Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Low irradiance alters carbon metabolism and delays flower stalk development in two orchids

Biologia Plantarum, 2013
In Phalaenopsis, lowering irradiance has been used to delay flower stalk development but the accompanying biochemical changes remain poorly understood. We cultured two commercial Phalaenopsis-type orchids, Phalaenopsis cv.

Covalent dimerization of ribulose bisphosphate carboxylase subunits by UV radiation [PDF]

Biochemical Journal, 1996
The effect of UV radiation (UV-A, UV-B and UV-C) on ribulose bisphosphate carboxylase from a variety of plant species was examined. The exposition of plant leaves or the pure enzyme to UV radiation produced a UV-dependent accumulation of a 65 kDa polypeptide (P65).

OsCPN10a, cooperating with OsCPN20 and OsHSP60‐3B negatively regulate ABA signaling and enhance seed storability in rice

Journal of Integrative Plant Biology, EarlyView.
Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

Synechocystis PCC 6803 overexpressing RuBisCO grow faster with increased photosynthesis

Metabolic Engineering Communications, 2017
The ribulose-1,5-bisphosphate (RuBP) oxygenation reaction catalyzed by Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is competing with carboxylation, being negative for both energy and carbon balances in photoautotrophic organisms. This makes

X-ray structure of Galdieria Rubisco complexed with one sulfate ion per active site [PDF]

, 2002
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the reactions of carboxylation and oxygenation of ribulose-1,5-bisphosphate. These reactions require that the active site should be closed by a flexible loop (loop 6) of the large ...

Ribulose bisphosphate carboxylase/oxygenase in toluene-permeabilized Rhodospirillum rubrum [PDF]

Biochemical Journal, 1983
Toluene-permeabilized Rhodospirillum rubrum cells were used to study activation of and catalysis by the dual-function enzyme ribulose bisphosphate carboxylase/oxygenase. Incubation with CO2 provided as HCO3-, followed by rapid removal of CO2 at 2 degrees C and subsequent incubation at 30 degrees C before assay, enabled a determination of decay rates of

Temporal stability and spatial patterns of genetic diversity in populations of the climate‐vulnerable fucoid Scytothalia dorycarpa

Journal of Phycology, EarlyView.
Abstract Climate change is driving the loss of genetic diversity, potentially limiting species' capacity to adapt to environmental change. Detecting changes in genetic diversity requires replicated temporal data, which is lacking for most species. Here, we combined contemporary and historical specimens of the climate‐vulnerable fucoid Scytothalia ...

Invasive plants optimize leaf nitrogen allocation in photosynthesis

New Phytologist, EarlyView.
Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.
