans sp. nov. differs from its congeners in possessing 40–41 main rings, an uncovered first main ring, large vesicular ...

A chromosome‐scale genome assembly of Hordeum erectifolium: genomic, transcriptomic and anatomical adaptations to drought in a wild barley relative

New Phytologist, Volume 250, Issue 4, Page 2652-2669, May 2026.
Summary Wild crop relatives are valuable genetic resources for improving stress adaptation in cultivated species, but their effective use depends on high‐quality reference genomes integrated with phenotypic and molecular datasets. Hordeum erectifolium, a wild relative of barley (H.

Ecological predictors of plant responses to sequential herbivory: a meta‐analysis

New Phytologist, Volume 250, Issue 2, Page 1128-1140, April 2026.
Summary Plants evolved alongside herbivores for over 400 million years and show remarkable plasticity in responses to attack by multiple herbivores. However, it is often debated which herbivore traits predict plant responses and it is poorly understood how plant life‐history traits contribute to the variation observed in plant responses.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, Volume 250, Issue 2, Page 1141-1156, April 2026.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),

Masters of perception: phosphorylation‐dependent signaling in plants

New Phytologist, Volume 250, Issue 1, Page 89-94, April 2026.
Summary Plants are masters of perception, reacting to a myriad of biochemical and physical cues in a constantly changing environment. Plants rely on local cell‐based signal processing to perceive and react sufficiently fast to a multitude of stimuli. The ability to respond quickly is crucial for sustaining growth, defense, and metabolism and thereby ...
