"This study along with associated microarray experiments are the initial steps in a coordinated effort by the Daphnia Genomics Consortium to build the necessary genomic platform needed to discover genes that account for the phenotypic diversity within the genus and to gain new insights into crustacean biology. This effort will soon include the first crustacean genome sequence. "

EcoTILLING for the identification of allelic variants of melon eIF4E, a factor that controls virus susceptibility

crackpot submitted, created time 1 year 6 months (www.biomedcentral.com)

"This study shows the applicability of EcoTILLING in Cucumis spp., but given the conservation of eIF4E, new candidate genes should probably be considered to identify new sources of resistance to plant viruses. Part of the methodology described here could alternatively be used in TILLING experiments that serve to generate new eIF4E alleles."

Distinct class of putative "non-conserved" promoters in humans: Comparative studies of alternative promoters of human and mouse genes

DanyC submitted, created time 1 year 6 months (www.genome.org)

"Although recent studies have revealed that the majority of human genes are subject to regulation of alternative promoters, the biological relevance of this phenomenon remains unclear. Researchers have also demonstrated that roughly half of the human RefSeq genes examined contain putative alternative promoters (PAPs). Here they report large-scale comparative studies of PAPs between human and mouse counterpart genes

Speaking like a Chinese native is in the genes

captainclaw submitted, created time 1 year 7 months (www.newscientist.com)

Enquire in Chinese after the health of someone's mother and you could well receive an answer about the well-being of their horse. Subtle pronunciation differences in tonal languages such as Chinese change the meaning of words, which is one reason why they are so hard for speakers of non-tonal languages like English to learn.Babies of all backgrounds can grow up speaking any language, so there is no such thing as "a gene for Chinese". There may, however, be something in our genes that affects how easily we can learn certain languages

Resistance Genes In Our Food Supply

addict submitted, created time 1 year 7 months (www.medicalnewstoday.com)

Could the food we eat be contributing to the continuing rise of antibiotic-resistant infections? Harmless and even beneficial bacteria that exist in our food supply may also be carrying genes that code for antibiotic resistance. Once in our bodies, could they transmit the resistance genes to disease-causing bacteria? The data indicate that food could be an important avenue for antibiotic-resistant bacterial evolution and dissemination. The role of commensals, especially food-borne microbes, in transmitting resistance genes are becoming a concern to the scientific community.
