DISTRIBUTION OF A TY3/GYPSY-LIKE RETROELEMENT ON THE A AND B-CHROMOSOMES OF CESTRUM STRIGILATUM RUIZ & PAV. AND CESTRUM INTERMEDIUM SENDTN. (SOLANACEAE)

Retroelements are a diversified fraction of eukaryotic genomes, with the Ty1/copia and Ty3/gypsy groups being very common in a large number of plant genomes.We isolated an internal segment of the Ty3/gypsy retroelement of Cestrum strigilatum (Solanaceae) using PCR amplification with degenerate primers for boneflesh d2 a conserved region of reverse

The last decade has seen accumulating evidence of various proteins being degraded by the core 20S proteasome, without its regulatory particle(s).Here, we will describe recent advances in our knowledge of the functional aspects of the 20S proteasome, exploring several different systems and processes.These include neuronal communication, post-transla

ABSTRACT Coronavirus (CoV) replication and transcription are carried out in close proximity to restructured endoplasmic reticulum (ER) membranes in replication/transcription complexes (RTC).Many of the CoV nonstructural proteins (nsps) are required for RTC function; however, not all of their functions are known.nsp15 contains an endoribonuclease do
