Genome characterization of a Potato virus S (PVS) variant from tuber sprouts of Solanum phureja Juz. et Buk

RESUMEN Potato virus S (PVS) is a prevalent virus in potato fields in Colombia and the rest of the world. PVS has been classified into two separate lineages, PVS (Ordinary) and PVS (Andean), which are genetically distinct. In this study, the complete genome sequence of a new PVS isolate (PVS_Antioquia) was obtained using High-throughput sequencing (Illumina HiSeq-2000) from tuber sprouts of Sol...

Health-seeking habits play a critical role in early diagnosis and effective treatment for leprosy. The utilization of a health care system depends on socio-demographic factors, social structures, level of education, cultural beliefs and practices, gender discrimination, status of women, economic and political systems, environmental conditions, disease pattern and health care system itself. A cr...

Compatible Pollinations in Solanum chacoense Decrease Both S-RNase and S-RNase mRNA

Gametophytic self-incompatibility (GSI) allows plants to block fertilization by haploid pollen whose S-allele constitution matches one of the two S-alleles in the diploid styles. GSI in Solanum chacoense requires a stylar S-RNase, first secreted from cells of the transmitting tract then imported into incompatible (self) pollen tubes. However, the molecular mechanisms allowing compatible pollen ...

Stephenson et al.'s ecological fallacy

After more than a century of research the typical growth pattern of a tree was thought to be fairly well understood. Following germination height growth accelerates for some time, then increment peaks and the added height each year becomes less and less. The cross sectional area (basal area) of the tree follows a similar pattern, but the maximum basal area increment occurs at some time after th...
