Abstract The Cyanidiophyceae, an extremophilic red algal class, is distributed worldwide in extreme environments. Species grow either acidic hot environments or dim light conditions (e.g., “cave Cyanidium ”). taxonomy and classification systems are currently based on morphological, eco‐physiological, molecular phylogenetic characters; however, previous results showed hidden diversity of the Cyanidiophyceae suggested a revision system. To clarify relationships within this we employ...

The genus Beauveria is considered a cosmopolitan anamorphic and teleomorphic of soilborne necrotrophic arthropod-pathogenic fungi that includes ecologically economically important species. Species identification in difficult because its structural simplicity the lack distinctive phenotypic variation. Therefore, use multi-locus sequence data essential to establish robust species boundaries addition DNA-based delimitation methods using genetic distance, coalescent, genealogical concordance...

Cacao (Theobroma cacao L.) is the basis of lucrative confectionery industry with “fine or flavour” cocoa attracting higher prices due to desired sensory and quality profiles. The Amazonas Region (north Peru) has a designation origin, Fine Aroma Cacao, based on quality, productivity morphological descriptors but its genetic structure ancestry underexplored. We genotyped 143 trees from northern Peru (Bagua, Condorcanqui, Jaén, Mariscal Cáceres, Utcubamba; mainly Region), using 192 single...

Theobroma cacao is the most economically important species within genus Theobroma. Despite its importance, intraspecific relationships of this has not been fully elucidated due to insufficient molecular information. To facilitate a better understanding evolutionary T. cacao, Sequencing technology decode plastid genomes, with objective identify potential DNA barcode genetic markers, explore relationships, and infer divergence times. The genome seven cocoa genotypes analyzed in study,...

Abstract:We conducted phylogenetic analyses of plastid rbcL sequences and detailed observations on female reproductive structures foliose halymeniacean red algae collected in Chile Peru. We describe Ramirezia osornoensis gen. et. sp. nov., characterised by having seven-celled carpogonial branches six-celled auxiliary-cell branches, formation primary connecting filaments after fertilisation, nutritive mostly upwardly directed well-developed pericarps. It was distributed from central to the...

Previous studies on the biological integrity habitat and landuse patterns demonstrated ecological stream health in view of regional or macrohabitat scale, thus ignored mesoscale pool, riffle, runs analysis. The objective this study was to analyze influences mesohabitat structures run reaches fish guilds Geum-River Watershed. influenced along with some close relations trophic tolerance guilds. components altered chemical water quality such as nutrients (TN, TP) BOD these, then, determined...

A partial rbc L sequence of the lectotype specimen Corallina berteroi shows that it is earliest available name for C . ferreyrae Multilocus species delimitation analyses (ABGD, SPN, GMYC, bPTP, and BPP) using independent or concatenated COI, psb A, sequences recognized one, two, three in this complex, but only with weak support each hypothesis. Conservatively, we recognize a single worldwide complex what appears to be multiple, evolving populations. Included species, besides C. , are...

The assignment of accurate species names is crucial, especially for those with confirmed agronomic potential such as highland papayas. use additional methodologies and data sets recommended to establish well-supported boundaries among Vasconcellea . Accordingly, six chloroplast ( trnL - trnF , rpl20 rps12 psbA trnH intergenic spacers, matK rbcL genes) nuclear (ITS) markers were used delimit in the genus using phylogeny four DNA-based methods. Our results demonstrated congruence different...

:The taxonomy of Grateloupia sensu lato from South America is still to be fully resolved. Based on the phylogeny rbcL and female reproductive structures, we described a new genus, Neorubra, contain two Peruvian species previously known as denticulata Prionitis decipiens. Neorubra was characterised by having five-celled carpogonial branches four-celled auxiliary-cell branches, fusion carpogonia hypogynous cells that formed basal cell or third branch, markedly elongated pericarps were well...

The hyperdiverse genus Trichoderma is one of most useful groups microbes for a number human activities, and their accurate identification crucial. structural simplicity lack distinctive phenotypic variation in this group enable the use DNA-based species delimitation methods combination with phylogenies (and morphology when feasible) to establish well-supported boundaries among species. Our study employed multilocus phylogeny four (automated barcode gap discovery [ABGD], statistical parsimony...

We investigated species in the family Phyllophoraceae from Korea using nuclear large-subunit ribosomal RNA, mitochondrial COI and plastid rbcL sequences morphological examination. To understand taxonomic relationships of Korean Ahnfeltiopsis, we also analysed topotype materials A. leptophylla Besa papillaeformis California. Both individual combined datasets revealed that Ahnfeltiopsis (except flabelliformis) consistently formed a clade with Californian strong support, this was distinct other...

Abstract The time of the fermentation process coffee from northern Peru is variable (9 to 48 hours) since farmers do not use standardized processes, causing a variety qualities. This study aimed identify volatile compounds in both short and long (32 processes farms using Solid-Phase Microextraction-Gas Chromatography/Mass Spectrometry (SPME-GC/MS) associate quality diversity compounds. Sensory analyses showed that (SFP) scored 77.8 ± 0.39 had chocolate, wood, cardboard, dry, fatty rough...

Macroalgae are vital reservoirs for essential epibiotic microorganisms. Among these growth-promoting bacteria that support the growth and healthy development of their host macroalgae, macroalgae can be utilized in agriculture as biostimulants, offering an alternative to traditional agrochemicals. However, date, no comparative studies have been conducted on functional profile bacterial diversity associated with coastal Peru. In this study, we employed amplicon sequencing V3-V4 region 16S rRNA...

High-throughput sequencing of an isotype specimen Corallina ferreyrae from Peru resulted in the assembly its complete mitogenome (GenBank accession number MK408747) and plastid genome MK408748). The is 25,953 bp length contains 48 genes. 176,889 233 organellar genomes share a high-level gene synteny to other Corallinales. Genetic analysis standard marker sequences C. reveals it conspecific with caespitosa. has priority publication over caespitosa, which we hereby propose as heterotypic...
