| highly efficient mesophyll protoplast isolation and peg-mediated transient gene expression for rapid and large-scale gene characterization in cassava (manihot esculenta crantz). | cassava (manihot esculenta crantz) is a major crop extensively cultivated in the tropics as both an important source of calories and a promising source for biofuel production. although stable gene expression have been used for transgenic breeding and gene function study, a quick, easy and large-scale transformation platform has been in urgent need for gene functional characterization, especially after the cassava full genome was sequenced. | 2017 | 28292294 |
| cyanogen metabolism in cassava roots: impact on protein synthesis and root development. | cassava (manihot esculenta crantz), a staple crop for millions of sub-saharan africans, contains high levels of cyanogenic glycosides which protect it against herbivory. however, cyanogens have also been proposed to play a role in nitrogen transport from leaves to roots. consistent with this hypothesis, analyses of the distribution and activities of enzymes involved in cyanide metabolism provides evidence for cyanide assimilation, derived from linamarin, into amino acids in cassava roots. both β ... | 2017 | 28286506 |
| global gene expression analysis reveals crosstalk between response mechanisms to cold and drought stresses in cassava seedlings. | abiotic stress negatively impacts cassava (manihot esculenta) growth and yield. several molecular mechanisms of plant response to cold and drought have been identified and described in the literature, however, little is known about the crosstalk of the responses of cassava to these two stresses. to elucidate this question, transcriptome analysis of cassava seedlings under cold or peg-simulated drought stress treatment was performed. our results showed that 6103 and 7462 transcripts were signific ... | 2017 | 28769962 |
| overexpression of arabidopsis flowering locus t (ft) gene improves floral development in cassava (manihot esculenta, crantz). | cassava is a tropical storage-root crop that serves as a worldwide source of staple food for over 800 million people. flowering is one of the most important breeding challenges in cassava because in most lines flowering is late and non-synchronized, and flower production is sparse. the flowering locus t (ft) gene is pivotal for floral induction in all examined angiosperms. the objective of the current work was to determine the potential roles of the ft signaling system in cassava. the arabidopsi ... | 2017 | 28753668 |
| the pre-columbian introduction and dispersal of algarrobo (prosopis, section algarobia) in the atacama desert of northern chile. | archaeological and palaeoecological studies throughout the americas have documented widespread landscape and environmental transformation during the pre-columbian era. the highly dynamic formative (or neolithic) period in northern chile (ca. 3700-1550 yr bp) brought about the local establishment of agriculture, introduction of new crops (maize, quinoa, manioc, beans, etc.) along with a major population increase, new emergent villages and technological innovations. even trees such as the algarrob ... | 2017 | 28742126 |
| blood lead levels and risk factors for lead exposure among pregnant women in western french guiana: the role of manioc consumption. | concerns regarding lead (pb) poisoning in french guiana first arose in 2011 following the discovery of excessively high levels of the metal amongst children in a small neighborhood without any apparent source of pb. since 2012, blood lead level (bll) measurement has been proposed for all pregnant women in western french guiana. the aim of this study was to determine bll in pregnant women in this region and identify factors associated with elevated bll. an observational study of a consecutive sam ... | 2017 | 28644767 |
| morphological changes of blocklets during the gelatinization process of tapioca starch. | after combined hydrolysis by α-amylase and β-amylase at room temperature, spherical blocklets in diameters of 27-60nm were observed on the surface of tapioca starch granules by scanning electron micrography (sem). tapioca starch (1%, w/w, db, distilled water) was heated by using a rapid visco analyzer (rva) in four different programs, then the samples were settled and freeze dried, respectively. the sem images showed that the blocklets swelled at 52°c; the swollen blocklets deformed to olive sha ... | 2017 | 28267512 |
| cassava c-repeat binding factor 1 gene responds to low temperature and enhances cold tolerance when overexpressed in arabidopsis and cassava. | cassava mecbf1 is a typical cbf transcription factor mediating cold responses but its low expression in apical buds along with a retarded response cause inefficient upregulation of downstream cold-related genes, rendering cassava chilling-sensitive. low temperature is a major abiotic stress factor affecting survival, productivity and geographic distribution of important crops worldwide. the c-repeat/dehydration-responsive element binding transcription factors (cbf/dreb) are important regulators ... | 2017 | 28258553 |
| genome-wide characterization and expression profiling of hd-zip gene family related to abiotic stress in cassava. | homeodomain-leucine zipper (hd-zip) gene family plays important roles in various abiotic stresses and hormone signaling in plants. however, no information is currently available regarding this family in cassava (manihot esculenta), an important drought-tolerant crop in tropical and sub-tropical areas. here, 57 hd-zip genes (mehdz01-57) were identified in the cassava genome, and they were classified into four subfamilies based on phylogenetic analysis, which was further supported by their gene st ... | 2017 | 28249019 |
| the industrial applications of cassava: current status, opportunities and prospects. | cassava (manihot esculenta crantz) is a drought-tolerant, staple food crop that is grown in tropical and subtropical areas. as an important raw material, cassava is a valuable food source in developing countries and is also extensively employed for producing starch, bioethanol and other bio-based products (e.g. feed, medicine, cosmetics and biopolymers). these cassava-based industries also generate large quantities of wastes/residues rich in organic matter and suspended solids, providing great p ... | 2017 | 28233322 |
| flowering locus t triggers early and fertile flowering in glasshouse cassava (manihot esculenta crantz). | accelerated breeding of plant species has the potential to help challenge environmental and biochemical cues to support global crop security. we demonstrate the over-expression of arabidopsisflowering locus t in agrobacterium-mediated transformed cassava (manihot esculenta crantz; cultivar 60444) to trigger early flowering in glasshouse-grown plants. an event seldom seen in a glasshouse environment, precocious flowering and mature inflorescence were obtained within 4-5 months from planting of st ... | 2017 | 28555003 |
