(2006)A research was undergone to study the effect of single and double infection of Cucumber Mosaic Virus (CMV) and Chili Veinal Mottle Virus (ChiVMV) on the growth and yield of five chilli cultivars, i.e. Prabu, Taro, Jatilaba, ... -
Current Research Status of Allelopathy
(2006)The term of allelopathy refers to chemical interactions (inhibitory or stimulatory) between plants, between plants and microorganisms, and between microorganisms. The wealth of information on the processes, procedures, and ... -
Introduction of cryIB-cryIA Hybrid Gene Into Rice (Oryza sativa) Genom cv. Rojolele using Agrobacterium-Mediated Transformation
(2006)Rojolele is one of Indonesian local variety from Javanica group that susceptible to yellow stem borer (Scirpophaga incertulas). Previous study showed that Rojolele can be cultured and regenerated in vitro. Two cry genes, ... -
Detection and Host Range Study of Virus Associated with Pepper Yellow Leaf Curl Disease
(2006)High incidence of Pepper yellow leaf curl virus (PepYLCV) was observed in Indonesia since early 2000. Disease incidence in Yogyakarta, Central and West Java reached 100% on Capsicum frutescens, but only 10-35% on C. annuum. ... -
Matriconditioning Improves Thermotolerance in Pepper Seeds through Increased in 1-Aminocyclopropane-1-Carboxylic Acid Synthesis and Utilization
(2006)Matriconditioning using a solid carrier, Micro-Cel E, was applied on pepper seeds and its effects on the improvement of thermotolerance through the ethylene biosynthesis were studied. Untreated and matriconditioned seeds ... -
Allotopic expression of a gene encoding FLAG Tagged-subunit 8 of yeast mitochondrial ATP synthase
(2006)Subunit 8 of yeast mitochondrial ATP synthase is a polypeptide of 48 amino acids encoded by the mitochondrial ATP8 gene. A nuclear version of subunit 8 gene has been designed to encode FLAG tagged-subunit 8 fused with a ... -
Quantitative Trait Loci (QTL) Analysis for Production Traits of Birth Weight and Weight 360 days in Backcross Sheep
(2006)Four half-sib families (n = 382) consisting predominantly of ITT x Merino x Merino backcross progeny, including some F2 progeny were used to analyze QTL for two production traits (Birth weight = BW1 and Body weight at 360 ... -
Physiological Response of Crocidolomia pavonana to the Calophyllum soulattri Active Fraction
(2006)The objective of this study was to evaluate the physiological response of the cabbage head caterpillar Crocidolomia pavonana treated with an active fraction of Calophyllum soulattri bark extract. Extraction of the test ... -
Vegetative Cell Division and Nuclear Translocation in Three Algae Species of Netrium (Zygnematales; Chlorophyta)
(2006)Three species of Netrium oblongum, N. digitus v. latum, and N. interruptum were studied for their mode in the vegetative cell division and nuclear translocation during mitosis using light and fluorescence microscopy. The ... -
Involvement of a Gene Encoding Putative Acetate Kinase in Magnetosome Synthesis in Magnetospirillum magneticum AMB-1
(2006)A nonmagnetic mutant of Magnetospirillum magneticum AMB-1, designated NMA40, was constructed by mini-Tn5 transposon mutagenesis to identify genes involved in magnetosome synthesis. Transposon delivery was carried out through ... -
Molecular Detection of Endophytic Bacteria on Plantlet Tissues of Sugarcane
(2007)Endophytic bacteria live in plant host tissues without causing any symptoms. The aim of this study was to examine the indigenous endophytic bacteria on sugarcane plantlets produced from the young leaf cells by using tissue ... -
Effetct of Gamma Irradiation on Regeneration Capacity of Mangosteen Nodular Callus
(2007)The research was conducted to determine the effect of gamma irradiation on regeneration capacity of mangosteed nodular callus. Nodular calli derived from a leaf as explants and cultured on MS medium containing combination ... -
Nitrogen Resorption and Nitrogen Use Efficiemcy in Cacao Agroforestry Systems Managed Differently in Central Sulawesi
(2007)Cacao agroforestry is a traditional form of agriculture practiced by the people of Central Sulawesi. These agroforestry systems vary from a simple system following selective cutting of forest trees, to a more sophisticated ... -
Diversity of Pollinator Insect in Relation to Seed Set of Mustard (Brassica rapa L. Cruciferae)
(2007)Pollinators provide key services to both natural and agricultural ecosystems. Agricultural productivity depends, in part, on pollinator populations from adjacent seminatural habitats. Here we analysed the diversity of ... -
