“…Valsa canker, caused by Valsa species, is one of the most serious fungal diseases in apple and pearproducing areas in China and East Asia (Cui et al, 2022). Investigations on the resistant mechanism and related key genes are thus critical for the genetic improvement on the Valsa canker resistance of fruit crops in Malus and Pyrus species.…”

Wall-associated kinases (WAKs) were determined the role for perceiving pathogenic signals and initiation of plant immune responses. However, the roles of the family members in host resistance against Valsa canker, a serious fungal disease of apple and pear, are largely unknown. Here, we identified MbWAK1in Malus baccata, a resistant germplasm, was differentially expressed during infection by Valsa mali (Vm) and multiple stress-related signals. Over-expression MbWAK1 enhanced the Valsa canker resistance of apple and pear fruits and ‘Duli-G03’ (Pyrus betulifolia) suspension cells. A large number of phloem, cell wall and lipid metabolic process-related genes were differentially expressed during overexpressed suspension cells lines respond to Valsa pyri (Vp) signals. Among these, the expression of xyloglucan endotransglucosylase/hydrolase gene PbeXTH1 and sieve element occlusion-related gene PbeSEOR1 were significantly inhibited. Transient expression of PbeXTH1 or PbeSEOR1 obviously compromised the expressional induction of MbWAK1 and the resistance contributed by MbWAK1. In addition, MbWAK1 interacted with PbeXTH1 and PbeSEOR1, as well as several patterns recognize receptors, such as MdBAK1 and MdCERK1. Our results enriched the molecular mechanisms for MbWAK1 against Valsa canker and resistant breeding.

“…The most frequently used are support vector machines (SVM) [27] (which are noise-tolerant and high-precision, but not suitable for large data and bear a low processing rate) and neural networks. These include artificial neural networks (ANNs) [28], which reliable, convenient and suitable for processing noisy data and solving complex problems but require large number of training samples and processing time; convolutional neural networks (CNNs) [29]; backpropagation neural networks (BPNNs); and random forest (RF) with its related representative, the decision tree. Special indexes, discriminative analysis, extreme learning machine (ELM), joint sparse representation-based classification (JSRC); pixel-wise (PW); and self-organizing maps (SOM).…”

Plant diseases of an infectious nature are the reason for major economic losses in agriculture throughout the world. The early, rapid and non-invasive detection of diseases and pathogens is critical for effective control. Optical diagnostic methods have a high speed of analysis and non-invasiveness. The review provides a general description of such methods and also discusses in more detail methods based on the scattering and absorption of light in the UV, Vis, IR and terahertz ranges, Raman scattering and LiDAR technologies. The application of optical methods to all parts of plants, to a large number of groups of pathogens, under various data collection conditions is considered. The review reveals the diversity and achievements of modern optical methods in detecting infectious plant diseases, their development trends and their future potential.

Wall‐associated kinases (WAKs) have been determined to recognize pathogenic signals and initiate plant immune responses. However, the roles of the family members in host resistance against Valsa canker, a serious fungal disease of apples and pears, are largely unknown. Here, we identified MbWAK1 in Malus baccata, a resistant germplasm differentially expressed during infection by Valsa mali (Vm). Over‐expression of MbWAK1 enhanced the Valsa canker resistance of apple and pear fruits and ‘Duli‐G03’ (Pyrus betulifolia) suspension cells. A large number of phloem, cell wall, and lipid metabolic process‐related genes were differentially expressed in overexpressed suspension cell lines in response to Valsa pyri (Vp) signals. Among these, the expression of xyloglucan endotransglucosylase/hydrolase (XTH) gene PbeXTH1 and sieve element occlusion B‐like (SEOB) gene PbeSEOB1 were significantly inhibited. Transient expression of PbeXTH1 or PbeSEOB1 compromised the expressional induction of MbWAK1 and the resistance contributed by MbWAK1. In addition, PbeXTH1 and PbeSEOB1 suppressed the immune response induced by MbWAK1. Our results enriched the molecular mechanisms for MbWAK1 against Valsa canker and resistant breeding.
