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 ...

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 ...

Light signaling controls chloroplast pyruvate metabolism through the STF1/2–PKP1 module in soybean

Journal of Integrative Plant Biology, EarlyView.
In soybean, light‐responsive proteins switch on GmPKP1, which boosts chloroplast pyruvate production. This increases pigments, photosynthesis, seed oil, pod number, and yield, revealing a new way that light boosts crop productivity. ABSTRACT Light signaling coordinates plant development with metabolism, but the link between photoreceptors and ...

An alfalfa MYB71‐centered activation–attenuation module fine‐tunes redox homeostasis and drought tolerance in Medicago sativa

Journal of Integrative Plant Biology, EarlyView.
In alfalfa, the transcription factor MsMYB71 activates the peroxiredoxin Q gene MsPrxQ, which helps remove harmful reactive oxygen species and improves drought tolerance. The WD40‐repeat protein MsPRL1 and the Cullin‐family scaffold protein MsCUL4 interact with and limit MsMYB71 accumulation and activity in an activation‐attenuation mechanism ...

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.

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.

Visualising Physcomitrium patens protoplasts with full‐rotation soft X‐ray tomography

Journal of Microscopy, EarlyView.
Abstract Soft X‐ray tomography (SXT) is a label‐free, high‐resolution imaging modality that is optimal for 3D visualisation of whole hydrated cells. Although SXT has been extensively used to study remodelling in more than 130 mammalian cell lines, its application to plants remains largely unexplored. In this study, we present the first approach at full‐
