Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

open access: yesNew Phytologist, EarlyView.
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

Phenylalanine 15N enrichment likely indicates fungal‐derived organic nutrient acquisition in mycoheterotrophic plants across fungal guilds

open access: yesNew Phytologist, EarlyView.
Summary Beyond fully mycoheterotrophic plants, many green plants may also obtain carbon from fungal partners. However, bulk stable isotope analyses often lack sufficient resolution in arbuscular mycorrhizal and rhizoctonia‐associated orchid systems, limiting inference of fungal‐derived organic nutrient acquisition.

Joint Routing and STDMA-based Scheduling to Minimize Delays in Grid Wireless Sensor Networks [PDF]

open access: yes, 2014
In this report, we study the issue of delay optimization and energy efficiency in grid wireless sensor networks (WSNs). We focus on STDMA (Spatial Reuse TDMA)) scheduling, where a predefined cycle is repeated, and where each node has fixed transmission ...

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

open access: yesNew Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

Improved mesophyll–bundle sheath connectivity is achieved via different mechanisms in C2 vs C4 Alternanthera

open access: yesNew Phytologist, EarlyView.
Leaf anatomy and biochemistry of C3, C2, and C4 plants. Summary Connectivity between mesophyll (M) and bundle sheath (BS) cells must improve during the evolution of C4 photosynthesis to facilitate large metabolite fluxes between these cell types, but the trait combinations that enhance M–BS connectivity and the points at which these enhancements occur ...

Rooting Conifer Genetic Research: An Accessible and Efficient Transformation System

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Conifers serve as the cornerstone of global forest ecosystems, yet their genetic transformation faces notorious challenges. To overcome the intrinsic resistance of conifer adventitious roots to Agrobacterium/Rhizobium‐mediated transformation, we systematically and iteratively engineered the binary vector by introducing chimeric Ri plasmid ...

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Mycorrhizal specificity of fully mycoheterotrophic Yoania in Taiwan and China and novel natural abundance stable isotope patterns

open access: yesPlant Biology, EarlyView.
Three species of the mycoheterotrophic orchid genus Yoania found in Taiwan and China are associated with a single taxonomic unit of white‐rot fungus from the genus Physisporinus and exhibit a stable isotope pattern distinct from other fully mycoheterotrophic (FMH) orchids associated with wood‐decaying fungi.
