MetabolomicsRhizosheath-associated Massilia contributes to maize growth heterosis

Heterosis, or hybrid vigor, refers to the phenomenon where F1 hybrids outperform their parental inbred lines. Despite more than a century of intensive research across various species, the genetic basis and environmental regulation of heterosis, particularly belowground, remain poorly understood. ...

MetabolomicsMetabolome-based prediction of yield heterosis contributes to the breeding of elite rice
The improvement of breeding efficiencies for heterotic and climate-resilient crops can mitigate the food shortage crisis from overpopulation and climate change. Thus far, diverse molecular markers have been utilized for guiding field phenotypic selections, while the accurate predictions of complex h...

TranscriptomicsTranscriptome Analysis of Rice Root Heterosis by RNA-Seq
Heterosis is a phenomenon that hybrids exhibit superior performance relative to the parental phenotypes. However, most studies focused on aboveground agronomic traits. Thus, systematic investigation on root heterosis, particularly at reproductive stage in rice is needed to be carried out. The recent...

TranscriptomicsDistinct small RNA populations act antagonistically in formation of heterosis
This research reports the analysis of sRNAs in 14 and 7 inbred lines from a breeding population. We analyzed the contribution of sRNAs to the formation of heterosis via integrative association analysis with field data of 98 hybrids generated from the set of inbred lines. Our results indicate a contr...

TranscriptomicsNatural Variation and Timing of Stress Responses Promote and Predict Heterosis
Hybrid plants and animals grow larger and more vigorously than the parents, a common phenomenon known as hybrid vigor or heterosis. Heterosis often correlates with the genetic distance between hybridizing parents, but the mechanism for this is largely unknown. We found that genetic distance was corr...

ProteomicsDifferentially abundant proteins associated with heterosis in the primary roots of popcorn
Although heterosis has significantly contributed to increases in worldwide crop production, the molecular mechanisms regulating this phenomenon are still unknown. In the present study, we used a comparative proteomic approach to explore hybrid vigor via the proteome of both the popcorn L54 ♀ and P8 ...

TranscriptomicsSimilar patterns of additive and non-additive gene expression in maize hybrids with varying levels of heterosis - 70mer
Expression profiling analyses for 5 maize inbreds and 4 hybrids, chosen to represent diversity in genotypes and heterosis responses, revealed a correlation between genetic diversity and transcriptional variation. This is a companion dataset to an Affymetrix profiling experiment (GEO Series GSE10236)...

ProteomicsThe parallel reaction monitoring assays in heterosis of hybrid yellow catfish Huangyou-1
Heterosis is a complex biological phenomenon in which hybridization exhibits superior phenotypic characteristics. The underlying molecular basis for heterosis, particularly for fishes, remains elusive. The utilization rate of fish heterosis far exceeds our understanding of it on a theoretical level....

ProteomicsConjoint analysis of transcriptional and protein changes in heterosis of hybrid yellow catfish Huangyou-1 uncovers key roles for miRNAs
Heterosis is a complex biological phenomenon in which hybridization exhibit superior phenotypic characteristics. The underlying molecular basis for heterosis, particularly for fishes, remains elusive. In this study, we used next-generation sequencing technologies and tandem mass tags to characterise...
