Due to the low incidence of precipitation attributed climate change, many high-altitude Andean lakes (HAALs) and lagoons distributed along central Andes in South America may soon disappear. This includes La Brava-La Punta, a brackish lake system located south Salar de Atacama within hyper-arid halophytic biome Desert. Variations physicochemical parameters water column can induce changes microbial community composition, which we aimed determine. Sixteen sampling points across Punta were...
The woody nature of grapevine ( Vitis vinifera L.) has hindered the development efficient gene editing strategies to improve this species. lack highly transfer techniques, which, furthermore, are applied in multicellular explants such as somatic embryos, additional technical handicaps vine. inclusion geminivirus-based replicons regular T-DNA vectors can enhance expression clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) elements, thus...
Cherimoya (Annona cherimola Mill.) fruit is an attractive candidate for food processing applications as fresh cut. However, along with its desirable delicate taste, cherimoya shows a marked susceptibility to browning. This condition mainly attributed polyphenol oxidase activity (PPO). A general lack of knowledge regarding PPO and role in the oxidative loss quality processed requires better understanding mechanisms involved. The work carried out included cloning full-length cDNA, analysis...
In plants, host factors encoded by susceptibility (S) genes are indispensable for viral infection. Resistance is achieved through the impairment or absence of those factors. Many S have been cloned from model and crop species a majority them coding members eukaryotic translation initiation complex, mainly eIF4E, eIF4G their isoforms. The aim this study was to investigate role in stone fruit sharka, disease due Plum pox virus (PPV).For purpose, hairpin-inducing silencing constructs based on...
The nematode Xiphinema index affects grape vines and transmits important viruses associated with fanleaf degeneration. Pseudomonas spp. are an extensive bacterial group in which biodegradation and/or biocontrol properties can occur for several strains the group. aim of this study was to identify new isolates antagonist activity against X. index. Forty were obtained from soil root samples Chilean vineyards. Thirteen fluorescent pseudomonads found assessed their antagonistic capability....
A new species of mealybug from Chile, Pseudococcus meridionalis Prado sp. n., is described and illustrated based on the morphological molecular characterization adult females. This belongs to “Pseudococcus maritimus” complex displays a wide host plant range, including Japanese pear, persimmon, pomegranate, pear grape.
Summary The potential impact of genetically modified ( GM ) crops on biodiversity is one the main concerns in an environmental risk assessment ERA ). likelihood outcrossing and pollen‐mediated gene flow from non‐ are explained by same principles depend primarily biology species. We conducted a national‐scale study between 11 vascular plants Chile use systematized database that included cultivated, introduced native plant species Chile. geographical distributions key biological agronomical...

Doce cultivares y lineas de arroz (Oryza sativa L.) desarrollados por el programa fitomejoramiento del Instituto Investigaciones Agropecuarias (INIA), Centro Regional Investigacion Quilamapu, fueron caracterizados geneticamente mediante amplificacion fragmentos polimorficos (AFLP). De 21 combinaciones ensayadas, solo 16 informativas, generando un total 667 amplicones, 94 ellos (14,4%), con rango entre 9 33% polimorfismo combinacion. Esto indica que material manejado INIA presenta bajo nivel...
In potato (Solanum tuberosum L.), protoplast techniques are limited to a few genotypes; thus, the use of regular regeneration procedures multicellular explants causes us face complexities associated CRISPR/Cas9 gene editing efficiency and final identification individuals. Geminivirus-based replicons contained in T-DNAs could provide an improvement these considering their cargo capability. We built Bean yellow dwarf virus-derived replicon vector, pGEF-U, that expresses all reagents under...
Many genetic studies in insects require sex identification of individuals all developmental stages. The most common chromosome system lepidopterans is WZ/ZZ; the W present only females. Based on two chromosome-specific short sequences (CpW2 and CpW5) described Cydia pomonella (L.) (Lepidoptera: Tortricidae), we identified homologous female-specific Lobesia botrana Den. & Schiff, a polyphagous very harmful species Chile since 2008. From this starting point, extended sequence information using...
Abstract Rapid and cost-efficient identification of Naupactus species is becoming a key process for the exportation citrus fruit from Chile other countries, considering quarantine regulations some cosmopolitan genus Naupactus. This study deals with development fast sensitive detection protocol cervinus (Coleoptera: Curculionidae) (Boheman) xanthographus (Germar) based on multiplex TaqMan Real-time polymerase chain reaction. Both N. primer probe sets achieved species-specific in linear range...
Abstract A national‐scale study of outcrossing potential within Chilean vascular flora was conducted using an upgraded algorithm, which adds parameters such as pollinator agents, climate, and geographic conditions. Datasets were organized linked in a Web platform ( www.flujogenico.cl ), the development total TOP ) predictor formulated. The is engine platform, models effect type agricultural practice on others (coexistence calculation mode) environment (biodiversity mode). scale for results...
Algarrobilla (Balsamocarpon brevifolium, Fabaceae) is an endemic xerophytic shrub restricted to the Atacama Desert in northern Chile. Extensive utilization of region for coal production has endangered this species. Conservation efforts are underway, with genetic diversity analyses being key restoration these populations.Fifteen new microsatellite markers were developed B. brevifolium and used analyze three populations from Coquimbo regions Microsatellites highly polymorphic, average 5.77...
During the summer 1995, at Experimental and Training Station of Agronomy School University El Salvador, an experiment was established by alternating sword bean (0.80 m. x 0.50 m) with maize 0.30 m.), under zero management. The plot divided in two areas one a high infestation “coyolillo” other predominance wide-leaf weeds, such as Baltimora recta, Melantera sp., Lantana camara, Panicum sp. Samples were taken each area every 10 days, using plants to determine following variables: plant height,...
