Repeated Isolation of the pathogen from the infected leaves of Rumex crispus yielded the fungus which on the basis of Cultural and morphological characteristics showed a resemblance to Didymella sp. Pathogenicity was confirmed by the detached leaf technique as well as inoculating whole plants in pots. Precise confirmation of the identity of the pathogen was done by sequencing the reference genes using ITS1 and ITS4 markers and sequenced data was subjected to BLAST which showed 99.80 per cent similarity with Didymella rumicicola which was previously only reported in New Zealand on Rumex obtusifolius prior to this study. Host range, as well as bioherbicidal potential of this pathogen on hosts of five different families of cultivated crops along with Rumex plants, revealed that no disease incidence was found on host plant species of other families of cultivated crops, whereas,100% disease incidence and 80% severity were observed on Rumex crispus at 15 and 25 days after inoculation respectively. Physiological studies showed the newly isolated pathogen Didymella rumicicola showed the best radial growth on Potato dextrose agar at pH 6.5 and at a temperature of 25oC.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43468843","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}

The hairy root (HR) cultures system is one of the most useful tools for secondary metabolites (SM) biosynthesis under various growth conditions. In the past, GSLs were mostly used as biopesticides in agriculture, anti-nutritional factors in fodder, and flavors in condiments. However, in recent days, GLSs have received much attention in human health. To investigate the growth response and variation of GSLs accumulation, HRs of mustard were grown in different growth media and auxins. The HRs growth pattern varied largely under the treatments of growth media and auxin. The full-strength SH media responded greatly for achieving the highest dry weight (DW) followed by the ½ SH media and the lowest DW was obtained in full-strength MS media. In all the auxin treatments the HRs production was higher than that of the control. It was noted that at higher NAA and IBA concentrations HR production was increased than that at the lower concentrations. In addition, different growth mediums significantly influenced the GSLs accumulation in mustard HR. The results revealed that ½ B5 media showed the highest total GSLs content followed by B5 and ½ SH. Treatment of mustard HRs with auxins such as IAA and IBA negatively influenced the accumulation of GSLs except for 4-methoxyglucobrassicin. We, therefore, suggest that HRs are a viable option for improving the GSLs content from the HR culture of mustard and that SH and ½ B5 medium provides an alternative approach for mass production of HRs and GSLs in mustard, respectively.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44980304","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}

The paramount aim of the present study was to estimate the heritability, genetic advance and genetic variability of the backcross and selfed population of sweet corn and β-carotene rich inbred combinations viz., USC1-2-3-1× UMI1230β+ and SC1107× UMI1230β+ in order to identify the plants with superior trait combinations. The study involved the recording of fourteen biometrical traits in both the cross combinations which revealed that in backcross and selfed populations, the phenotypic coefficient of variation (PCV) was found to be greater than the genotypic coefficient of variation (GCV) indicating the probable influence of environment in the expression of the traits evaluated. High heritability was recorded for the important trait single plant yield in both the cross combinations of BC2F2 generation. Further, high heritability and high genetic advance as percent of mean was noticed for the traits like plant height, cob length, leaf length and single plant yield under both the cross combinations of BC2F2 generation indicates the governance of additive genes in expression of these traits. Hence, selection for these traits would be effective in developing a genotype with improved yield.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44761088","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}

To date, much research has been considered under investigation, especially for the regeneration of the indigo plant. Here in this study, we investigated the response of sucroses and gelling agents on the shoot organogenesis of the indigo plant. Micropropagation in terms of shoot regeneration and its growth was highly responded to sucrose and gelling agents. While culturing of internode explants on initial shoot regeneration media supplemented with sucrose and gelling agents of phytagar and gelrite significantly upgraded the regeneration efficiency as well as shoot growth. The regeneration capacity of the shoot was augmented with increased levels of sucrose up to 40 g L-1 and then started to decrease, whereas the increasing pattern continued even at the highest concentration (50 g L-1). The highest shoot regeneration (6.0 ± 0.5) was achieved by the treatment of 40 g L-1 giving 7.5 times higher shoot regeneration compared to the control. The increasing pattern for shoot length was more pronounced than that of shoot regeneration. The shoot length ranged from 10.2 mm to 23.5 mm within the sucrose treatments. In this study, the highest shoot length (23.5± 0.21) was observed by the treatment of 50 g L-1 exhibiting 2.3 times higher shoot length compared to the control. Gelling agent gelrite performed better than phytagar for both regeneration and shoot length growth. The shoot regeneration among the phytagar treatments ranged from 3.8 to 6.0 shoots/explant whereas the shoot regeneration ranged from 6.6 to 7.2 among the gelrite treatments. The highest shoots/explant (7.2) and the longest shoot length (22.4 mm) were observed due to the treatment of gelrite 3. The lowest shoot regeneration and shoot length were denoted when phytagar 9 was applied. It is proposed from our study that sucrose and gelling agent especially gelrite 3 could be applied in shoot organogenesis and plant transformation of any plant species, especially for P. tinctorium.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42504839","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}

Fruit peels are the main waste and may contain various biologically active compounds. However, no prior knowledge about the therapeutic compounds of the peel. The objective of the present study was to unveil therapeutic compounds from the peel by Gas Chromatography–Mass Spectrometry (GC-MS) based metabolomics analysis. Metabolites from the kadam fruit peel were isolated and derivatized using MSTFA, characterized by the GC-MS analysis. Raw spectral data were pre-processed, and peak identification was performed using SHIMADZU Postrun analyse software. The metabolites in N. cadamba fruit peel were identified by comparing the peaks with the mass spectral reference database NIST v20. The results showed that the peel of kadam fruit contains 149 metabolites, which were further categorized into 46 different metabolite classes, with 52 different metabolic pathways and 63 biological functions. The principal roles of the metabolites were identified by functional annotation and enrichment analysis. It revealed that metabolites were responsible for anti-inflammation, anti-oxidant, anti-microbial, and anti-cancer properties. In summary, the peel of kadam fruit also contains various therapeutic compounds like other cadamba parts (i.e., roots, leaves, barks, and fruits). Further, comparing the peel with other parts discloses the peel-specific metabolites. The results obtained in this study could be useful for the pharmaceutical industry.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45214162","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}

Negative skewness refers to redundant gene activity, positive skewness is connected to complementary gene action. Positive kurtosis suggests the existence of gene activity controlled by a smaller number of genes. Negative kurtosis shows a lack of gene activity and is controlled by a large number of genes. The BC2F2 population of plant height and single plant yield showed positive skewness and platykurtic distribution, suggesting that the genes were governed by complementary gene action and controlled by the large number of genes. This implied need for rigorous selection to achieve a genetic gain in later generations. Cob length and kernel weight showed a duplicate gene action which implied that mild selection can fix these traits and accelerate genetic gain.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41843431","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}
