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.

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.
