Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Exploring plant tolerance to biotic and abiotic stresses [PDF]

, 2007
Plants are exposed to many stress factors, such as drought, high salinity or pathogens, which reduce the yield of the cultivated plants or affect the quality of the harvested products. Arabidopsis thaliana was used as a model plant to study the responses

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection

New Phytologist, EarlyView.
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

Pathogenic fungus Ustilago maydis exploits the lateral root regulators to induce pluripotency in maize shoots

New Phytologist, EarlyView.
Summary Biotrophic plant–pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all aerial parts of maize. However, the responsible gall‐inducing effectors and corresponding plant signaling pathway(s) remain largely unknown. Using

Cell‐type‐specific gating of gene regulatory modules as a hallmark of early immune responses in Arabidopsis leaves

New Phytologist, EarlyView.
Summary In plants, multiple cell types contribute to immunity, but what division of labor exists among cell types when immunity is activated? We compared, at single‐cell resolution, the response of Arabidopsis thaliana leaf cells during pattern‐triggered and effector‐triggered immunity (PTI/ETI), sampled at 3 and 5 h after infection with Pseudomonas ...

A Phylogenetic Analysis of the Genus Fragaria (Strawberry) Using Intron-Containing Sequence from the ADH-1 Gene [PDF]

, 2014
The genus Fragaria encompasses species at ploidy levels ranging from diploid to decaploid. The cultivated strawberry, Fragaria×ananassa, and its two immediate progenitors, F. chiloensis and F. virginiana, are octoploids.

B‐GATA factors are required for nitrogen‐responsive growth in Physcomitrium patens and Arabidopsis thaliana

New Phytologist, EarlyView.
Summary We hypothesized that B‐GATA family transcription factors have important roles in growth regulation in moss. We analyzed B‐GATA family transcription factor mutants from Physcomitrium patens and Arabidopsis thaliana to assess growth, gene expression, and cytokinin‐related processes under varying nitrogen conditions.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, EarlyView.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),

Engineering next‐generation crops through CRISPR‐mediated horizontal gene transfer

New Phytologist, EarlyView.
Summary Crops increasingly face overlapping stresses such as heat, drought, salinity, and pathogens that conventional breeding or genome editing rarely overcome in combination. To address this, we propose CRISPR‐enabled horizontal gene transfer (CRISPR‐HGT) as a programmable framework that recreates the evolutionary process by which plants historically

Metabolo‐Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline‐Alkali and Low‐Temperature Stress in the Field

Plant Biotechnology Journal, EarlyView.
ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions
