ABSTRACT: Crown transcriptome analysis of Norstar (NO), Manitou (MA), and the near-isogenic lines (NIL) spring Norstar (SN) and winter Manitou (WM) under field conditions
Project description:To explore transcriptional regulations in common wheat cultivars Norstar (NO), Manitou (MA), and the near-isogenic lines (NIL) spring Norstar (SN) and winter Manitou (WM) during seasonal cold acclimation.
Project description:To investigate the genetic relationship between two major grain length loci GS3 and qGL3, we developed the near-isogenic lines (NILs), NIL-GS3 (GS3/qGL3), NIL-qgl3 (gs3/qgl3), NIL-GS3/qgl3 (GS3/qgl3) in the background of 93-11 (gs3/qGL3) by crossing and MAS approach. Four samples was analyzed: three near-isogenic lines (NILs), NIL-GS3 (GS3/qGL3), NIL-qgl3 (gs3/qgl3), NIL-GS3/qgl3 (GS3/qgl3) and their background of 93-11. Every sample had three independed duplications. And the primary panicle with 3-6 cm length from the three NILs and 93-11 were used for RNA preparation and hybrid with Rice Genome OneArray Microarray (Phalanx Biotech Group).

Project description:Comparison of syncytia gene expression between soybean near-isogenic lines 7923R (NIL-R) and 7923S (NIL-S) infected with the soybean cyst nematode (PA3).
Project description:Gene expression profile of response to auxin at 3 h after treatment in rice root tips: IR64 (loss-of-function of DRO1 type) vs Near-isogenic line homozygous for the Kinandang Patong allele of DRO1 in an IR64 genetic background (Dro1-NIL; gain-of-function of DRO1 type) We used two rice varieties, IR64 and near-isogenic line homozygous for the Kinandang Patong allele of DRO1 in an IR64 genetic background (Dro1-NIL). We performed comprehensive microarray analysis of rice root tips with auxin treatment (3h) and pre-treatment (0h) in IR64 and Dro1-NIL. Seedling root tips of IR64 and Dro1-NIL were treated with 10 M-BM-5M 2,4-D. n = 3 biological repeats (15 seedlings per repeat).
Project description:The green rice leafhopper (GRH), Nephotettix cincticeps Uhler, is a major insect pest of cultivated rice in temperate Asia. GRH2-near-isogenic line (NIL) TGRH11, GRH4-NIL (TGRH16) and GRH2/GRH4-pyramided line (PYL) TGRH29 were developed by introducing the GRH2 and GRH4 from indica rice (DV85). We identified GRH-inducible genes in respective rice lines. Furthermore, we compared the gene expression levels between NILs/PYL and control plants (T65).
Project description:Microarray gene expression analysis were performed to identify genes responding to Fusarium graminearum inoculation and genes that show a differential regulation between the resistant c.v. Sumai-3 and the susceptible near isogenic lines. Sumai-3 is a Chinese wheat cultivar, the most commonly used source of resistance to Fusarium head blight (FHB) disease. NIL-3 and NIL-4 are near isogenic lines susceptible to FHB and are derived from a cross between Sumai-3 and Chuan980, a susceptible wheat cultivar, followed by seven generations of marker assisted backcrossing with the recurrent parent Sumai-3 and selection for FHB susceptibility in each generation by artificial inoculation with F. graminearum. A combination of DNA markers including simple sequence repeats (SSRs) and amplified fragment length polymorphisms (AFLPs) were used to screen for DNA polymorphisms between Sumai-3 and its susceptible NILs. Polymorphic markers were mapped using a mapping population. The analysis indicated 7 polymorphisms between the susceptible NILs and the resistant Sumai-3. The analysis indicated that NIL-3 differs from Sumai-3 at chromosome 3BS and NIL-4 differs from Sumai-3 at chromosome 2AL region.

Project description:Identify genes underlying the Fusarium crown rot resistance locus and find out if expressed genes associated with resistance to Fusarium crown rot were related to those observed by others for Fusarium head blight.
