In Malaysia, rice mutant varieties that are genetically altered to confer resistance against blast disease have been substantially developed through mutational breeding program. However, due the limited accessible information on lines, gene variants corresponding and other useful agronomic traits yet be exploited. Here, we conducted whole genome re-sequencing of with kernel elongation in line, Mahsuri Mutant (87,639,446 bp raw reads), its parental (85,156,783 reads) using Illumina Novaseq...

Bacteria isolated from semi-solid waste, SS2B1 exhibited a greater zone of clearance, 9mm with higher lipase activity. isolate demonstrated Gram-positive and rod shape arrangement under microscope observation belong to Bacillus sp based on biochemical characteristics. The effect carbon source, nitrogen medium pH temperature for the production was studied. maximum (0.1228 µg/ml/min) at pH7, 37 0 C by producing bacteria SS2B1, sp. Increased enzymatic obtained when organisms were cultured in...

Tropical fruits contain high vitamins and minerals. Fruits are susceptible towards many pathogenic microorganisms that results unpleasant odours cause foodborne disease. This study was undertaken to isolate identify fungi associated with spoilt commonly sold in Kuala Pilah market, Negeri Sembilan, Malaysia. The presence of fungal organisms examined 3 which include banana (Musa paradisiaca), mango (Mangifera indica) pineapple (Ananas comosus). Mango demonstrated the highest frequency fungus...

Bacterial leaf blight (BLB) is one of major threats in rice production as it can cause 100% yield loss. Concern on the environment and human health has led an attempt to replace existing methods chemical control avoid extensive use bactericides by using endophytic bacteria. The present study was conducted screen characterize bacteria isolated from different sources that potential antagonistic against Xanthomonas oryzaepv. oryzae (Xoo), causal agent bacterial paddy. Two hundred thirty-three...

Labisia pumila or locally known as ‘Kacip Fatimah’ is an herbaceous plant commonly used for dysentery, flatulence, dysmenorrhoea and gonorrhoea. A study was undertaken to investigate the effect of different growth regulators at various concentrations on adventitious root induction from leaf explants pumila. Murashige Skoog (MS) medium supplemented with auxins; indole-acetic acid (IAA), indole-butyric (IBA) naphtaleneacetic (NAA) each 0, 1, 3, 5, 7 mg/L were evaluated their effects induction....

Magnophorthe oryzae is one of the most destructive disease that affected rice productivity.Developing new breeding strategies for durable blast resistant varieties essential crop protection.In this study, we aimed to introgress a resistance gene using local genotypes, Pongsu Seribu 2 into MR264, high-yielding variety susceptible thru Marker-Assisted Backcrossing (MABC) approach.Results demonstrated that, (Pi-kh) was successfully incorporated MR264-rice variety.Two foreground markers, RM206...

Rice (Oryza sativa L.) blast disease is one of the most destructive rice diseases in world. The fungal pathogen, Magnaporthe oryzae, causal agent disease. Development resistant cultivars preferred method to achieve sustainable production. However, effectiveness hindered by genetic plasticity pathogen genome. Therefore, information on resistance and virulence stability are vital increase our understanding molecular basis resistance. present study set out elucidate pattern identify potential...
