Infection of the soil-borne plasmodiophorid Polymyxa graminis transmits both Japanese soil-borne wheat mosaic virus (JSBWMV) and the barley yellow mosaic virus (BaYMV) to barley, but their interaction during an episode of their co-infection has not been characterized to date. Here, we present an analysis of the titer of JSBWMV and BaYMV in plants of winter barley growing over a five-month period from late fall until mid-spring. Although JSBWMV was detectable in the plants' roots four weeks earlier than BaYMV, the translocation of both viruses from the root to the leaves occurred nearly simultaneously. Both viruses were co-localized in the roots, leaf sheathes, and leaf blades; however, in some stripes of leaf veins where infection by JSBWMV was prominent, BaYMV was not detectable. A substantial titer of both viruses persisted until early spring, after which JSBWMV became more prominent, being in a range of 10 to 100 times abundant of BaYMV. However, JSBWMV was only able to infect a single wheat accession (cv. Norin 61), whereas all of the wheat entries assayed appeared to be immune to BaYMV infection. Overall, our findings highlight the importance of resistance mechanisms against soil-borne viruses in cereal crops, expanding our understanding of plant-virus interactions and potentially informing strategies for crop protection against viral pathogens.</p>","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plants can experience different types of abiotic stresses, either individually or in combination. Sometimes, more than one stress event may occur simultaneously or one after another during the lifecycle of the plant. In general, key survival strategies for stress tolerance may differ from one stress to another. However, at the molecular level, evolutionarily conserved protein kinase SUCROSE NONFERMENTING 1 (SNF1)-related protein kinase (SnRK) gene family members, comprising SnRK1, SnRK2, and SnRK3 gene families, play a key role in different types of stress and adaptive responses. SnRK gene family members can act as master regulators and regulate the central metabolism of plants, which determines the energy distribution in either survival or growth/developmental processes. The key mechanism of SnRK-mediated regulation is associated with the phosphorylation of downstream genes, which either induces or dampens the function of target proteins. This may be crucial for maintaining differential morpho-physiological and biochemical processes in plants, including potassium signalling, ROS homeostasis, sugar signalling, and energy homeostasis. Furthermore, phosphorylation sites associated with different targets were also reviewed, which showed that SnRK-mediated phosphorylation of Serine and Threonine residues of the target protein is a site-specific event, where the target consists of specific amino acid sequences, including RXXS/T, Serine-threonine rich regions, or AMPK/SNF1 types.

By monitoring the expression patterns of these genes throughout the whole growth period, we identified two candidate genes, StWRKY70 and StNAP, which may play pivotal roles in leaf senescence.

The results showed that exogenous sugars enhanced the accumulation of soluble sugar and starch while increasing the enzyme activity related to carbohydrate metabolism.
