Article Abstract
The migratory plant-parasitic nematode is the pathogen of the pine wilt disease (PWD), causing serious damage to pine forests in China. During the process of plant resistance to multiple pathogens, plant immunity plays a key role. In this current study, the pathogen-associated molecular pattern (PAMP) BxCDP1 in has been identified, but the host target protein of BxCDP1 and its key amino acid region inducing the plant immunity have yet to be elucidated. We found that BxCDP1 could trigger superoxide production, HO production, and callose deposits. A RING-H2 finger protein 1 (RHF1) of was screened and characterized as a target protein of BxCDP1 by yeast two-hybrid and co-immunoprecipitation (Co-IP). Moreover, two peptides (namely M9 and M16) proved to be key regions of BxCDP1 to induce PAMP-triggered immunity (PTI) in , which also induced the expression of pathogenesis-related (PR) genes (, , and ) in and enhanced the resistance of the host to . These results indicate that BxCDP1 plays a critical role in the interaction between and , and both peptides M9 and M16 have the potential to be developed and utilized as immune inducers of pines against in future.
Bacterial leaf blight (BLB) caused by pv. () has shown a high incidence rate in rice fields in recent years. Rice resistance breeding is considered as the most effective method for achieving economical and sustainable management of BLB disease.
Background: Charcoal Rot (CR) poses a significant threat to mung bean crops by reducing yield, making the development of resistant varieties crucial for stable production and food security. This study evaluated 19 newly identified mung bean landraces using biochemical traits and SSR markers, revealing genetic variability, CR disease reactions, and traits influencing yield and resistance, which provide valuable insights for breeding CR-resistant, high-yielding varieties.
Methods And Results: Mung bean landraces were evaluated for their response to CR using 4 biochemical parameters, and 10 SSR markers to assess genetic variability and disease resistance.
Fruit is an essential part of the human diet, and postharvest fungal diseases are the major cause of fruit postharvest losses worldwide. Pathogen-associated molecular patterns (PAMPs) are important elicitors from microbes, and the recognition between microbial PAMPs and plant receptors leads to PAMP-triggered immunity. Here, we identified a PAMP, PdEIX, that is an important protein elicitor with plant immunity-inducing activity, from the citrus green mold pathogen .
In Arabidopsis thaliana, the transcription factors WRKY7, WRKY11 and WRKY17 act as negative defence regulators against Pseudomonas syringae pv. tomato (Pst) DC3000. However, their coordinated regulation of gene expression has yet to be fully explored.
Background: Sugar beets (Beta vulgaris L.) are grown worldwide and suffer economic loss annually due to curly top disease caused by the beet curly top virus (BCTV). The virus is spread by the beet leafhopper (BLH), Circulifer tenellus Baker.
