Abstract

AbstractDual inoculation effects of rhizobacteria andAMF as well as the addition of chemical fertilizerson photosynthesis were studied by analyzingprocess of CO2 gas exchange, chlorophyll content,nutrient uptake, sugar content and growth of sweetsorghum. AMF inoculation as a single cultureincreased carbon assimilation, stomatal conductance,intercellular CO2 concentration, phosphoruscontent, chlorophyll content, sugar content, plantheight, shoot weight and mycorrhizal colonization.Interaction of AMF and rhizobacteria increasedsugar content of sweet sorghum stems andpotassium content of sweet sorghum leaves,whereas its interaction with chemical fertilizerssignificantly increased chlorophyll content, sugarcontent and mycorrhizal colonization of sorghumplant roots. Interaction of AMF, rhizobacteria andchemical fertilizers increased sugar content, rootweight and mycorrhizal colonization. The use ofAMF solely or its interaction with rhizobacteriaand chemical fertilizers had a great potential inimproving photosynthesis process of sweetsorghum. The process is associated with increasingcrop productivity, such as sugar content ofsorghum which is potential as a source ofrenewable energy.AbstrakPengaruh inokulasi ganda rizobakteri danFMA dengan penambahan pupuk kimia dipelajaridengan cara menganalisis proses pertukaran gas CO2, kandungan klorofil, kandungan hara dan gula,pertumbuhan dan produktivitas sorgum manis.Inokulasi FMA sebagai kultur tunggal dapatmeningkatkan asimilasi karbon, konduktansistomata, konsentrasi CO2 interselular, kandunganfosfor, kandungan klorofil, kandungan gula, tinggitanaman, berat batang dan derajat kolonisasimikoriza.

Abstract

AbstractSoil aggregation is a dynamic and very important factor for the development of agricultural soil functions. Unstable soil aggregation in a sandy soil type is a limiting factor for plant growth. The aim of this study was to investigate theinfluence of a exopolysaccharide-producing bacterium and organic material on some physical properties of a sandy soil. A highly potential bacterium for exopolysaccharides production, i.e Burkholderia cenocepacia, was isolated froma sandy soil located at Kotawaringin Barat, Central Kalimantan. The isolated bacterium is capable on improving aggregate’s stability of a soil with about 60% sand fraction [medium sand fraction (MSF)]. Interaction between available water and electric conductivity with aggregate stability index has significant correlation in medium sand fraction inoculated by 109 CFU of B. cenocepacia suspension, i.e. r = 0.806* and r=0.966**, respectively. Organic materials and its combination with the addition of 108 CFU B. cenocepacia suspension treatments could increase the aggregate stability index but have no effects on bulk density and total pore space values in an artificial condition of medium sand fraction. AbstrakAgregasi tanah bersifat dinamis dan merupakan faktor penting untuk pengembangan fungsi tanah pertanian. Ketidakstabilan agregat tanah pada jenis tanah berpasir merupakan faktor pembatas untuk pertumbuhan tanaman.Penelitian ini bertujuan untuk mengetahui pengaruh eksopolisakarida bakteri dan bahan organik terhadap beberapa sifat fisik bahan tanah berpasir. Satu bakteri potensial penghasil eksopolisakarida yaitu Burkholderia cenocepacia telah berhasil diisolasi dari bahan tanah berpasir asal Kotawaringin Barat, Kalimantan Tengah. Bakteri ini dapat meningkatkan kemantapan agregat bahan tanah dengan kandungan fraksi pasir sekitar 60% [fraksi pasir sedang (FPS)]. Hubungan antara air tersedia dan konduktivitas elektrik terhadap indeks kemantapan agregat sangat nyata pada bahan tanah FPS yang diinokulasi dengan 109 CFU suspensi B. cenocepacia masing-masing r = 0,806* dan = 0,966**. Perlakuan bahan organik dan kombinasinya dengan penambahan 109CFU suspensi B. cenocepacia dapat meningkatkan indeks kemantapan agregat tetapi tidak mempengaruhi nilai kerapatan lindak dan total ruang pori di dalam fraksi pasir sedang.

Abstract

Summary Pod rot is one of the most important diseases in cacao. This disease could be incited by Phytophthora palmivora, P. megakarya,  P. capsici or P. citrophthora.  The causal agent of pod rot disease in cacao in Indonesia is known to be P. palmivora.  The success of pod rot disease management is partly depend on the success of efforts in reducing the quantity and quality of the disease inoculum above and below soil surface.  Provision of molecular-based detection system would improve the accuracy of determination of these two parameters. The objective of this experiment was to develop a pair of primers that could be used to specifically amplify rDNA fragments of P. palmivora associated with pod rot disease in cacao.  Design of these primers was made based on the DNA sequence of rDNA fragment amplified using a pair of universal primers ITS4/ITS5. Regions showing high degree of dissimilarity among species of Phytophthora and high degree of similarity within the same species of P. palmivora were determined through DNA alignment.  Specific forward primer (DTF) 5¢-CTT AGT TGG GGG TCT CTT TC-3¢  and reverse primer (Ilyas1R) 5¢-GTT CAC CAA TCA TAC CAC C-3¢ were obtained. This pair of primers had been proven to specifically amplify only rDNA fragment, approximately 650 bp, of P. palmivora associated with pod rot disease and stem canker in cacao.Ringkasan Penyakit busuk buah merupakan salah satu penyakit terpenting pada tanaman kakao.  Penyakit ini dapat disebabkan oleh Phytoph-thora palmivora, P. megakarya, P. capsici atau P. citrophthora. Di Indonesia busuk buah disebabkan oleh P. palmivora. Keberhasilan pengendalian penyakit busuk buah salah satunya tergantung kepada keberhasilan penekanan kuantitas dan kualitas inokulum baik yang berada di atas maupun di bawah permukaan tanah. Tersedianya perangkat deteksi molekuler akan sangat membantu dalam upaya penetapan kedua parameter ter-sebut. Penelitian ini bertujuan untuk mengem-bangkan satu pasang primer yang secara spesifik mampu mengamplifikasi hanya fragmen rDNA P. palmivora yang berkaitan dengan busuk buah kakao. Desain primer dilakukan dengan mengacu kepada sekuen rDNA yang diamplifikasi dengan pasangan primer universal ITS4/ITS5. Daerah yang menunjukkan urutan basa dengan tingkat keragaman yang tinggi antar spesies Phytoph-thora dan yang menunjukkan tingkat kesamaan tinggi dalam satu spesies P. palmivora  yang sama  ditelusuri melalui penjajaran DNA. Hasil desain primer diperoleh primer forward (DTF) 5¢-CTT AGT TGG GGG TCT CTT TC-3¢  dan  reverse (Ilyas1R) 5¢-GTT CAC CAA TCA TAC CAC C-3¢. Pasangan primer DTF dan Ilyas1R ini hanya mampu mengamplifikasi fragmen rDNA berukuran 650 bp dari P. palmivora penyebab penyakit  buah  dan kanker batang kakao.

Abstract

Sugarcane (Saccharum sp.) is a vital commodity for global sugar production and biomass generation, with sucrose being the primary sugar accumulated predominantly in the stem. The sucrose transporter protein is essential in facilitating sucrose transport across cells and over long distances within plants, from source to sink tissues. This study focused on the cloning and expression analysis of the SoSUT4 gene in the Bululawang sugarcane variety. A partial coding sequence of SoSUT4, comprising 802 nucleotides and encoding a 267-amino acid protein, was successfully cloned and sequenced. Sequence analysis revealed that the SoSUT4 protein shares high similarity with other SUT4 proteins in monocotyledonous plants, particularly with Saccharum spontaneum and Saccharum hybrid. Bioinformatics predictions indicated that the SoSUT4 protein is localized to the plasma membrane and contains six transmembrane helices. Gene expression analysis further demonstrated that SoSUT4 expression was significantly higher in the middle internodes of the stem compared to the youngest midsection of the leaves. This expression pattern correlates with higher sucrose accumulation in the stem, as reflected by elevated Brix levels in the stem (19.61%) compared to the leaves (19.48%). This finding suggests that SoSUT4 is essential for sucrose translocation to the stem, which serves as the primary storage site for sugar. The study provides valuable insights into the SoSUT gene family in sugarcane, particularly highlighting the role of SoSUT4 in sugar transport and accumulation. Future research should further investigate the underlying mechanisms of SoSUT4 and related genes to enhance our understanding of their impact on sugarcane yield, with potential applications for genetic engineering aimed at improving crop productivity.
