Developing functional markers for vitamin E biosynthesis in oil palm.

Vitamin E is essential for human health and plays positive roles in anti-oxidation. Previously, we detected large variation in vitamin E content among 161 oil palm accessions. In this study, twenty oil palm accessions with distinct variation in vitamin E contents (171.

High-quality reference genome sequences of two coconut cultivars provide insights into evolution of monocot chromosomes and differentiation of fiber content and plant height.

Background: Coconut is an important tropical oil and fruit crop whose evolutionary position renders it a fantastic species for the investigation of the evolution of monocot chromosomes and the subsequent differentiation of ancient plants.

Results: Here, we report the assembly and annotation of reference-grade genomes of Cn. tall and Cn.

Coconut genome assembly enables evolutionary analysis of palms and highlights signaling pathways involved in salt tolerance.

Coconut (Cocos nucifera) is the emblematic palm of tropical coastal areas all around the globe. It provides vital resources to millions of farmers. In an effort to better understand its evolutionary history and to develop genomic tools for its improvement, a sequence draft was recently released.

Genome-wide discovery and characterization of long noncoding RNAs in African oil palm ( Jacq.).

Long noncoding RNAs (lncRNAs) are an important class of genes and play important roles in a range of biological processes. However, few reports have described the identification of lncRNAs in oil palm. In this study, we applied strand specific RNA-seq with rRNA removal to identify 1,363 lncRNAs from the equally mixed tissues of oil palm spear leaf and six different developmental stages of mesocarp (8-24 weeks).

Alternative splicing of flowering time gene FT is associated with halving of time to flowering in coconut.

Coconut palm has two distinct types-"tall" and "dwarf"-which differ morphologically. Tall coconut varieties need 8-10 years to start flowering, while dwarf coconut varieties only require 3-5 years. We compared seedling and reproductive stage transcriptomes for both coconut types to determine potential molecular mechanisms underlying control of flowering time in coconut.

iTRAQ-based comparative proteomic analysis of two coconut varieties reveals aromatic coconut cold-sensitive in response to low temperature.

Coconut (Cocos nucifera L.) is an important economic fruit and oil crop largely cultivated in humid and sub-humid tropical coastal zones worldwide. To date proteomic profile analysis of coconut under cold stress yet not been conducted.

Identifying Vitamin E Biosynthesis Genes in by Genome-Wide Association Study.

is a tropical oil crop and has the highest oil yield per unit area. Palm oil has high palmitic acid content and is also rich in vitamins, including vitamin E. We conducted genome-wide association studies in a diversity panel of 161 accessions to identify single-nucleotide polymorphisms (SNPs) linked with vitamin E and validated candidate genes in these marker-associated intervals.

Correlation analysis of cold-related gene expression with physiological and biochemical indicators under cold stress in oil palm.

Oil palm (Elaeis guineensis Jacq.) is a representative tropical oil crop that is sensitive to low temperature. Oil palm can experience cold damage when exposed to low temperatures for a long period.

Genetic control of fatty acid composition in coconut (Cocos nucifera), African oil palm (Elaeis guineensis), and date palm (Phoenix dactylifera).

Predominant gene isoforms and expression bias in lipid metabolism pathways are highly conserved between oil-producing Arecaceae crop species coconut and oil palm, but diverge in non-oil-producing species date palm. Coconut (Cocos nucifera), African oil palm (Elaeis guineensis) and date palm (Phoenix dactylifera) are three major crop species in the Arecaceae family for which genome sequences have recently become available. Coconut and African oil palm both store oil in their endosperms, while date palm fruits contain very little oil.

The genome draft of coconut (Cocos nucifera).

Coconut palm (Cocos nucifera,2n = 32), a member of genus Cocos and family Arecaceae (Palmaceae), is an important tropical fruit and oil crop. Currently, coconut palm is cultivated in 93 countries, including Central and South America, East and West Africa, Southeast Asia and the Pacific Islands, with a total growth area of more than 12 million hectares [1]. Coconut palm is generally classified into 2 main categories: "Tall" (flowering 8-10 years after planting) and "Dwarf" (flowering 4-6 years after planting), based on morphological characteristics and breeding habits.

Genome-Wide Identification and Transferability of Microsatellite Markers between Palmae Species.

The Palmae family contains 202 genera and approximately 2800 species. Except for and , almost no genetic and genomic information is available for Palmae species. Therefore, this is an obstacle to the conservation and genetic assessment of Palmae species, especially those that are currently endangered.

RNA-Seq analysis of Cocos nucifera: transcriptome sequencing and de novo assembly for subsequent functional genomics approaches.

Background: Cocos nucifera (coconut), a member of the Arecaceae family, is an economically important woody palm grown in tropical regions. Despite its agronomic importance, previous germplasm assessment studies have relied solely on morphological and agronomical traits. Molecular biology techniques have been scarcely used in assessment of genetic resources and for improvement of important agronomic and quality traits in Cocos nucifera, mostly due to the absence of available sequence information.

[Generation of selectable marker-free and vector backbone sequence-free Xa21 transgenic rice].

The dominant gene Xa21 with broad-spectrum and high resistance to Xanthomonas oryzae pv. oryzae (Xoo) was transferred into C418, an important restorer line of japonica hybrid rice in China using double right-border (DRB) T-DNA binary vector through Agrobacterium-mediated transformation. 17 transgenic lines were Xa21-positive with high resistance to the race P6 of Xoo through PCR analysis and resistance identification, among the total 27 independent primary transformants (T0) obtained.
