Heat stress induces organelle alterations in Macrocystis pyrifera gametophytes

open access: yesJournal of Phycology, EarlyView.
Abstract Kelp, brown macroalgae in the order Laminariales, provide ecosystem services vital to ocean biodiversity. However, kelp forests worldwide are declining due to abiotic stressors such as ocean warming. In this study, we present results from high‐resolution confocal microscopy and in vivo imaging system imaging using protocols developed to ...

Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

open access: yesJournal of Systematics and Evolution, EarlyView.
Using Angiosperms353 and plastid genome skimming approaches, the generic limits of Hyacinthinae were explored using DNA sequences to better understand their evolution. Floral morphology, a traditional generic delimiter, conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define similar groups to DNA.

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

open access: yesNew Phytologist, EarlyView.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

Soil phosphorus drives subcontinental patterns of carbon isotope discrimination across Australia

open access: yesNew Phytologist, EarlyView.
Summary Several transects have been established to study the sensitivity of carbon isotope discrimination (Δ13C) in woody plants to mean annual precipitation (MAP) across Australia. These have shown a surprising divergence in Δ13C‐MAP sensitivity among subcontinental regions.

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

open access: yesNew Phytologist, EarlyView.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Polyphenol oxidase depletion in Nicotiana benthamiana enhances recombinant protein purification and preserves native protein integrity

open access: yesNew Phytologist, EarlyView.
Polyphenol oxidases (PPOs) depletion preserves endogenous proteins at their predicted molecular weights and enhances detectable enzymatic activities. (a) Less RbcL crosslinking in ppo mutant of Nicotiana benthamiana. Leaf extracts were incubated for 1 h, separated on protein gels, stained with Coomassie or analyzed by Western blot with the anti‐RbcL ...
