However, citrus anthracnose caused by <em>Colletotrichum</em> spp. constantly becomes a limiting factor in citrus production. Nevertheless, there is no report on molecular basis about the species associates to the citrus anthracnose in Indonesia up to date. Therefore, this research aims to identify the isolates of Colletotrichum spp. based on polyphasic approach which combining morphological character, pathogenicity and multigene analysis using actin, β-tubulin, and GAPDH primers. Twenty-two isolates were obtained from leaves and citrus fruits with anthracnose symptoms which showed various morphological characteristics, both macroscopic and microscopic. Pathogenicity test results showed that all 22 isolates were virulent to Keprok Batu 55 orange and California lemon. The anthracnose symptoms produced are identical to the symptoms in the field, however the symptoms on the California lemon were milder than on the Keprok Batu 55 mandarin. The results of multigene analysis showed that there were three species causing citrus anthracnose in Indonesia, which were <em>C. endophytichum</em>, <em>C. queenslandicum</em>, and <em>C. gloeosporioides</em>. Those three species are <em>C. gloeosporioides</em> species complex, and this is the first report of <em>C. endophytichum</em>, <em>C. queenslandicum</em> causing citrus anthracnose in Indonesia which needs further concern for biosecurity. All isolate sequences based on actin, β-tubulin, and GAPDH gene markers were submitted into the GenBank and got accession numbers of OR188855–OR188875.</p></div>","PeriodicalId":17560,"journal":{"name":"Journal of the Saudi Society of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1658077X24000249/pdfft?md5=8ab93a01c67ba2d0e847e04ce4b216eb&pid=1-s2.0-S1658077X24000249-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140407003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study delved into harnessing the biocontrol potential of Indigenous bacterial isolate by investigating and evaluating its bioactive compounds of ethyl acetate extract with the capacity to suppress <em>G. boninense</em> growth in oil palm plants. Molecular identification was utilized to identify of bacterial isolate using 16S rRNA primers (5′- AGA GTT TGA TCC TGG CTC AG– 3′) and (5′- GGA TAC CTT GTT ACG ACT T– 3′). The agar well diffusion technique and scanning electron microscopy (SEM) were utilized to assess the inhibitory effects of bacterial ethyl acetate extract against <em>G. boninense</em>. A comprehensive analysis of the bacterial ethyl acetate extracts was conducted by gas chromatography - mass spectrometry (GC–MS). Molecular identification confirmed that the bacterial isolate was <em>Bacterium</em> strain BS1727. By employing SEM, the ethyl acetate extracts had influenced on <em>G. boninense</em> mycelial architecture. The exposure to the bacterial ethyl acetate extracts induced degradation and morphological distortion of the mycelial structure, serving as an indicator of its impact on the mycelium's structural modulation.

Pre-treatment of the seeds with cold stratification for 60 days or application of gibberellic acid (GA<sub>3</sub>: 2000 mgl<sup>−1</sup>) effectively broke seed dormancy. Seeds stored at 5 °C (in moist sand) exhibited a minimum viability of 40 %, but all seeds stored dry at room temperatures and moist at 25 °C died. This study on seed germination would be helpful for mass multiplication of the species for reintroduction programmes including <em>ex situ</em> conservation that would aid in improving the subsistence economy of the local indigenous communities.</p></div>","PeriodicalId":17560,"journal":{"name":"Journal of the Saudi Society of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1658077X23001054/pdfft?md5=de9188575d0140bf96e4d270299db0d6&pid=1-s2.0-S1658077X23001054-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135965476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
