“…The reason that pathogens and pests are a potential concern for perennial feedstock crops can be summarized by one word: monoculture. When little bluestem, prairie cordgrass, switchgrass, and most other feedstock species were found in their native ecosystem(s), there was usually some level of heterogeneity in terms of both species diversity and genetic uniformity within each species (Fu et al 2004;Kittelson and Handler 2006;Polley et al 2007). That is, individuals of one species were not usually the only plants within a given area, and if they were, it was common that multiple genetically unique individuals were present.…”

, J. M.; Owens, V.; Gedye, K.; and Boe, A., "A multiple species approach to biomass production from native herbaceous perennial feedstocks" (2009 Abstract Due to the rapid rate of worldwide consumption of nonrenewable fossil fuels, production of biofuels from cellulosic sources is receiving increased research emphasis. Here, we review the feasibility to produce lignocellulosic biomass on marginal lands that are not well-suited for conventional crop production. Large areas of these marginal lands are located in the central prairies of North America once dominated by tallgrass species. In this article, we review the existing literature, current work, and potential of two native species of the tallgrass prairie, prairie cordgrass (Spartina pectinata), and little bluestem (Schizachyrium scoparium) as candidates for commercial production of biofuel. Based on the existing literature, we discuss the need to accelerate research in the areas of agronomy, breeding, genetics, and potential pathogens. Cropping systems based on maintaining biodiversity across landscapes are essential for a sustainable production and to mitigate impact of pathogens and pests.

“…, Table ), and corolla tubes of dissimilar lengths often are associated with different pollinators (Boyd, ; Cohen, ). For example, flowers with long corolla tubes (> 25 mm in length) tend to be pollinated by hummingbirds or moths (Grant & Grant, ; Boyd, ; Cohen, ), whereas flowers with shorter corolla tubes (< 20 mm in length) are visited by bees and butterflies (Weller, ; Kittelson & Handler, ). Therefore, a change in the length of the corolla may be associated with a shift in the type of pollinator that visits the flower.…”

Continuous characters in phylogenetic analyses: patterns of corolla tube length evolution in LithospermumL. (Boraginaceae)

The present study comprises an analysis of six different scoring schemes and eight different types of analytic methods aiming to investigate the evolution of a continuous character (i.e. corolla tube length) in Lithospermum L. (Boraginaceae). Corolla tube length in the genus is quite variable, ranging from 1 mm to 75 mm, and the length of the corolla tube has implications for pollination biology, such as longer corolla tubes (> 25 mm in length) being pollinated by hummingbirds or moths. In general, the various methods resolve similar ancestral character states; however, different states are reconstructed at nodes in which the descendants greatly differ in corolla tube length. Additionally, it is suggested that all of the variation of a continuous character should be included in analyses, and this may necessitate multiple analyses with different partitions of the data. The various analyses provide evidence that two maximum parsimony methods, linear parsimony and the TNT method, minimize the number of different rates of evolution. In Lithospermum, six origins of corolla tubes > 20 mm in length are resolved, and these origins occurred at two different times periods: (1) in the shadow of hummingbird diversification in North America (approximately 6–8 Mya) and (2) more recently (approximately 1–1.5 MyA). Four substantial decreases in corolla tube length also are reconstructed, and these may be associated with the origin of self‐pollination. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, ••, ••–••.

Shikonin and its derivatives, isolated from traditional medicinal plant species of the genus Lithospermum, Alkanna, Arnebia, Anchusa, Onosma, and Echium belonging to the Boraginaceae family, have numerous applications in foods, cosmetics, and textiles. Shikonin, a potent bioactive red pigment, has been used in traditional medicinal systems to cure various ailments and is well known for its diverse pharmacological potential such as anticancer, antithrombotic, neuroprotective, antidiabetic, antiviral, anti-inflammatory, anti-gonadotropic, antioxidants, antimicrobial and insecticidal. Herein, updated research on the natural sources, pharmacology, toxicity studies, and various patents filed worldwide related to shikonin and approaches to shikonin’s biogenic and chemical synthesis are reviewed. Furthermore, recent studies to establish reliable production systems to meet market demand, functional identification, and future clinical development of shikonin and its derivatives against various diseases are presented.
