Glucosinolates are defense-related secondary metabolites found in Brassicaceae. When Brassicaceae come under attack, glucosinolates hydrolyzed into different forms of glucosinolate hydrolysis products (GHPs). Among the GHPs, isothiocyanates most comprehensively characterized defensive compounds, whereas functional study nitriles, another group GHP, is still limited. Therefore, this investigates whether 3-butenenitrile (3BN), a nitrile, can trigger signaling pathways involved regulation...
Magnaporthe oryzae is a fungal pathogen contributing to rice blast diseases globally via their Avr (avirulence) gene. Although the occurrence of M. has been reported in Sarawak since several decades ago, however, none focused specifically on genes, which confer resistance against associated molecular pattern-triggered immunity (PTI) host. The objective this study isolate genes from 7’ (a isolate) that may contribute susceptibility towards diseases. In study, AvrPiz-t, AVR-Pik, Avr-Pi54, and...
Rphq2 , a minor gene for partial resistance to Puccinia hordei was physically mapped in 188 kbp introgression with suppressed recombination between haplotypes of rphq2 and barley cultivars. Partial non-host resistances rust fungi (Hordeum vulgare) may be based on pathogen-associated molecular pattern (PAMP)-triggered immunity. Understanding help understand resistance, vice versa. We constructed two non-gridded BAC libraries from cultivar Vada line SusPtrit. is immune non-adapted fungi,...
Rice blast disease (causal agent: Pyricularia oryzae) is an important rice worldwide as it can cause significant yield loss. Resistance genes in recognise the corresponding avirulence (Avr-gene) of P. oryzae and suppress attack pathogen proposed 'gene-for-gene' interaction. This interaction highly specific. The resistance will be rapidly breakdown owing to plasticity Avr-gene. breaking down problem managing well sustaining a resistant variety. paper aimed study analyse sequence variation...
Aims: Rice blast disease caused by Pyricularia oryzae is one of the major biotic diseases rice in Sarawak, Malaysian Borneo.This study aims to isolate and characterize fungus obtained from infected leaf collected four different divisions viz, Miri, Serian, Sri Aman, Kuching.Methodology results: Twelve succeeded isolates were pre-identified as P. morphological characteristics spores, followed verification through (internal transcribed spacer) ITS sequencing.The evaluated for characteristics,...
Partial resistance quantitative trait loci (QTLs) Rphq11 and rphq16 against Puccinia hordei isolate 1.2.1 were previously mapped in seedlings of the mapping populations Steptoe/Morex Oregon Wolfe Barleys, respectively. In this study, QTL was performed at adult plant stage for two challenged with same rust isolate. The results suggest that are effective only seedling stage, not stage. cloning several genes responsible partial barley to P. will allow elucidation molecular basis type defence. A...
Aims: Piper nigrum L. (black pepper) is an economically important commodity plant in Malaysia, which generated RM 200.95 million from pepper export the year of 2018.However, increase production restricted by diseases.Fusarium wilt one major diseases P. The objectives for this study were to isolate Fusarium spp.associated with selected farms northwestern region Sarawak and characterize spp.isolated morphologically molecularly.Methodology results: spp.were isolated diseased root samples.The...
Rice blast (causal agent: Pyricularia oryzae) is an important disease of rice in Sarawak. Understanding the pathogen’s morphological characteristics, genetic diversity and pathogenicity important. Having a suitable medium for culturing maintaining P. oryzae to ensure availability inoculum or materials under laboratory conditions. Oatmeal agar (OMA) potato dextrose (PDA) are common media used growing oryzae. OMA allows better mycelial growth sporulation as compared PDA. There also other...
Malaysia rice production is threatened by blast disease, caused Pyricularia oryzae. Yield can be greatly reduced this disease as it attack all the aerial parts of including leaves, node, neck, and collar. The use resistant cultivar, which produced from resistance breeding, control effectively. Sarawak, in Malaysian Borneo, has diverse landraces, genetic resources for breeding. Study on Sarawak landraces against P. oryzae, still limited. In study, diseased leaf samples were collected fields...
Phytophthora foot rot disease remains a deadly of black pepper in Sarawak, major producing state Malaysia. This study characterised three isolates, recovered from diseased plant tissues infected vines two farms Julau district, Sarawak. The isolates were confirmed to be capsici based on the distinct torulose hyphae characteristic and molecular analysis. exhibited various colony sporangia morphologies growth rates. Two mating types detected among formation oogonia pairing tests between - one...
In recent years, there has been a growing trend in the popularity of natural fiber-reinforced polymer composites (NFRPC). Numerous researchers have put forward various alternatives to synthetic fibers. Luffa is one many fibers can be integrated into NFRPCs. with its unique interconnecting branch (mat/mesh) suitable for this study, luffa reinforced high-density polyethylene (Luffa/HDPE) composite was fabricated using compression molding machine. preparation fiber, were cylindrically cut-out...
The fish health status and parasitic infection in paddy fields are understudied Borneo. This study was done to compare the prevalence abundance of parasites on freshwater fishes upstream downstream rivers fields. Parasite by collecting live samples using ten minnow traps with baits at each site Serian Padawan, Sarawak, from October 2017 until March 2018. A total 120 were examined during this period. Cold anaesthesia applied prior ectoparasite endoparasite microscopic screening, which...
Usage of synthetic fungicides has inevitably been one the agricultural practices in combating crop pathogens and maintaining quality production. Although have proven to be profoundly effective, excessive frequent reliance on these caused negative impacts environment human health. Besides that, indiscriminate use may lead development resistant strains pathogenic fungi. The need find an alternative solution led interest finding plant-based fungicides. This study aimed test antifungal...
