Service Specifications

Khoom siv:

Feem ntau, tsawg kawg yog peb pawg neeg (xws li subspecies lossis hom kab mob) raug pom zoo.Txhua sub-population yuav tsum tsis pub tsawg tshaj 10 tus neeg (Nroj tsuag > 15, tuaj yeem txo qis rau hom tsawg).

Sequence Strategy:

* WGS tuaj yeem ua haujlwm rau cov tsiaj uas muaj kev siv genome zoo, thaum SLAF-Seq muaj feem xyuam rau hom tsiaj nrog lossis tsis muaj kev siv genome, lossis siv cov genome ntawm cov khoom tsis zoo.

    Resequencing: sequencing qhov tob: 10 ×

    Cov txiaj ntsig tseem ceeb

    Hauv txoj kev tshawb no, 194 Suav cabbages tau ua tiav rau kev rov ua dua nrog qhov nruab nrab qhov tob ntawm 10 ×, uas tau txais 1,208,499 SNPs thiab 416,070 InDels.Phylogenetic tsom xam ntawm 194 kab no qhia tau hais tias cov kab no tuaj yeem muab faib ua peb hom ecotypes, caij nplooj ntoos hlav, caij ntuj sov thiab caij nplooj zeeg.Tsis tas li ntawd, cov qauv pej xeem thiab PCA tsom xam tau qhia tias lub caij nplooj ntoo hlav suav suav tau los ntawm lub caij nplooj zeeg zaub qhwv hauv Shandong, Suav.Cov no tau tom qab qhia rau Kaus Lim Kauslim thiab Nyij Pooj, hla nrog cov kab hauv zos thiab qee qhov lig-bolting ntau yam ntawm lawv tau qhia rov qab mus rau Tuam Tshoj thiab thaum kawg los ua Spring Suav cabbage.

    Genome-wide scanning ntawm lub caij nplooj ntoos hlav Suav cabbages thiab lub caij nplooj zeeg cabbages ntawm kev xaiv tau qhia 23 genomic loci uas tau mus los ntawm kev xaiv muaj zog, ob ntawm cov uas tau sib tshooj nrog bolting-lub sij hawm tswj cheeb tsam raws li QTL-mapping.Ob thaj chaw no tau pom tias muaj cov noob tseem ceeb uas tswj cov paj, BrVIN3.1 thiab BrFLC1.Ob lub noob no tau lees paub ntxiv tias yuav koom nrog hauv lub sijhawm bolting los ntawm kev kawm transcriptome thiab kev sim hloov pauv.
