Project description:Biologists have long been fascinated by the amazing diversity of animal colour patterns. Despite
much interest, the underlying evolutionary and developmental mechanisms contributing to
their rich variety remain largely unknown, especially the vivid and complex colour patterns seen
in vertebrates. The model [1] shows, that complex and camouflaged animal markings can be formed
by the ‘blending’ of simple colour patterns. A mathematical model predicts that crossing
between animals having inverted spot patterns (for example, ‘light spots on a dark background’
and ‘ dark spots on a light background’ ) will necessarily result in hybrid offspring that have
camouflaged labyrinthine patterns as ‘ blended ’ intermediate phenotypes. In [1] the authors
confirmed the broad applicability of the model prediction by empirical examination of natural and
artificial hybrids of salmonid fish. The results suggest an unexplored evolutionary process by means of
‘pattern blending’, as one of the possible mechanisms underlying colour pattern diversity and
hybrid speciation. The model file is in MorpheusML format and can be opened in the free, open-source multicellular modeling software
Morpheus (https://morpheus.gitlab.io) to simulate the time course (movie) of the spatio-temporal dynamics.
It resembles figure 3a from [1], where a 2D parameter space shows the transition from black to white spots
through intermediate labyrinthine patterns.

Project description:Unripening mutant was identified from natural population of cv. Arka Vikas and the mutant was characterized with un ripened with light yellowish colour pericarp. Differential gene expression studies were carried out between unripening mutant and wild type using the whole genome microarray expression profiling as a discovery platform. Tomato fruit tissue samples from different stages of fruit ripening like Mature green, Breaker, Turning and Ripening stages of unripening mutant and wild type was used for microarray gene expression analysis. Carotenoid pathway analysis of both mutant and wild type reveals genes involved in the pathway altered in the unripening mutant. Four genes (PSY, PDS, CRTISO, CYCB) of the carotenoid pathway was quantified in the same RNA samples by real-time PCR, confirming that the variation of the gene expression in unripening mutant.

Project description:Deep sequencing of total RNA extracted from the genital discs of males for each of the following strains : Drosophila sechellia, Drosophila mauritiana, hybrid introgression line 3Q1(A) and hybrid introgression line Q1(A) Analysis of poly(A)+ RNA for three independent biological replicates of sequencing libraries for each of the following strains: D. sechellia w, D. mauritiana P-insertion Q1, hybrid introgression line 3Q1(A), and hybrid introgression line Q1(A). Male genital discs were obtained as described above, and total RNA was extracted using RNAqueousM-CM-^BM-BM-.-Micro Kit (Ambion). Poly(A)+ transcripts were isolated subsequently using MicroPoly(A)PuristM-CM-"M-BM-^DM-BM-" Kit (Ambion). To facilitate normalization of reads across our samples, at this stage of library construction we spiked-in small amounts of exogenous RNA from ArrayControlM-CM-"M-BM-^DM-BM-" Kit (Ambion) into each sample of poly(A)+ RNA. Paired-end sequencing was carried out by loading the samples onto four lanes (three samples per lane) of a flow cell and run on an Illumina Genome Analyzer IIx sequencer using 72 cycles per end of each paired-end read. Biological replicates of each genotype were loaded onto separate lanes.

Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.
