The genome sequence of the African oil palm, main source production, is used to predict at least 34,802 genes, including biosynthesis genes; comparison with draft South American palm reveals that two species may have diverged in New World and segmental duplications chromosome arms define palaeotetraploid origin trees. Two papers published this issue Nature deal genetics variants one most important crops use today — Elaeis guineensis its cousin oleifera. Palm accounts for almost half edible...

Oil palm is the second largest source of edible oil which contributes to approximately 20% world's production oils and fats. In order understand molecular biology involved in vitro propagation, flowering, efficient utilization nitrogen sources root diseases, we have initiated an expressed sequence tag (EST) analysis on palm.In this study, six cDNA libraries from zygotic embryos, suspension cells, shoot apical meristems, young flowers, mature flowers roots, were constructed. We generated a...

Background The somatic embryogenesis tissue culture process has been utilized to propagate high yielding oil palm. Due the low callogenesis and rates, molecular studies were initiated identify genes regulating process, their expression levels are usually quantified using reverse transcription quantitative real-time PCR (RT-qPCR). With recent release of palm genome sequences, it is crucial establish a proper strategy for gene analysis RT-qPCR. Selection most suitable reference should be...

Abstract Increased frequency and severity of flooding are linked to global warming. Flooding stress can severely affect crop yields plant survival, therefore the livelihoods farmers. An oil palm breeding trial plot consisting six progenies in Terengganu, Malaysia, happened be inundated with within a year after planting annually for 2 years thereafter. recurred at 8th several times that 14‐year period monitoring. Due uneven terrain this trial, palms were exposed various flood levels...

A boost of 20-30 per cent in yield is expected from tissue culture-derived planting materials. Troubled by a shrinking land resource, cloning good performing palms well-received sustainable alternative. Cloning elite oil entrenched breeding programmes as way to outpace the long cycle palm which generally results slow introduction new improved materials into commercial pool. However, emergence somaclonal variant known mantled phenotype, drastically reduced yield, caused industry relook at...

The mantled abnormality phenotype of the oil palm affects fruit development and thus jeopardizes yield. Cytokinins have been implicated in phenotype. Endogenous cytokinin levels normal phenotypes were compared to determine whether specific cytokinins are associated with mantling. identified quantified vitro cultures inflorescences from palms. Twenty-two isoprenoid cytokinins, comprising zeatin, dihydrozeatin, isopentenyladenine types, quantified. Total levels, particularly trans-zeatin...
