Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Uncovering the role of the PPR protein PHOTOSYSTEM ONE BIOGENESIS FACTOR6 in splicing chloroplast group II introns

Journal of Integrative Plant Biology, EarlyView.
The P‐class pentatricopeptide repeat (PPR) protein PHOTOSYSTEM ONE BIOGENESIS FACTOR (PBF6) forms splicing complexes with other known splicing factors to facilitate chloroplast intron splicing. PBF6 cooperates with other PPR splicing factors to promote the splicing of the same intron through forming respective splicing complexes.

PHOTOSYNTHETHIC PARAMETER ASSESSMENT OF CORAL ZOOXANTHELLAE OF Acropora aspera AND Favites abdita USING MAXI I-PAM SYSTEM IN HERON ISLAND, GREAT BARRIER REEF, AUSTRALIA [PDF]

, 2006
Zooxanthellae, which reside inside the coral host, have been an essential component in coral ecosystem studies. While residing inside their host, zooxanthellae photosynthesize provide energy and nutrients to coral. Objectives are to observe the impact of

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

New 3-D Fluorescence Spectral Indices for Multiple Pigment Inversions of Plant Leaves via 3-D Fluorescence Spectra

Remote Sensing
High-sensitivity fluorescence monitoring has been widely used in agriculture and environmental science. However, the active fluorescence detection information of leaf segments mainly focuses on total chlorophyll, and the fluorescence information of ...

Beyond single cells: Ten years of commercial lattice light‐sheet microscopy

Journal of Microscopy, EarlyView.
Abstract Lattice light‐sheet microscopy (LLSM) enables gentle, rapid, volumetric fluorescence imaging of living biological systems. The technique employs Bessel beam interference to produce a light‐sheet which retains its thickness over a relatively large field‐of‐view compared to other light‐sheets.

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

Journal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Turnip mosaic virus utilizes the lipid droplet biogenesis machinery to facilitate its propagation in plants

New Phytologist, EarlyView.
Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions, including membrane remodeling during abiotic stress.

Imaging Spatial and Temporal Variation in Photosynthesis Using Chlorophyll Fluorescence

Chlorophyll fluorescence imaging provides a noninvasive rapid screen to assess the physiological status of a number of leaves or plants simultaneously. Although there are no standard protocols for chlorophyll fluorescence imaging, here we provide an example of routines for some of the typical measurements.
