Abstract. Single nucleotide polymorphisms (SNPs) located in transcript sequences showing allele-specific expression (ASE SNPs) were previously identified in the Longissimus thoracis muscle of a Nelore (Bos indicus) population consisting of 190 steers. Given that the allele-specific expression pattern may result from cis-regulatory SNPs, called allele-specific expression quantitative trait loci (aseQTLs), in this study, we searched for aseQTLs in a window of 1 Mb upstream and downstream from each ASE SNP. After this initial analysis, aiming to investigate variants with a potential regulatory role, we further screened our aseQTL data for sequence similarity with transcription factor binding sites and microRNA (miRNA) binding sites. These aseQTLs were overlapped with methylation data from reduced representation bisulfite sequencing (RRBS) obtained from 12 animals of the same population. We identified 1134 aseQTLs associated with 126 different ASE SNPs. For 215 aseQTLs, one allele potentially affected the affinity of a muscle-expressed transcription factor to its binding site. 162 aseQTLs were predicted to affect 149 miRNA binding sites, from which 114 miRNAs were expressed in muscle. Also, 16 aseQTLs were methylated in our population. Integration of aseQTL with GWAS data revealed enrichment for traits such as meat tenderness, ribeye area, and intramuscular fat . To our knowledge, this is the first report of aseQTLs identification in bovine muscle. Our findings indicate that various cis-regulatory and epigenetic mechanisms can affect multiple variants to modulate the allelic expression. Some of the potential regulatory variants described here were associated with the expression pattern of genes related to interesting phenotypes for livestock. Thus, these variants might be useful for the comprehension of the genetic control of these phenotypes. MenosAbstract.

Cotton (Gossypium spp.) is the most important crop for natural textile fiber production worldwide. Nonetheless, one of the main challenges in cotton production are the losses resulting from insect pests, pathogens, and abiotic stresses. One effective way to solve these issues is to use genetically modified (GM) varieties. Herein, we describe an improved protocol for straightforward and cost-effective genetic transformation of cotton embryo axes, merging biolistics and Agrobacterium. The experimental steps include (1) Agrobacterium preparation, (2) seed sterilization, (3) cotton embryo excision, (4) lesion of shoot-cells by tungsten bombardment, (5) Agrobacterium-mediated transformation, (6) embryo co-culture, (7) regeneration and selection of transgenic plants in vitro, and (8) molecular characterization of plants. Due to the high regenerative power of the embryonic axis and the exceptional ability of the meristem cells for plant regeneration through organogenesis in vitro, this protocol can be performed in approximately 4?10 weeks, with an average plant regeneration of about 5.5% (±?0.53) and final average transformation efficiency of 60% (±?0.55). The transgene was stably inherited, and most transgenic plants hold a single copy of the transgene, as desirable and expected in Agrobacterium-mediated transformation. Additionally, the transgene was stably expressed over generations, and transgenic proteins could be detected at high levels in the T2 generation of GM cotton plants. The T2 progeny showed no phenotypic or productivity disparity compared to wild-type plants. Collectively, the use of cotton embryo axes and the enhanced DNA-delivery system by combining particle bombardment and Agrobacterium infection enabled efficient transgenic plant recovery, overcoming usual limitations associated with the recalcitrance of several cotton genotypes subjected to somatic embryogenesis. The improved approach states this method?s success for cotton genetic modification, allowing us to obtain GM cotton plants carrying traits, which are of fundamental relevance for the advancement of global agribusiness.
