Pandemi Covid-19 telah berdampak pada pemerintah Kota Kediri yang memberlakukan kebijakan pembatasan kegiatan aktivitas masyarakat guna menekan angka penyebaran Covid-19. Dampak menimbulkan perubahan di berbagai aspek seperti kepadatan lalu lintas, interaksi sosial, dan operasional tempat umum masyarakat. Tujuan penelitian ini adalah untuk menganalisis suhu permukaan lahan saat sebelum sesudah ...

Mutations in a number of genes responsible for the maintenance of transposon silencing have been reported. However, the initiation of epigenetic silencing of transposable elements is poorly characterized. Here, we report the identification of a single dominant locus, Mu killer (Muk), that acts to silence MuDR, the autonomous regulatory transposon of the Mutator family of transposable elements i...

The Arabidopsis mutants far1 and fhy3 display a phenotype of reduced inhibition of hypocotyl elongation, which is specific to far-red light and therefore specific to the phytochrome A (phyA)-signaling pathway. We report that the proteins encoded by the FAR1 and FHY3 genes are both related to the transposases of type II MuDR family transposons. We demonstrate that the FAR1 protein is capable of ...

The widespread use of the maize Mutator (Mu) system to generate mutants exploits the preference of Mu transposons to insert into genic regions. However, little is known about the specificity of Mu insertions within genes. Analysis of 79 independently isolated Mu-induced alleles at the gl8 locus established that at least 75 contain Mu insertions. Analysis of the terminal inverted repeats (TIRs) ...

The Global Change Unit (GCU) at the University of Valencia has been involved in several calibration/validation (cal/val) activities carried out in dedicated field campaigns organized by ESA and other organisms. However, permanent stations are required in order to ensure a long-term and continuous calibration of on-orbit sensors. In the framework of the CEOS-Spain project, the GCU has managed th...

MITEs (miniature inverted-repeated transposable elements) are a particular class of defective DNA transposons usually present within genomes as high copy number populations of highly homogeneous elements. Although an active MITE, the mPing element, has recently been characterized in rice, the transposition mechanism of MITEs remains unknown. It has been proposed that transposases of related tra...

1. ALBANIA The Republic of Albania, located in the western part of the Balkan Peninsula; is bounded in the northwest and north by Serbia and Montenegro, in the east by FYROM, in the southeast and south by Greece, and in the west by the Adriatic Sea. Albania is divided into 26 districts. Albania is predominantly mountainous. Lowlands, which comprise less than one-quarter of the land area, are li...

Maize MuDR/Mu elements are one of the most active Class II transposons and are widely used for transposon tagging for gene cloning. The autonomous MuDR encodes a transposase, while diverse non-autonomous elements share similarity to MuDR only within their ~215 bp terminal inverted repeats (TIRs). Four independent Mu-induced mutable alleles of the anthocyanin pigment pathway Bronze2 (Bz2) locus ...

Transposable elements (TEs) have a major impact on genome evolution, but they are potentially deleterious, and most of them are silenced by epigenetic mechanisms, such as DNA methylation. Here, we report the characterization of a TE encoding an activity to counteract epigenetic silencing by the host. In Arabidopsis thaliana, we identified a mobile copy of the Mutator-like element (MULE) with de...

This paper reviews the development of in-orbit radiometric calibration methods in the past 40 years. It summarizes the development of in-orbit radiometric calibration technology of typical satellite sensors in the visible/near-infrared bands and the thermal infrared band. Focuses on the visible/near-infrared bands radiometric calibration method including: Lamp calibration and solar radiationbas...
