Genome-wide association insights into the genomic regions controlling vegetative and oil production traits in Acrocomia aculeata.

Article Synopsis
- Macauba (Acrocomia aculeata) is a promising non-domesticated palm species with potential for oil production, comparable to the commercially used oil palm, driving interest in its genetic study for domestication efforts.
- The study utilized various genotyping strategies to identify SNPs in 201 palms and performed GWAS to associate genetic traits with vegetative and oil production characteristics, despite lacking a reference genome.
- Results indicated significant genetic variation among traits, with heritability values suggesting the presence of favorable genotypes for breeding programs; a total of 92 significant SNPs were identified in single-trait GWAS using de novo data.
Acrocomia (Arecaceae) is a genus widely distributed in tropical and subtropical America that has been achieving economic interest due to the great potential of oil production of some of its species. In particular A. aculeata, due to its vocation to supply oil with the same productive capacity as the oil palm (Elaeis guineenses) even in areas with water deficit.

This study aimed to evaluate the genetic variability shown by 63 garlic accessions belonging to Instituto Agronômico de Campinas and the Escola Superior de Agricultura "Luiz de Queiroz" germplasm collections.

September 2015
Background: Passion fruit woodiness may be caused by Cowpea aphid-borne mosaic virus (CABMV) and is currently the major passion fruit disease in Brazil. To assess the virus-vector-host interactions, a newly introduced golden passion fruit plantation located in eastern region of São Paulo State, Brazil, was monitored.
Methods: Dissemination of CABMV was determined analyzing golden passion fruit plants monthly for 18 months by PTA-ELISA.
Article Synopsis
- Acrocomia aculeata is a tropical palm known for its fruit, which has potential applications in cosmetics and biofuels.
- The study investigated the genetic structure and mating system of the species in Brazil, revealing a clustering of populations and a high rate of outcrossing, though some inbreeding was noted.
- Findings suggest the need for conservation strategies to preserve genetic diversity by sampling individuals from different genetic clusters.
