The Wheat CRK‐RLCK‐MAPKs Signalling Module Confers High‐Temperature All‐Stage Resistance to Stripe Rust

Plant Biotechnology Journal, EarlyView.
ABSTRACT As global warming continues, rising temperatures significantly alter the interactions between wheat and the stripe rust pathogen Puccinia striiformis f. sp. tritici (Pst). Utilising high‐temperature all‐stage (HTAS) resistance to Pst is a novel strategy for breeding climate and disease resilient wheat cultivars.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Simultaneous Detection of Three Bacterial Seed-Borne Diseases in Rice Using Multiplex Polymerase Chain Reaction

The Plant Pathology Journal, 2016
Burkholderia glumae (bacterial grain rot), Xanthomonas oryzae pv. oryzae (bacterial leaf blight), and Acidovorax avenae subsp. avenae (bacterial brown stripe) are major seedborne pathogens of rice. Based on the 16S and 23S rDNA sequences for A.

Regulatory network of hrp gene expression in Xanthomonas oryzae pv. oryzae

Journal of General Plant Pathology, 2014
Like other plant-pathogenic bacteria, Xanthomonas oryzae pv. oryzae, the causal agent of bacterial leaf blight of rice, has hrp genes that are indispensable for its virulence. The hrp genes are involved in the construction of the type III secretion (T3S) apparatus, through which dozens of virulence-related proteins, called effectors, are directly ...

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.

Functional Interplay Between Two Xanthomonas oryzae pv. oryzae Secretion Systems in Modulating Virulence on Rice

Molecular Plant-Microbe Interactions, 2007
The type II (T2S) and type III (T3S) secretion systems are important for virulence of Xanthomonas oryzae pv. oryzae, causal agent of bacterial leaf blight of rice. The T3S of gram-negative bacterial plant pathogens has been shown to suppress host defense
