Using the resource-based view of the firm, the authors hypothesize that differences in adoption of radical technologies among firms can be attributed to a sense-and-respond capability of firms with respect to new technologies, which is termed technological opportunism. Using survey data from senior managers in business-to-business firms, the authors study the adoption of e-business, a radical technology with the potential to alter business models. The authors first establish the distinctiveness of technological opportunism from related constructs, such as organizational innovativeness, and show that it offers a significantly better explanation of technology adoption than existing constructs do. In a follow-up survey of senior managers, the authors investigate the antecedents of technological opportunism and find that organizations can develop technological opportunism by taking specific actions such as focusing on the future, by having top management advocate new technologies, and by becoming more of an adhocracy culture and less of a hierarchy culture. The proposed technological opportunism construct can inform theory development on the relative emphasis on internal (research and development) versus external (buying, licensing) development of technologies and the complementarities in technology orientation and market orientation in the firm. The results can be used by managers who seek to develop the technological opportunism capability of their firms and by those in technology vendor firms who seek to develop segmentation strategies based on the technological opportunism capabilities of their customer firms.

Marketing executives are being urged to speak in the language of finance to gain internal support for marketing initiatives. Responding to this call, the authors examine the impact of a firm's advertising and its research and development (R&D) on the systematic risk of its stock, a key metric for publicly listed firms. They hypothesize that a firm's advertising and R&D expenditures create intangible assets that insulate it from stock market changes, lowering its systematic risk. They test the hypotheses using a panel data on 644 publicly listed firms between 1979 and 2001, consisting of five-year moving windows. They scale the firm's advertising and R&D expenditures by its sales. After controlling for factors that accounting and finance researchers have shown to be associated with systematic risk, the authors find that advertising/sales and R&D/sales lower a firm's systematic risk. The article's findings extend prior research that has focused primarily on the effect of marketing initiatives on performance metrics without consideration of systematic risk. For practice, the ability of advertising and R&D to reduce systematic risk highlights the multifaceted implications of advertising and research programs. The article's findings may surprise senior management, some of whom are skeptical of the financial accountability of advertising programs.

Chickpea (Cicer arietinum L.) is an important legume crop in the semi-arid regions of Asia and Africa. Gains in crop productivity have been low however, particularly because of biotic and abiotic stresses. To help enhance crop productivity using molecular breeding techniques, next generation sequencing technologies such as Roche/454 and Illumina/Solexa were used to determine the sequence of most gene transcripts and to identify drought-responsive genes and gene-based molecular markers. A total of 103 215 tentative unique sequences (TUSs) have been produced from 435 018 Roche/454 reads and 21 491 Sanger expressed sequence tags (ESTs). Putative functions were determined for 49 437 (47.8%) of the TUSs, and gene ontology assignments were determined for 20 634 (41.7%) of the TUSs. Comparison of the chickpea TUSs with the Medicago truncatula genome assembly (Mt 3.5.1 build) resulted in 42 141 aligned TUSs with putative gene structures (including 39 281 predicted intron/splice junctions). Alignment of ∼37 million Illumina/Solexa tags generated from drought-challenged root tissues of two chickpea genotypes against the TUSs identified 44 639 differentially expressed TUSs. The TUSs were also used to identify a diverse set of markers, including 728 simple sequence repeats (SSRs), 495 single nucleotide polymorphisms (SNPs), 387 conserved orthologous sequence (COS) markers, and 2088 intron-spanning region (ISR) markers. This resource will be useful for basic and applied research for genome analysis and crop improvement in chickpea.

BackgroundChickpea (Cicer arietinum L.), an important grain legume crop of the world is seriously challenged by terminal drought and salinity stresses. However, very limited number of molecular markers and candidate genes are available for undertaking molecular breeding in chickpea to tackle these stresses. This study reports generation and analysis of comprehensive resource of drought- and salinity-responsive expressed sequence tags (ESTs) and gene-based markers.ResultsA total of 20,162 (18,435 high quality) drought- and salinity- responsive ESTs were generated from ten different root tissue cDNA libraries of chickpea. Sequence editing, clustering and assembly analysis resulted in 6,404 unigenes (1,590 contigs and 4,814 singletons). Functional annotation of unigenes based on BLASTX analysis showed that 46.3% (2,965) had significant similarity (≤1E-05) to sequences in the non-redundant UniProt database. BLASTN analysis of unique sequences with ESTs of four legume species (Medicago, Lotus, soybean and groundnut) and three model plant species (rice, Arabidopsis and poplar) provided insights on conserved genes across legumes as well as novel transcripts for chickpea. Of 2,965 (46.3%) significant unigenes, only 2,071 (32.3%) unigenes could be functionally categorised according to Gene Ontology (GO) descriptions. A total of 2,029 sequences containing 3,728 simple sequence repeats (SSRs) were identified and 177 new EST-SSR markers were developed. Experimental validation of a set of 77 SSR markers on 24 genotypes revealed 230 alleles with an average of 4.6 alleles per marker and average polymorphism information content (PIC) value of 0.43. Besides SSR markers, 21,405 high confidence single nucleotide polymorphisms (SNPs) in 742 contigs (with ≥ 5 ESTs) were also identified. Recognition sites for restriction enzymes were identified for 7,884 SNPs in 240 contigs. Hierarchical clustering of 105 selected contigs provided clues about stress- responsive candidate genes and their expression profile showed predominance in specific stress-challenged libraries.ConclusionGenerated set of chickpea ESTs serves as a resource of high quality transcripts for gene discovery and development of functional markers associated with abiotic stress tolerance that will be helpful to facilitate chickpea breeding. Mapping of gene-based markers in chickpea will also add more anchoring points to align genomes of chickpea and other legume species.
