International Journal of Bioassays , 2013,
Abstract: The rhizosphere mycoflora of two varieties of sugarcane (Saccharum officinarum L.) was studied qualitatively and quantitatively from sugarcane plantation in Baramati tehsil. Two sugarcane varieties viz. CO 86032 and CO 0265 were investigated. With age activities of fungi increased. When near maturity the number of colonies declined. Isolated fungi from both rhizosphere and non rhizosphere soil were dominated by Aspergillus, Alternaria, and Rhizopus. Fungi including Fusarium spp., and dark sterile mycelia were present in higher frequencies on root surfaces than in the surrounding soils. Although the results were slightly varying the number and the type of fungal colonies in both the varieties were nearly same.

Abstract: Experiments were carried out in order to micropropagate sugarcane cultivars through shoot tip and auxilliary bud culture. Rinsing of four cultivars of sugarcane, namely CP-48-103, CP-57-614, CP-69-1062, and NCO-310 in 75% alcohol for 60 seconds and their subsequent disinfection with sodium and calcium hypochloride (1.5% active material) for 15 minutes decreased a significant amount of infection of explants in the medium. The use of the Murashing and Skoog (MS) solid and liquid medium with 1 mg/l Indole Butyric Acid (IBA), 1 mg/l Kinetin, 100 mg/l mio-inositol, 1 mg/l Thiamin HCl, and 2% sucrose had significant superiority (P<0.05) to 1/2 MS solid medium. Also, to increase the multiplication in a sterile medium (In vitro), two kinds of solid and liquid MS medium, with a hormone combination of 1 mg/l IBA, 2 mg/l Kinetin and 1 mg/l 6-(benzylamino)-9-(2-tetrahydropyranyl)-9H-purine (BAP) were applied which yielded the highest amount of proliferation. The plants formed roots in Schenk and Hildebrandt (SH) medium with a hormone combination of 5 mg/l IBA and 1 mg/l Kinetin. When activate charcoal was used in the medium, a higher percentage of the plants became rooted and a larger number of adventitious roots were produced than in the dark-light or light treatments.

Plant Pathology Journal , 2003,
Abstract: Among two different Saccharum species viz; Saccharum officinarum (varieties/ lines Isd 16, Isd 20, Isd 24, Isd 28, BC4 and Saccharum spontaneum (line S 20) were screened against red rot (Colleotrichum falcatum) disease resistance by artificial inoculation following standard plug method. The varieties /lines were graded as various levels of susceptibility and resistance using a standard disease index. Among the varieties/ lines tested Isd 20 and BC4 have shown completely resistant, variety Isd 24, S20 have shown moderately, Isd 16 susceptible and Isd 28 highly susceptible. These varieties/ lines (Isd 20 and BC4) may be utilized as one of the sources of resistance on the breeding programme of sugarcane to red rot disease.

Journal of Plant Breeding and Genetics , 2013,
Abstract: The experiment was carried out in the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad to examine the genetic variability and contribution of some morphological characters for cane yield and sucrose %age. Eleven varieties of sugarcane (Saccharum officinarum L.) were evaluated for correlation, metroglyph analysis and divergence analysis. Data on various economic important traits like plant height, cane height, number of tillers /plant, number of leaves/plant, leaf area, cane diameter, cane weight, dry matter contents, juice contents, sucrose value and brix value was recorded. The results pertaining to analysis of variance elucidated highly significant differences among the accessions for all the traits except number of leaves/plant and considerable range of variability. Correlations among various traits were computed and found that association of brix value with cane diameter, leaf area, dry matter contents and sucrose value was positive and significant at genotypic level and positive but highly significant at phenotypic level. Correlation of brix value with number of leaves, cane weight and beggas weight was positive but significant at genotypic and non- significant at phenotypic level. Metroglyph analysis showed that eight clusters had been made with different index scores. Divergence analysis showed that genetic dissimilarity was highest between No.46 and SPF-232 and was lowest among SPSG-26 and COJ-84. Brix value had the highest contribution to genetic divergence followed by cane height and cane weight due to genetic dissimilarity among the genotypes for these traits. The cane diameter and sucrose value had no contribution to the total genetic divergence due to genetic similarity among the genotypes.

Abstract: In a search of the sugarcane expressed sequence tag (SUCEST) database we located three full-length cDNAs (SCCCLR1022D05.g, SCCCRZ1001D02.g and SCBFLR1026E02.g) encoding the 14-3-3 proteins from sugarcane (Saccharum officinarum). The encoded proteins were identified based on the clustering of the expressed sequence tags and were shown to encode proteins similar to 14-3-3 proteins of other monocotyledonous plants. Cluster SCCCLR1022D05.g was 99% similar to the maize 14-3-3-like protein (gi|1345587) while cluster SCCCRZ1001D02.g shared 96% and SCBFLR1026E02.g 94% similarity with the 14-3-3 protein of rice (gi|7435022). Although 14-3-3 proteins have been reported to be specific to particular species, tissue or organ from which they were isolated, all three sugarcane clusters were found to be expressed in several tissues.

Nasiru, I.,Ifenkwe, OP.
Tropicultura , 2004,
Abstract: Six newly developed clones of sugarcane (Saccharum officinarum L.) clones obtained from gamma irradiated progenies (KRS/96/007, KRS/96/002, KRS/96/001) and from bi-parental crosses (SRS/96/305, SRS/96/210 and SRS/96/004) were used in the study of their level of smut disease resistance. The results of the application of the standard smut disease scale of sugarcane showed that all the clones from bi-parental crosses and only one clone (KRS/96/002) from gamma irradiated progenies were highly resistant to smut disease of sugarcane with zero incidence of the disease. Diseased plants were observed on the remaining two clones from gamma irradiated progenies (KRS/96/007 and KRS/96/001), but the percentage of infection was very low (1.1%) and they were therefore also rated as resistant clones.

Journal of Molecular Genetics , 2013, DOI: 10.3923/jmolgene.2013.1.2
Abstract: This study focused on isolation, cloning of TAL from sugarcane. Transaldolase is one of the enzymes of the Pentose Phosphate Pathway (PPP). Transaldolase in non-oxidative phase of OPPP transfer a three carbon dihydroxyacetone moiety from sedoheptulose-7-phosphate and glyceraldehyde-3-phophate to produce Erythrose-4-Phophate (E4P) and fructose-6-phophate. E4P is the precursor for many secondary metabolic pathways including aromatic amino acids, lignin and flavonoid synthesis. Earlier studies revealed that OPPP is incomplete in the cytosol of plants as no genes encoding for a cytosolic TAL. Moreover, there is no study about the TAL genes from sugarcane until to date. Thus, the objective of this study is to isolate TAL gene from sugarcane, to compare its similarity with other plants, to determine its subcellular localization. A total of 1601 bp of TAL has been isolated by PCR. Similarity, studies by ClustalW revealed that TAL show highest similarity (75%) with Zea mays. Analysis of subcellular localization by using Target 1.1 revealed that of TAL from sugarcane was not located in the plastidic.

Abstract: A investigation was undertaken to assess the interrelationship of cane yield and its traits in sugarcane at National Sugar Crops Research Institute, farm Thatta, during 2000-2001. It was observed that cane girth, number of internodes per plant, cane height and millable canes m-2 were positively and highly significantly correlated with cane yield, the regression coefficients for these traits on cane yield were also positive. Multiple correlation and partial regression analysis indicated that cane girth, number of internodes per plant, cane height and millable canes m-2 should be considered in selecting high yielding strains.
