The basal medium was Murashige and Skoog’s medium containing 1 μM 2,4-dichlorophenoxyacetic acid and 0.1 μM benzyladenine, 3% sucrose, and 0.4 M mannitol. The protoplast division was highly stimulated by the addition of 50 mM Ca2+ ion but was totally inhibited by 50 mM Mg2+ ion. Inhibition by K+ and Na+ ions was in-between. By contrast, PCF formation, whose numbers were counted under a fluorescence inverted microscope after Aniline Blue staining for β-1,3-glucan (callose), was stimulated by both K+ and Ca2+ ions but inhibited by Mg2+ ion. After selecting Arabidopsis PCF using a micromanipulator, the sub-fibril ultrastructure was examined by transmission electron microscopy (TEM). The PCFs of Betula platyphylla and Larix leptolepis, cultured with 200 mM Ca2+ and 50 mM Mg2+ ions, respectively, after long-term storage and rehydration, were examined by TEM. The effects of different factors were discussed on PCF formation and sub-structures in different herbaceous and tree plant species.","PeriodicalId":410634,"journal":{"name":"Journal of Plant Studies","volume":"28 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the 2022 growing season, 96 fields from the five major sorghum production regions of Dosso, Maradi, Tahoua, Tillabéri, and Zinder were surveyed for foliar and panicle diseases. In each field, 40 plants were assessed using a W-shaped pattern to cover the whole field. A total of 19 diseases, including leaf blight, anthracnose, long smut, zonate leaf spot, bacterial leaf stripe, oval leaf spot, and rough leaf spot were documented. Leaf blight (100%) was detected in all the fields surveyed. In the regions of Dosso and Zinder, anthracnose was found in all the surveyed fields while oval leaf spot was detected in all surveyed fields in Maradi and Zinder. The highest mean incidence of leaf blight (95%) was recorded in the regions of Tahoua and Zinder while oval leaf spot (80%), anthracnose (56%), and gray leaf spot (25%) were highest in Maradi region. The highest mean severities of leaf blight (30%), long smut (29%), grain mold (18%), and anthracnose (13%) were recorded in Maradi region. The severity of head smut was 100% in all the regions where the disease was observed. Fields with incidence of 90% and above identified during the survey are considered as ‘hot spots’ for disease resistance screening. This work is significant because the information generated by the study can be utilized by sorghum workers, students, funding agencies and government officials to prioritize research projects.","PeriodicalId":410634,"journal":{"name":"Journal of Plant Studies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128044214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was carried out in four types of formations in the Sudanian zone of Burkina Faso to assess the contribution of plant species to climate change mitigation. The below-ground biomass of two species (Piliostigma reticulatum and Guiera senegalensis) was determined by the direct method. Three classes of subjects were determined and a total of 80 shrubs of P. reticulatum and 90 shrubs of G. senegalensis were completely excavated. The results showed that P. reticulatum measures about 0.49 to 2.10 m in height, 3.58 to 25 cm in circumference at the base of the trunk and stores 0.18 to 3.68 tC/ha in the root biomass (respectively after 3 years and 15 years) for a 3x3m plantation. In the 15-year fallow dominated by G. senegalensis stands, 3.93 tC/ha are stored by the underground biomass of G. senegalensis shrubs. Model fit showed that there is a good correlation between circumference at the base of the trunk and below-ground biomass for P. reticulatum. For G. senegalensis, it is the total height of the foot that is most correlated with the below-ground biomass. These results provide information on the carbon sequestration potential of these two species, and can thus help in the decision-making process for climate change adaptation and/or mitigation policies.","PeriodicalId":410634,"journal":{"name":"Journal of Plant Studies","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122115049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
