Crop & Livestock Genomics
Crop & Livestock Genomics Overview
Advanced genomics gives us unprecedented insight into the genetic makeup of crops and livestock. Our work centers on two pivotal areas: exploring genetic diversity and identifying the genes that control important traits.
The process starts by detecting the full range of genetic variants within a population. We then use sophisticated bioinformatics to connect these variants to specific characteristics. This allows us to swiftly decode complex genetic information and accelerate the development of superior agricultural varieties.
Genetic variant exploration refers to the detection of genetic variations within crop and livestock populations. These variations can stem from single - nucleotide polymorphisms (SNPs), copy number variations, structural rearrangements, etc. Such variations naturally exist among different individuals within a population. By integrating bioinformatics with genomic data, we can expedite the discovery of genes that are crucial for enhancing agricultural productivity and quality.
Our Crop & Livestock Genetic Variant Exploration & Trait - Associated Gene ID Service Enhances Your Agricultural Research with:
- Accelerated Trait - Associated Gene Discovery: Leveraging sophisticated machine learning algorithms trained on extensive crop and livestock genomic datasets, we can rapidly screen out potential genes associated with important agricultural traits. This not only shortens the time required for gene discovery but also increases the likelihood of identifying genes with high agricultural value. For example, in crops, we can quickly find genes related to high - yield, disease resistance, or stress tolerance. In livestock, we can identify genes influencing meat tenderness, milk fat content, or fertility.
- Insights into Agricultural Trait Mechanisms: Our approach uncovers novel genetic variants and trait - associated genes that provide deep insights into the underlying mechanisms of complex agricultural traits. This knowledge is vital for developing targeted breeding strategies and improving agricultural production efficiency.
- Research Acceleration Platform: By integrating bioinformatics, machine learning, and genomics, our platform acts as a powerful engine for agricultural research. It enables the rapid discovery of new genes, genetic pathways, and molecular markers for important traits, significantly speeding up the entire research and development cycle.

How We Deliver This Solution
Sample Collection & Preparation
- Diverse Crop/Livestock Population Recruitment
First, we will form diverse groups of plants and animals, including wild relatives, local species and commercial species. By analyzing these samples with a broad genetic background, we can precisely identify genetic variations related to important traits, such as drought tolerance of crops or disease resistance of livestock.
Meanwhile, we consciously include groups from different geographical regions with different phenotypes. This helps us discover genetic markers specific to the population, which can not only support species conservation but also tailor breeding plans for specific environments.
- Multi-Tissue & Multi-Omics Sampling
To establish the association between genetic variations and actual traits, when collecting samples, we cover various tissues (such as leaves, roots, muscles, and blood), and simultaneously record environmental data. We adopt a multi-omics approach, integrating genomic, transcriptomic and metabolomic data to comprehensively map the association between genes and traits.
For instance, when analyzing corn under drought stress, we simultaneously detect the transcriptome data of its root system and soil moisture. Through this kind of correlation analysis, the key genes that respond to drought stress can be accurately identified.
Sequencing
- Whole Genome Resequencing (WGR)
- We apply WGR to conduct comprehensive population scans, detecting SNPs, indels, and structural variants across entire genomes. This approach helps uncover rare variants linked to key traits such as yield or meat quality, and can identify selective sweeps within breeding populations. A major application is discovering adaptive alleles in wild relatives—like cold tolerance genes in wild wheat—for introduction into elite varieties.

- Reduced Representation Sequencing (e.g., GBS, RAD-seq)
Bioinformatics & Functional Analysis
- Population Structure & Admixture Analysis
- Using tools like PCA, STRUCTURE, and ADMIXTURE, we characterize genetic diversity and ancestry to delineate subpopulations, trace gene flow, and determine breed composition. These insights directly support conservation planning—for instance, preserving unique alleles in indigenous livestock—and help guide strategic breeding decisions.
- Tool Example: PLINK for SNP filtering and ADMIXTURE for ancestry inference.
- Selection Signature Detection
- We use statistical methods like XP-CLR and iHS to scan genomes for regions that have undergone positive selection. This helps us uncover alleles with proven historical importance—such as those behind increased milk yield in cattle or heat tolerance in poultry. By highlighting these genomic regions under strong selection pressure, we provide breeders with high-value targets to prioritize in their marker-assisted selection programs.
- Gene-Trait Association (GWAS) & Functional Annotation
- We link variants to phenotypes (e.g., grain size in rice, wool quality in sheep) using mixed linear models to control for population structure. Results are annotated to prioritize candidate genes (e.g., FLOWERING LOCUS C in crops).
- Tool Example: GEMMA for GWAS and SnpEff for variant annotation.
- Polygenic Risk Scoring (PRS) for Breeding
- Aggregates multiple QTLs into a score to predict breeding value for complex traits (e.g., feed efficiency in pigs). Helps prioritize elite sires/dams or identify underperforming individuals early.
- Method: Train PRS models using summary statistics from multi-breed GWAS.
- Pathway & Gene Network Analysis
- We take the significant variants identified through GWAS and map them onto biological pathways—for instance, those involved in crop stress tolerance or livestock disease resistance. This contextual mapping allows us to identify the key genes that regulate these processes. The most promising of these genes then become high-value candidates for precise intervention using advanced gene-editing or targeted breeding strategies.
- Tool Example: We typically use platforms like Metascape or Cytoscape to visualize and interpret these complex gene networks.

Our Advantages
Nutritional Quality Optimization: ML-Assisted Nutrient Gene Screening
Traditional ways of improving nutritional quality mainly focus on post - harvest processing. We use machine-learning models trained on genomic, phenotypic and nutritional datasets to prioritize genes involved in nutrient synthesis and accumulation in crops and livestock. By analyzing genetic variations associated with nutrient levels, such as vitamins, minerals, and proteins, we identify genes that can be targeted for breeding. This helps in developing agricultural products with enhanced nutritional value, meeting the growing demand for healthy and nutritious food in the market.

Applications
Breed Improvement & Selection Programs
Genomic sequencing identifies key trait-associated markers (e.g., yield, disease resistance, meat quality), enabling precision breeding in crops and livestock to accelerate genetic gain and reduce generation intervals.
Conservation of Genetic Diversity
By applying population genomics, we can identify critical threats to genetic health—such as bottlenecks, inbreeding, and the loss of unique alleles—in endangered breeds and wild relatives. These insights directly support the development of effective conservation strategies, helping to protect biodiversity and maintain adaptive potential for the future.
Disease Resistance & Health Management
Genome-wide association studies (GWAS) pinpoint genetic variants linked to pathogen resistance (e.g., PRRS in pigs, rust in wheat), supporting development of resilient varieties and reducing reliance on chemicals.
Parentage & Traceability Verification
High-resolution SNP panels validate animal/plant parentage, ensure breed purity, and enable supply chain traceability—critical for premium markets (e.g., organic, heritage breeds) and intellectual property protection.

Case Study
Long-read sequencing of 111 rice genomes reveals significantly larger pan-genomes.
Journal:Genome Res.
Published:2022
- Incompleteness and inaccuracy of SGS-based pan-genomes: Pan-genomes constructed using second-generation sequencing (SGS) technology, such as Illumina sequencing, suffer from incomplete genome coverage and inaccurate gene prediction due to short read lengths (<200 bp). This limits their ability to fully capture genomic diversity and gene presence-absence variations (PAVs) in crop species like rice.
- Limitations of sample representativeness and population size: Previous pan-genome studies based on SGS data or small/less representative samples have produced results that require improvement and validation. The quality of a pan-genome depends not only on sequencing technology but also on the diversity and size of the population studied.
- Genomic context loss and redundancy: SGS-based pan-genomes often lose genomic contexts and contain redundant sequences, making it difficult to accurately identify novel genes and structural variations.
- Integration of third-generation sequencing (TGS): The study employed long-read sequencing (LRS) technology, such as PacBio or Oxford Nanopore, to construct high-quality rice pan-genomes. Long reads (>10 kb) help resolve repetitive sequences, improve genome assembly continuity, and capture novel sequences that are missed by SGS.
- Novel computational methods for long-read data processing: The researchers introduced a series of new steps to handle long-read data, including:
Unmapped sequence block filtering: Removing low-quality or contaminant sequences.
Redundancy removal: Eliminating duplicate sequences to ensure a non-redundant pan-genome.
Sequence block elongating: Extending short sequences to improve assembly completeness.
- Diverse and representative sampling: The study used 105 Asian cultivated rice (Oryza sativa) accessions representing all major populations, plus six wild rice (Oryza rufipogon) accessions, to ensure broad genetic diversity and population representativeness.
- Construction of a comprehensive rice pan-genome: The TGS-based pan-genome constructed from 105 rice accessions contains 604 Mb of novel sequences compared to the Nipponbare reference genome (NipRG). When six wild rice accessions were included, the total novel sequences expanded to 879 Mb, with 19,000 novel genes identified.
- Validation and expansion of the 3K-RG pan-genome: The study validated and significantly expanded the previous rice pan-genome constructed from 3,010 rice genomes (3K-RG) using SGS. The TGS-based pan-genome is more comprehensive and accurate, particularly in capturing repetitive sequences and novel genes.
- Creation of gapless high-quality reference genomes: High-quality, gapless reference genomes were generated for five major rice populations, providing a foundational resource for future genomics studies.
- Methodological advancement: The developed pan-genome construction pipeline for long-read data can be applied to other crop species, accelerating genomics research and breeding programs. This method addresses key limitations of SGS-based approaches and sets a new standard for pan-genome studies.

FAQ
How much sample size is needed for a robust population genomics study?
Sample size depends on genetic diversity and study objectives. For GWAS or selection scans, 50–200+ individuals per population are typical. For conservation genetics, even small populations (20–50) can reveal inbreeding or unique alleles. We help optimize sampling strategies based on your goals.
Can you analyze non-model species (e.g., indigenous crops/livestock)?
Yes! Our pipelines are adapted for de novo assembly and reference-free analysis, making them ideal for non-model or understudied species. We leverage comparative genomics and low-coverage sequencing to maximize data utility without requiring a reference genome.
