The core collection is a small subset that minimizes genetic redundancy while preserving the maximum diversity of entire population. Research on crucial for efficient management and utilization germplasm resources. In this paper, concept research progress its construction have briefly been summarized. Subsequently, some perspectives proposed in field near future. Four novel opinions presented, ...
The Mars Desert Research Station is a Mars analog research site located in the desert outside of Hanksville, Utah, U.S.A. Here we present a preliminary checklist of the vascular plant and lichen flora for the station, based on collections made primarily during a two-week simulated Mars mission in November, 2014. Additionally, we present notes on the endolithic chlorophytes and cyanobacteria, an...
Two million plant ESTs, from 20 different plant species, and totalling more than one 1000 Mbp of DNA sequence, represents a formidable transcriptomic resource. Sputnik uses the potential of this sequence resource to fill some of the information gap in the un-sequenced plant genomes and to serve as the foundation for in silicio comparative plant genomics. The complexity of the individual EST col...
Plant identification is an interesting and challenging research topic due to the variety of plant species. Among different part of the plant, leaf is widely used for plant identification because it is usually the most abundant type of data available in botanical reference collections and the easiest to obtain in the field studies. A number of works have been done for plant leaf identification. ...
This report summarizes the activities and outcomes of the second workshop of the US Culture Collection Network, formally an activity of the US National Science Foundation sponsored Research Coordination Network for a Community of ex situ Microbial Germplasm Repositories. The workshop included presentations on topics as diverse as permitting for genetically engineered plant pest organisms to fac...
Mosquito collections by using light traps have been carried out at 10 to 11 stations in Kyoto City area at intervals of about 10 days every year. Mean percent indexes (MPI), being calculated from the data of mosquito collections, were used for comparison of the annual abundance of mosquitoes. It is no doubt that Culex tritaeniorhynchus summorosus has decreased recently and this decrease is corr...
INTRODUCTION During the 1990s, the popularity of the genus Echinacea Moench (Asteraceae) as a dietary supplement in the United States increased markedly, as the general public learned of its possible efficacy in fighting colds and other illnesses (Bauer and Wagner 1991; Li 1998). Plant and medical scientists responded to this phenomenon by increasing their efforts to understand the biology, cul...
After a century of incremental research, technological advances, coupled with a need for sustainable crop yield increases, have reinvigorated the study of beneficial plant-microbe interactions with attention focused on how microbiomes alter plant phenotypes. We review recent advances in plant microbiome research, and describe potential applications for increasing crop productivity. The phylogen...
