tetragonia vestita/アデノシン

In the mature phloem of Tetragonia expansa strong ATPase activity is present on the plasmalemma of the companion cells and sieve tubes, and probably on the ER of the latter. The sieve tube wall sometimes shows a lead deposit. When the tissues is pre-treated with DNP there is often a diffuse deposit

The positive-sense RNA genome of beet yellows closterovirus (BYV) encompasses open reading frames (ORFs) for the viral capsid protein (CP, ORF 6) and for a CP homologue (p24, ORF 5). The sequences of the ORFs 5 and 6 were inserted into an Escherichia coli expression vector, pQE-9, under the control

ABSTRACT The first reported U.S. isolate of Beet black scorch necrovirus (BBSV) was obtained and characterized. Host range of the virus for localized and occasionally systemic infection included the Chenopodiaceae and Tetragonia expansa; Nicotiana benthamiana supported symptomless systemic infection
