“…After fibre extraction the residue is usually discarded [18]. This residue accounts for 98% of the total biomass of the plant and has potential to be used as raw material for biofuels, especially because it is not directly used as food [6,12,19]. In order to exploit the economic value of this material, a joint initiative between the Common Fund for Commodities, the United Nations Industrial Development Organization (UNIDO) and the Tanzanian sisal industry financed the first commercial plant for the production of biogas [12].…”

“…In addition to some medicinal properties reported [20,21], A. sisalana also produces compounds that have different biological properties [18] of great interest in the pharmaceutical industry such as hecogenin [12,[21][22][23]. All of the above features place sisal as a strategic species to be exploited in tropical semiarid regions and in temperate latitudes with drought resulting from global climate change [16,19,24].…”

Sisal (Agave sisalana) is one of the main sources of hard natural fibre and raw materials for the industry, medicine and handicrafts. Sisal yields a coarse and strong fibre that is increasingly being used in composite materials for automobiles, furniture, construction and plastic and paper products. Extracts of sisal contain substances with anti-inflammatory, antimicrobial and anthelmintic activities. Sisal is adapted to warm environments with low rainfall and is an excellent option for cultivation in semiarid conditions, where other crops cannot be grown. The world's largest sisal producers are Brazil, Tanzania, China, Kenya and Madagascar. Sisal is a labour-intensive crop with great socio-economical importance as it is cultivated in poor areas employing familiar labour. Sisal bole rot is the main disease of sisal, responsible for substantial losses in producing countries. The disease is caused by certain species of the genus Aspergillus, especially the ones belonging in the section Nigri. The main symptoms are yellowing of the aerial parts and the red-coloured rot of the bole, which causes the plant to die. In this review we are going to address the taxonomy of the causal agents, disease diagnosis and epidemiology and disease management, with emphasis on biological control.

“…The groups Rigidae and Sisalanae that belong to the subgenus Agave, are commercially important due to their use for several purposes: (a) alcoholic beverages, such as tequila and mezcal; (b) natural long and hard ibers; and (c) steroidal and medicinal principles [2][3][4]. The Agave genus conforms a group of plant species of the Asparagaceae family (formerly Agavaceae) that belongs to the monocot class of angiosperms and because of its CAM metabolism and other botanical features, the genus Agave is gaining importance throughout the world to address the challenges that climate change is imposing with regard to food, medicine and bioenergy [4].…”

Chromatid Abnormalities in Meiosis: A Brief Review and a Case Study in the Genus Agave (Asparagales, Asparagaceae)

The genus Agave is distributed in the tropical and subtropical areas of the world and represents a large group of succulent plants, with about 200 taxa from 136 species, and its center of origin is probably limited to Mexico. It is divided into two subgenera: Litaea and Agave based on the architecture of the inlorescence; the subgenus Litaea has a spicate or racemose inlorescence, while plants of the subgenus Agave have a paniculate inlorescence with lowers in umbellate clusters on lateral branches. As the main conclusion of this study, a hypothesis rises from the described observations: frying pan-shaped chromosomes are formed by sister chromatid exchanges and a premature kinetochore movement in prophase II, which are meiotic aberrations that exist in these phylogenetic distant species, Agave stricta and A. angustifolia since ancient times in their evolution, and this may be due to genes that are prone to act under diverse kinds of environmental stress.

Species of the genus Agave are distributed originally in the tropical and subtropical areas of the American continent with about 200 taxa and 136 species, and its center of origin is probably limited to México. These kind of plants usually grow and live in extreme environmental conditions such as heat and drought where their CAM pathway for fixing CO allow them to survive in conditions where other plants cannot survive. Although this kind of plants resist harsh environmental conditions, climate change is imposing stronger kinds of stress that diminish their productive potential and in some cases are cause of death. Because of this, genetic improvement becomes a need of fundamental importance in this kind of species. Despite their economic importance, Agave species have received scarce attention with regard to its genetic improvement, probably due to their unique botanical features such as plant architecture, spines, long life span, and monocarpy, among others, which make hybridization a difficult task for the intra- and interspecific gene transfer and creation of genetic variability among many other breeding techniques.The protocol here presented is a combination of a novel hybridization technique and biotechnological tools, and allows the use of several procedures for the genetic improvement of agaves such as pollen selection, clonal selection, and somatic cell selection, among others, since the rescued embryos can be used for micropropagation, for phenotype/genotype selection or the production of cell lineages for diverse genetic improvement purposes.
