Abstract The Dahlia (Dahlia coccinea Cav.) is a plant that has been cultivated and genetically improved due to its ornamental importance; anyhow, its radical system accumulates reserve carbohydrates in the form of inulin and other fructans. Inulin is considered a part of the dietetic fiber from vegetable food sources, and it is also considered as a prebiotic compound. Inulin is extracted mainly from chicory and artichoke through different separation methods being Dahlia’s tubers an interesting option for industrial utilization. The aims of this study were to (1) propose a simple extraction method of inulin from Dahlia’s tubers, and (2) evaluate the… More >

Abstract The genus Dasylirion is a group of plants typically present in the Chihuahuan Desert, perennial, with a dioecious sexual behavior and commonly called sotoles. This genus has been little studied from the biological point of view, and the bases of its reproductive response remain unknown. In this work we studied the chromosome number and meiotic response of Dasylirion cedrosanum in the county of Saltillo, Coahuila, located at the North East of Mexico. For the preparation of mitotic chromosomes, we used a technique based on enzymatic treatment with pectolyase and cellulase, as well as staining with acetocarmin dye. For the study… More >

Abstract The cultivated husk tomato (Physalis ixocarpa) (2n = 2x = 24) is native from Mexico and Central America and shows a wide genetic variation. Presently, it is the fourth horticultural crop in cultivation surface in Mexico. The working team of this research previously developed an autotetraploid population by using colchicine. The objectives of the present work were to analyze the ploidy level and meiotic behavior of the subsequent generations (C3, C4, C5, C6) from the original (C2) composed only by plants with the duplicated genome from the Rendidora cultivar, and to determine pollen viability. As a diploid control the cultivar… More >

Abstract Mexico counts among the five countries with the highest biodiversity in the world. In the Yucatán Peninsula, there are aquatic ecosystems with a very special microbial diversity. These ecosystems are essential for the ecological equilibrium of the region, and are seriously threatened by human activities. Access and knowledge of the microbial resources of these environments have an enormous scientific interest, and could potentially result in biotechnological products which could lead to more efficient and environmentally friendly processes; it could also offer a full arsenal of microorganisms and/or novel molecules to the local and world industry to face the current needs.… More >

Abstract Soil is a complex system that includes a great number and diversity of microorganisms. Until recently, only a small percentage of the bioma was known and could be studied. Currently, it is possible to have a deeper knowledge of all that unknown genomic material with the development of new tools, like metagenomics. New molecules have been discovered with various biotechnological applications, and knowledge of the diverse microbiological interactions in several environments, some of them with extreme life conditions, is much higher. We analyze the most recent literature in the field of metagenomics in this study, especially that related with the… More >

Abstract Transcription factors (TFs) are proteins able to specifically recognize DNA sequences in the regulatory regions of their target genes. They bind these specific sequences, an event that leads to the activation or repression of whole signal transduction pathways. In plants about 1500 TFs were informatically identified; identification was mainly based in the presence of DNA-binding domains in the translated sequences. They were classified in families and subfamilies according to several features, including the conservation of the DNA binding domain, the genes structures and the functions they exert. Among transcription factors, several seem to be potential powerful biotechnological tools to improve… More >

Abstract Seed inoculation with bacterial species has the potential to increase yield and agro-qualitative attributes of forage crops. This study determined the response of forage maize to three plant growth promoting rhizobacteria [PGPR1 (Azotobacter chroococcum), PGPR2 (Pseudomonas flourescens) and PGPR3 (Bacillus megaterium)] inoculated individually and in different combinations (PGPR1+2, PGPR1+3, PGPR2+3 and PGPR1+2+3). A non-inoculated treatment was kept as a control. We used a completely randomized block design with four replicates. The PGPR1+2+3 treatment showed an outstanding performance by improving yield attributes, green forage yield, dry matter biomass, crude protein and total ash. The same treatment gave the lowest crude fiber… More >

Abstract With the rapid development of artificial intelligence, face recognition systems are widely used in daily lives. Face recognition applications often need to process large amounts of image data. Maintaining the accuracy and low latency is critical to face recognition systems. After analyzing the two-tier architecture “client-cloud” face recognition systems, it is found that these systems have high latency and network congestion when massive recognition requirements are needed to be responded, and it is very inconvenient and inefficient to deploy and manage relevant applications on the edge of the network. This paper proposes a flexible and efficient edge computing accelerated architecture.… More >

Abstract The speech recognition technology has been increasingly common in our lives. Recently, a number of commercial smart speakers containing the personal assistant system using speech recognition came out. While the smart speaker vendors have been concerned about the intelligence and the convenience of their assistants, but there have been little mentions of the smart speakers in security aspects. As the smart speakers are becoming the hub for home automation, its security vulnerabilities can cause critical problems. In this paper, we categorize attack vectors and classify them into hardware-based, network-based, and software-based. With the attack vectors, we describe the detail attack… More >
