Tnr1 (235 bp long) is a transposable element in rice. Polymerase chain reactions (PCRs) done with a primer(s) that hybridizes to terminal inverted repeat sequences (TIRs) of Tnr1 detected new Tnr1 members with one or two insertions in rice genomes. Six identified insertion sequences (Tnr4, Tnr5, Tnr11, Tnr12, Tnr13 and RIRE9) did not have extensive homology to known transposable elements, rathe...

Launched in February 2013, the Landsat-8 carries on-board the Thermal Infrared Sensor (TIRS), a two-band thermal pushbroom imager, to maintain the thermal imaging capability of the Landsat program. The TIRS bands are centered at roughly 10.9 and 12 μm (Bands 10 and 11 respectively). They have 100 m spatial resolution and image coincidently with the Operational Land Imager (OLI), also on-board L...

This paper presents a Python QGIS (PyQGIS) plugin, which has been developed for the purpose of producing Land Surface Temperature (LST) maps from Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 TIRS, Thermal Infrared (TIR) imagery. The plugin has been developed purposely to ease the process of LST extraction from Landsat Visible, Near Infrared (VNIR) and TIR imagery. It has the ability to estimate L...

Mariner-like elements (MLEs) are DNA transposons found throughout the plant and animal kingdoms. A previous computational survey of the rice (Oryza sativa) genome sequence revealed 34 full length MLEs (Osmars) belonging to 25 distinct families. This survey, which also identified sequence similarities between the Osmar elements and the Stowaway superfamily of MITEs, led to the formulation of a h...

The maize transposon Activator (Ac) was the first mobile DNA element to be discovered. Since then, other elements were found that share similarity to Ac, suggesting that it belongs to a transposon superfamily named hAT after hobo from Drosophila, Ac from maize, and Tam3 from snapdragon. We addressed the structure and evolution of hAT elements by developing new tools for transposon mining and se...

The chromosomal DNA of the bacteria Streptomyces ambofaciens DSM40697 is an 8-Mb linear molecule that ends in terminal inverted repeats (TIRs) of 210 kb. The sequences of the TIRs are highly variable between the different linear replicons of Streptomyces (plasmids or chromosomes). Two spontaneous mutant strains harboring TIRs of 480 and 850 kb were isolated. The TIR polymorphism seen is a resul...

The Thermal Infrared Sensor (TIRS) requirements for noise, stability, and uniformity were designed to ensure the radiometric integrity of the data products. Since the launch of Landsat 8 in February 2013, many of these evaluations have been based on routine measurements of the onboard calibration sources, which include a variable-temperature blackbody and a deep space view port. The noise equiv...

We have identified in the human genome two families of mobile elements possessing the sequence characteristics of transposons that move directly from DNA to DNA rather than requiring the reverse transcription of an RNA intermediate. One type of element is closely related to the autonomous transposable element, mariner, and comprises a coding region for a transposase protein flanked by short ter...
