Plant-to-plant defence induction in cotton is mediated by delayed release of volatiles upon herbivory.

Caterpillar feeding immediately triggers the release of volatile compounds stored in the leaves of cotton plants. Additionally, after 1 d of herbivory, the leaves release other newly synthesised volatiles. We investigated whether these volatiles affect chemical defences in neighbouring plants and whether such temporal shifts in emissions matter for signalling between plants.

The clove (Syzygium aromaticum) genome provides insights into the eugenol biosynthesis pathway.

The clove (Syzygium aromaticum) is an important tropical spice crop in global trade. Evolving environmental pressures necessitate modern characterization and selection techniques that are currently inaccessible to clove growers owing to the scarcity of genomic and genetic information. Here, we present a 370-Mb high-quality chromosome-scale genome assembly for clove.

Oxidative costs of cooperation in cooperatively breeding Damaraland mole-rats.

Within cooperatively breeding societies, individuals adjust cooperative contributions to maximize indirect fitness and minimize direct fitness costs. Yet, little is known about the physiological costs of cooperation, which may be detrimental to direct fitness. Oxidative stress, the imbalance between reactive oxygen species (by-products of energy production) and antioxidant protection, may represent such a cost when cooperative behaviours are energetically demanding.

[Single, immediate postoperative intra-vesical instillation (SI) compared to a single preoperative intra-vesical instillation of mitomycin C in non-muscle invasive bladder cancer (NMIBC). Phase II randomized trial].

Objective: A single immediate instillation of mitomycin C is recommended after a complete transurethral resection of the bladder (TURB) in low- and intermediate-risk patients with NMIBC. Actually, post-TURB instillation is seldom used due to logistical difficulties and surgical contraindications. Our aim was to compare patients with single pre-TURB intra-vesical instillation and patients with a single, immediate post-TURB intra-vesical instillation of mitomycin C.
