New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.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.

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),

Microclimate drives demographic compensation in a narrow endemic tropical species
New Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

New Phytologist, Volume 250, Issue 2, Page 988-1003, April 2026.Summary Circular RNAs (circRNAs) are single‐stranded, covalently closed RNA molecules that arise from exon back‐splicing. The identification and function investigation of circRNAs have been comprehensively explored in plants, however, the regulatory mechanisms are largely unknown.

How state transitions balance photosynthetic electron transport in plants – a quantitative study
New Phytologist, Volume 250, Issue 1, Page 209-229, April 2026.Summary In plants, the process of state transition regulates the allocation of sunlight energy between Photosystem II (PSII) and PSI. However, the implications of state transitions for harmonizing electron transport rates between photosystems, and a full quantitative picture of this process, remain underexplored.

Structural and computational studies of herbicides active via photosystem II.
, 1991 This Thesis aims to increase the understanding of the way in which herbicides inhibit plant photosynthesis by interference at the site of photosystem II. Two structurally dissimilar series of compounds, provided by Schering Agrochemicals (Saffron Walden, U.K.), one rigid, one flexible, both series showing varying herbicidal activity, were submitted to ...
