“…A phylogenetic analysis of the tribe Myrteae ( Vasconcelos et al, 2017 ) suggested that the most recent common ancestor of the genera Psidium , Myrrhinium Schott and Mosiera Small [named Psidium group in Vasconcelos et al, 2017 and part of the current Pimentinae subtribe in Lucas et al, 2019 ] dates to 25.62 mya, during the Oligocene. Today, we know that a progressive decline in temperature since the Oligocene and the subsequent climatic fluctuations during the middle-Miocene, caused the megathermal angiosperms (e.g., Myrtaceae) to migrate toward lower latitudes ( Panti, 2016 ) from their former range at the southern tip of Patagonia.…”

Guava (Psidium guajava L., Myrtaceae) is a Neotropical fruit that is widely consumed around the world. However, its evolutionary history and domestication process are unknown. Here we examine available ecological, taxonomic, genetic, archeological, and historical evidence about guava. Guava needs full sunlight, warm temperatures, and well-distributed rainfall throughout the year to grow, but tolerates drought. Zoochory and anthropochory are the main forms of dispersal. Guava’s phylogenetic relationships with other species of the genus Psidium are unclear. A group of six species that share several morphological characteristics are tentatively accepted as the Psidium guajava complex. DNA analyses are limited to the characterization of crop genetic diversity within localities and do not account for possible evolutionary and domestication scenarios. A significant amount of archeological information exists, with a greater number and older records in South America than in Mesoamerica, where there are also numerous historical records. From this information, we propose that: (1) the guava ancestor may have originated during the Middle or Late Miocene, and the savannas and semi-deciduous forests of South America formed during the Late Pleistocene would have been the most appropriate ecosystems for its growth, (2) the megafauna were important dispersers for guava, (3) dispersal by humans during the Holocene expanded guava’s geographic range, including to the southwestern Amazonian lowlands, (4) where its domestication may have started, and (5) with the European conquest of the Neotropics, accompanied by their domestic animals, new contact routes between previously remote guava populations were established. These proposals could direct future research on the evolutionary and domestication process of guava.

“…Myrtaceae (Myrtales) tem distribuição pantropical (Wilson et al 2001, Judd et al 2009), com centros de diversidade na Austrália, sudeste da Ásia, sul da América tropical e poucos representantes na África (Wilson et al 2001), circunscrita a 145 gêneros e aproximadamente 6.000 espécies (Lucas et al 2019). Segundo a classificação mais recente proposta por Wilson et al (2005), para Myrtaceae são reconhecidas duas subfamílias, Psiloxyloideae e Myrtoideae, com um total de 17 tribos.…”

RESUMO -Apresentamos o estudo taxonômico das espécies de Myrtaceae do litoral da Ilha do Maranhão. A Ilha está situada no extremo norte do Estado, no centro do "Golfão Maranhense" e contempla quatro municípios: São José de Ribamar, São Luís, Paço do Lumiar e Raposa. O estudo foi realizado com base na análise dos espécimes coletados entre 2016 e 2018 em oito áreas de dunas (Dunas da praia de Araçagi, Guia, Caolho e São Marcos) e restingas (Restinga da praia de Caúra, Ilha de Curupu, Panaquatira e Sítio Aguahy), além de análise do material depositado no acervo do Herbário do Maranhão (MAR). Foram registradas 16 espécies compreendendo seis gêneros. O estudo inclui chaves de identificação das espécies, descrições, ilustrações, comentários sobre semelhanças morfológicas, dados de distribuição fitogeográfica e informações sobre a fenologia reprodutiva.

Psidium friedrichsthalianum (O. Berg) Nied is a tropical tree species in the Myrtaceae family, natively distributed from southern Mexico, to eastern Venezuela and Ecuador and commonly known as "Cas'', "Costa Rican guava" or “Sour Guava”. The “Cas” produces a fruit with a rather distinctive acidic flavor and has bioactive compounds and biological potential equal or greater than common Guava; is considered an indigenous crop in Costa Rica with characteristics as a functional food untapped. This species has not been completely domesticated, and can be found in home gardens, paddocks, small groups, and, more recently, in small and medium sized plantations. Also, the plantations of this species do not have technical and scientific support or agronomic promotion from industry, nor are there genetic resources or germplasm readily available to farmers. This limits its commercial development and the implementation of selection or genetic improvement programs. In this study, we present the first draft assembly of the Cas genome using PacBio long reads and the Canu assembly pipeline. Our draft assembly has a total length of 417.64 Mb, with 24 440 contigs and a N50 contig size of 21.3 Kb. Structural annotation resulted in 59 036 gene models. Functional annotation was conducted against the non-redundant set of genes from the KEGG database. Of the 52 422 complete genes models, 15.55% (8 153) presented homology with KEGG orthologs. The genes found in our Cas draft assembly were compared to those found in Eucalyptus grandis (rose gum) [erg] in the KEGG repository. According to the KEGG pathway assignments, 33 isoforms were annotated as part of the flavonoid biosynthetic pathway. In addition, 19 isoforms were annotated as part of phenylpropanoid biosynthetic pathway. The results of this study provide an overview of the first draft of the Cas genome assembly using PacBio long reads. This new genomic resource represents the basis for exploring the genetic potential of this crop with characteristics as a functional food.
