Intensive management of modern agriculture and the extensive use of chemical reagents such as pesticides have led to the gradual reduction of most pollinating insects, such as bees.
these insects pollinate crops, and if they disappear, most of the food will disappear.
oil palm (Elaeis Guineensis) is a perennial single leaf plant, originally highly dependent on artificial pollination and wind media, pollination effect is poor, low yield.
Since the 1980s, Southeast Asian countries have introduced a pollinator from Africa, elaeidobius kamerunicus, to increase productivity, save labour costs, increase yields by 30-40 per cent per plant, and introduce pollinators from other places or serve as a reference for modern agriculture.
as a group, like nasal worms are known for their close correlation with oil palm blossoming, their history as pollinators dating back 13.5 million to 18 million years ago in the Jurassic and Cretaceous periods, is considered to be one of the oldest pollinators, but its special identification and regulation mechanism sandals with oil palm blossoms are not known.
the joint research of the Institute of Microbiology of the Chinese Academy of Sciences, ye Jian, in collaboration with researchers from singapore, Indonesia and the United States, revealed the molecular mechanism of regulating the reaction of oil palm synthesis secondary metabolites to the pollination behavior of elephant nasal worms.
researchers measured the genomes of the commercially-promoted oil palm variety Dura, completed high-quality sequencing of the high-yielding mother-thick-shell Dura genome, genome re-sequencing of multiple seed resources, and evolutionary analysis, and used transcription group analysis and genetically modified technology to study the molecular mechanisms of hybrid advantages of oil palm high-yield oil.
combined with the volatile metabolites of oil palm flowers and the analysis of the phonospheric pollination behavior of the elephant nasal worm, the identification of a phenyl propylene compound only synthesized in oil palm male flowers - methyl pepper phenol, has an effective effect in attracting elephant nasal worms to pollinate behavior. On the basis of the preliminary analysis of the oil palm genome in the early period, the
used transcriptomics and biochemical functional analysis to find a series of genes of methyl pepper phenol synthesis pathway synth system, as well as the switchgene-EgMYB4, which regulates the synthesis of lignin and phenyl-lipid compounds.
increased the ability of the oil-brown gene EgMYB4 to be 15-20 times higher in the synthetic phenyl propylene compounds of the F-and-F plant by expressing it in the Gemini-flavored essential oil (Fragrance and Flavor, F.F.) crop.
the functional analysis of oil palm and pollinator-specific recognition of important compoundmethyl pepper phenol synthesis and regulation pathways, but also for the use of plants as bioreactors to produce high value-added industrial products, providing new ideas and important genetic components.
