Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

Journal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

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

New Phytologist, EarlyView.
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.

Glandular trichomes: the factory of artemisinin biosynthesis

Medicinal Plant Biology
Plant glandular trichomes serve as crucial secretory organs, responsible for the production, modification, and storage of various vital secondary metabolites, including medicinal natural products, while also playing a role in plant defense mechanisms ...

Leaf Micromorphology Aids Taxonomic Delineation within the Hypervariable Genus Metrosideros (Myrtaceae) on O\u27ahu

, 2018
Variation in leaf micromorphology can aid delimitation of taxonomically difficult groups. The woody genus Metrosideros (Myrtaceae) dominates Hawai\u27i\u27s native forests and comprises striking, predominantly infraspecific, macromorphological variation,

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, EarlyView.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

TSO1 functions in cell division during Arabidopsis flower development [PDF]

, 1997
We describe an Arabidopsis mutant, tso1, which develops callus-like tissues in place of floral organs. The tso1 floral meristem lacks properly organized three cell layers, and the nuclei of these cells are irregular in size and shape.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, EarlyView.
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),
