A plant＇s ability to maintain or improve its yield under limiting conditions,such as nutrient de ficiency or drought,can be strongly in fluenced by root system architecture（RSA）,the three-dimensional distribution of the different root types in the soil. The ability to image,track and quantify these root system attributes in a dynamic fashion is a useful tool in assessing desirable genetic and physiological root traits. Recent advances in imaging technology and phenotyping software have resulted in substantive progress in describing and quantifying RSA. we have designed a hydroponic growth system which retains the three-dimensional RSA of the plant root system,while allowing for aeration,solution replenishment and the imposition of nutrient treatments,as well as high-quality imaging of the root system. The simplicity and flexibility of the system allows for modi fications tailored to the RSA of different crop species and improved throughput. This paper details the recent improvements and innovations in our root growth and imaging system which allows for greater image sensitivity（detection of fine roots and other root details）,higher ef ficiency,and a broad array of growing conditions for plants that more closely mimic those found under field conditions.

Genomics and introgression： Discovery and mapping of thousands of species-diagnostic SNPs using RAD sequencing

Invasive hybridization and introgression pose a serious threat to the persistence of many native species. Understand- ing the effects of hybridization on native populations （e.g., fitness consequences） requires numerous species-diagnostic loci dis- tributed genome-wide. Here we used RAD sequencing to discover thousands of single-nucleotide polymorphisms （SNPs） that are diagnostic between rainbow trout （RBT, Oncorhynchus mykiss）, the world＇s most widely introduced fish, and native westslope cutthroat trout （wCT, （9. clarkii lewisi） in the northern Rocky Mountains, USA. we advanced previous work that identified 4,914 species-diagnostic loci by using longer sequence reads （100 bp vs. 60 bp） and a larger set of individuals （n = 84）. we sequenced RAD libraries for individuals from diverse sampling sources, including native populations of wCT and hatchery broodstocks of wCT and RBT. we also took advantage of a newly released reference genome assembly for RBT to align our RAD loci. In total, we discovered 16,788 putatively diagnostic SNPs, 10,267 of which we mapped to anchored chromosome locations on the RBT genome. A small portion of previously discovered putative diagnostic loci （325 of 4,914） were no longer diagnostic （i.e., fixed between species） based on our wider survey of non-hybridized RBT and wCT individuals. Our study suggests that RAD loci mapped to a draft genome assembly could provide the marker density required to identify genes and chromosomal regions in- fluencing selection in admixed populations of conservation concern and evolutionary interest [Current Zoology 61 （1）： 146-154, 2015].
