Chick muscle cultures infected with wild-type Rous sarcoma virus form myotubes, but these myotubes vacuolate and by day 6 most have degenerated, leaving only large numbers of transformed mononucleated, replicating cells. Muscle cultures infected with a temperature-sensitive mutant (TS) at permissive temperatures behave as cells infected with wild-type Rous sarcoma virus. TS-infected cells reare...

Abstract Dahlia is an ornamental plant well adapted to open field cultivation and one of the crops in “Flowers for All” Project, a nation-wide extension project. High temperatures duration extreme heat waves are expected be more frequent next decades. Therefore, understanding determining high temperature that causes irreversible damage flowers interest preparing farmers mitigate adapt their cro...

l h e uvh6 mutant of Arabidopsis was previously isolated in a screen for increased sensitivity to ultraviolet (UV) radiation. uvh6 mutant plants were killed by incubation at 37°C for 4 d, a treatment not lethal to wild-type plants. Furthermore, under permissive conditions, uvh6 plants were yellow-green with an approximately onethird lower chlorophyll content. Cenetic analysis of the uvh6 mutant...

Bull trout (Salvelinus confluentus) were recently listed as threatened in the United States under the federal Endangered Species Act. Present and historical habitat of this species includes waterways that have been impacted by metals released from mining and mineral processing activities. We conducted paired bioassays with bull trout and rainbow trout (Oncorhynchus mykiss) to examine the relati...

Of 173 mutants of Saccharomyces cerevisiae resistant to the antimitotic drug benomyl (BenR), six also conferred cold-sensitivity for growth and three others conferred temperature-sensitivity for growth in the absence of benomyl. All of the benR mutations tested, including the nine conditional-lethal mutations, were shown to be in the same gene. This gene, TUB2, has previously been molecularly c...
