The haplotype-resolved genome assembly of an ancient citrus variety provides insights into the domestication history and fruit trait formation of loose-skin mandarins

Genome biology, Journal Year: 2025, Volume and Issue: 26(1)

Published: March 17, 2025

Loose-skin mandarins (LSMs) are among the oldest domesticated horticultural crops, yet their domestication history and genetic basis underlying formation of key selected traits remain unclear. We provide a chromosome-scale haplotype-resolved assembly for ancient Chinese citrus variety Nanfengmiju tangerine. Through integration 77 resequenced 114 published germplasm genomes, we categorize LSMs into 12 distinct groups based on population genomic analyses. infer that ancestors modern cultivated diverged from wild in Daoxian approximately 500,000 years ago, when they entered Yangtze Pearl River Basins. There, were four cultivation groups, forming cornerstone LSM cultivation. identify selective sweeps quantitative trait loci genes related to important fruit quality traits, including sweetness size. reveal co-selection sugar transporter metabolism associated with increased sweetness. Significant alterations auxin gibberellin signaling networks may contribute enlargement fruits. also comprehensive, high-spatiotemporal-resolution atlas allelic gene expression during development. detect 5890 allele pairs showing specific patterns significant increase variation levels. Our study provides valuable resources further revises origin LSMs, offering insights improvement plants.

Genomic prediction and genome-wide association study using combined genotypic data from different genotyping systems: application to apple fruit quality traits

Horticulture Research, Journal Year: 2024, Volume and Issue: 11(7)

Published: July 1, 2024

Abstract With advances in next-generation sequencing technologies, various marker genotyping systems have been developed for genomics-based approaches such as genomic selection (GS) and genome-wide association study (GWAS). As new platforms are developed, data from different must be combined. However, the potential use of combined GS GWAS has not yet clarified. In this study, accuracy prediction (GP) detection power increased most fruit quality traits apples when using systems, Illumina Infinium single-nucleotide polymorphism array by random amplicon sequencing-direct (GRAS-Di) systems. addition, GP model, which considered inbreeding effect, further improved seven traits. Runs homozygosity (ROH) islands overlapped with significantly associated regions detected several Breeders may exploited these to select promising breeders, increasing homozygosity. These results suggest that combining genotypic benefits apples. Information on could beneficial improving apples; however, analysis is required elucidate relationship between depression (e.g. decreased vigor).

Abstract New crop`s need to emerge provide sustainable solutions climate change and increasing abiotic biotic constraints on agriculture. A large breadth of northern fruit trees shrubs exhibit a high potential for domestication; however, obstacles implementing traditional breeding methods have hampered or dissuaded efforts improvement. This review article proposes unique roadmap de novo domestication crops, with focus biotechnological (e.g. genome editing, rapid cycle breeding, in planta transformation) approaches that can boast evolutionary gains. In addition, numerous virus-induced flowering grafting-mediated flowering) strategies adaptation speed trees) hasten the transition from juvenility sexual maturity are described. description an accelerated genetic strategy insights 16 underutilized species shagbark hickory, running serviceberry, horse chestnut, black walnut) is provided support their enhancement. Deemed unrealistic only decade ago, progress realm bioengineering heralds future orphan crops through implementation fast-tracked crop improvement programs. As such, presented this paves way integrating these novel discoveries propel development forgotten timely manner.

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(2), P. 1142 - 1142

Published: Jan. 17, 2024

Real-time quantitative polymerase chain reaction (qRT-PCR) has been widely used in gene expression analyses due to its advantages of sensitivity, accuracy and high throughput. The stability internal reference genes progressively emerged as a major factor affecting the precision qRT-PCR results. However, needs be determined further different cells or organs, physiological experimental conditions. Methods for evaluating these candidate have also evolved from simple single software evaluation more reliable accurate by combining tools comprehensive analysis.

Genomic prediction for rust resistance in pea

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: July 23, 2024

Genomic selection (GS) has become an indispensable tool in modern plant breeding, particularly for complex traits. This study aimed to assess the efficacy of GS predicting rust ( Uromyces pisi ) resistance pea Pisum sativum ), using a panel 320 accessions and set 26,045 Silico-Diversity Arrays Technology (Silico-DArT) markers. We compared prediction abilities different models explored impact incorporating marker × environment (M×E) interaction as covariate GBLUP (genomic best linear unbiased prediction) model. The analysis included phenotyping data from both field controlled conditions. assessed predictive accuracies cross-validation strategies efficiency single traits versus multi-trait index, based on factor ideotype-design (FAI-BLUP), which combines model, when modified include M×E interactions, consistently outperformed other models, demonstrating its suitability affected by genotype-environment interactions (GEI). ability (0.635) was achieved FAI-BLUP approach within Bayesian Lasso (BL) inclusion significantly enhanced accuracy across diverse environments although it did not markedly improve predictions non-phenotyped lines. These findings underscore variability due GEI effectiveness approaches addressing Overall, our illustrates potential GS, especially employing index like accounting breeding programs focused resistance.
