Abstract

We have developed an effective plant propagation method of „hausa potato‟ through shoot proliferation in vitro, acclimatization in the greenhouse and transplantation of the plantlet on the individual media container for planting material production. The shoot cultures were initiated from shoots that grew from tuber collected from the field, disinfested using standard method and transferred to MS medium with 1 mg/l of BA for shoot proliferation. The proliferating shoots were then subcultured to MS medium with no growth regulators to induce rooting and enlarge the shoot. The plantlets were acclimatized in a plastic box containing medium of a mixture of cocopeat, sands, rice husk charcoal and top soil covered with plastic film to maintain humidity. The plantlets survived at 85% and almost 100% grew into planting materials ready for transplanting in the soil. The planting materials survived in the field and produced tuber normally.

Abstract

Asparagine synthetase (AS) is one of the enzyme involves in ammonium metabolism in plant, it catalyzes the transfer of the amino group of glutamine to aspartate giving asparagine. Asparagine serves as a major nitrogen transport and storage molecule in many higher plants. This research used legume plant Coronilla rostrata callus culture for primary and secondary metabolism study. On primary metabolism, the culture were used to study the phenomenon of asparagine accumulation. Because of the responsiveness of the culture, we investigated the use of this culture for model system to conduct molecular biology study of the nitrogen metabolism. The aim of this study was to isolate cDNAs enconding asparagine synthetase from C. rostrata because of the asparagine accumulate in this culture. Several PCR based approaches were conducted such as RT-PCR, LM-PCR, and RACE. Using these methods, two AS cDNAs was isolated from C. rostrata AS1 (GenBank no AY081945) which a complete cDNA sequence and AS2 which a partial cDNA sequence. (GenBank no AF488726). These two cDNAs had high homology with the legume AS.

Abstract

Transgenic rice plants harboring resistant gene to yellow stem borer, cry1B gene had been obtained. However, the cry1B gene in second generation of transgenic rice lines still segregating following Mendelian ratio 3:1. For further use in the breeding programs, it is important to ensure that the gene is dominant gene and the plants are homozygous for cry1B gene. Selection of homozygous transgenic rice lines containing cry1B gene at third, fourth and fifth generation had been conducted by PCR. The presence of cry1B gene was determined by showing the PCR product of 1.9 kb. Segregation analysis proved that six transgenic rice lines i.e. 3R7.8.15.1, 3R7.8.15.9, 3R7.8.15.10, 3R7.8.15.15, 3R7.8.15.21, 3R7.8.15.29 are homozygous lines for cry1B gene. Moreover, bioassay studies at vegetative stage on six homozygous transgenic rice lines showed that these transgenic rice lines are potential resistant to yellow stem borer comparing with non-transgenic plants, with the score of 0 (indicated no symptom) for six transgenic lines and score of 9 (more than 60% damaged tillers ) for non-transgenic plants. However, to confirm the efficacy of cry1B gene to yellow stem borer in natural condition, confined field trial in endemic area of yellow stem borer should be conducted.

Abstract

The objective of this study was to select and characterize three yeast isolates originating from soil of Raja Ampat region of Papua, Indonesia for its potential to produce cellulase . Selection and characterization of cellulolytic yeast was carried out by measuring cellulolytic Index (IS)with congo red method and measurement of Carboxy Methyl Cellulase (CMC-ase) activity through determination of reducing sugar with dinitrosalycilic methods. Cellulolytic Index (IS) of the isolates Sporobolomyces poonsookiae Y08RA07, Rhodosporidium paludigenum Y08RA29, and Cryptococcus flavescens Y08RA33 were 1.40, 2.60 and 1.66, respectively. CMC-ase produced optimum at pH 8 at 37ºC by isolate Y08RA07; whereas for Y08RA29 and Y08RA33 were at pH 6, at 28ºC. Paper waste was good substrate for cellulase enzyme production by isolate Y08RA07, while for two other isolates the best substrate was CMC. Isolate Y08RA29 having highest cellulase activities when grown in CMC, while isolates Y08RA07 and Y08RA33 achieved highest enzyme activity when grown in bamboo leaf.

Abstract

A total of 137 strains of Actinomycetes were isolated from 14 soil samples collected in 3 part of Lombok Island, Indonesia using SDS-YE (SY) and Rehydration and Centrifugation (RC) isolation methods and Humic Acid Vitamin (HV) agar as isolation media. All the isolates were identified by morphological characteristic and by analysis of 16S rRNA gene sequence. On the basis of their morphology and 16S rRNA gene sequence, 67% of isolates were belonged to the Streptomyces Group and 33% of isolates were belonged to the Rare-Actinomycetes (Non-Streptomyces) Group. Nine families and 15 genera were found from the samples. It is indicated the richness of actinomycetes in these area. The genus Streptomyces is the most abundant in all soil samples, occupying 67% of all isolates by using SY method; while the genus Actinoplanes is mainly found by using RC as isolation method. Two strains belong to the genus Virgisporangium and Catenulispora that showed taxonomic interest need further study for describing as ne species.
