Characterization of the complete chloroplast genome of Lonicera similis (Caprifoliaceae)

Mitochondrial DNA. Part B. Resources, 2021
The complete chloroplast genome of Lonicera similis Hemsl. has been characterized by reference-based assembly using Illumina paired-end data. The circular complete cp genome is 155,463 bp in length, containing a large single copy (LSC) region of 89,282 ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Sulfur redirects carbon metabolism to optimize nitrogen utilization and promote andrographolide biosynthesis in Andrographis paniculata seedlings

Current Plant Biology
Sulfur (S) is an important mineral nutrient element that improves plant growth and secondary metabolism. S affects the biosynthesis of andrographolide in medicinal plant Androgaphis paniculata by regulating nitrogen (N) metabolism.

Mineral element contents and gene expression in Sophora tonkinensis during florescence

Biotechnology & Biotechnological Equipment, 2021
As a medicinal plant, Sophora tonkinensis is mainly distributed in Guangxi, Yunnan, Guizhou and northern Vietnam. In recent years, due to the strong demand for S. tonkinensis, wild resources have become decreased, which has placed great pressure on their

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Phylogenomic insights into the genus Tulipa (Liliaceae): Taxonomy, evolution, and biogeography

American Journal of Botany, EarlyView.
Abstract Premise Tulips are one of the best‐known geophytes, but their taxonomy remains convoluted and their evolutionary history poorly understood. Here, we used plastid genomes to identify some issues with current classification, understand the diversification history of the genus, and identify potential species linked to historical cultivation ...

Integrating developmental and macroevolutionary approaches reveals a staminodial origin of all alternisepalous organs in Caryophyllaceae

American Journal of Botany, EarlyView.
Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

A GATA transcription factor OfGATA9 positively regulates flower size of sweet osmanthus

BMC Genomics
Background Flower size significantly influences the visitation of pollinators in angiosperms, and is also a crucial trait that affects commercial value of ornament plants. Sweet osmanthus (Osmanthus fragrans) is an ornamental species characterized by its

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.
