“…In this study, six of the proteins identified above were in the MVA pathway, but none was in the MEP pathway; therefore, replanting might promote the accumulation of terpenoids primarily via the MVA pathway. Furthermore, two unregulated proteins in replanted R. glutinosa were identified: momilactone A (MAS), which is a diterpenoid that might have been induced by a pathogen, and JA [48, 49], which has demonstrated potential allelopathic properties in rice [50]. …”

BackgroundThe normal growth of Rehmannia glutinosa, a widely used medicinal plant in China, is severely disturbed by replant disease. The formation of replant disease commonly involves interactions among plants, allelochemicals and microbes; however, these relationships remain largely unclear. As a result, no effective measures are currently available to treat replant disease.ResultsIn this study, an integrated R. glutinosa transcriptome was constructed, from which an R. glutinosa protein library was obtained. iTRAQ technology was then used to investigate changes in the proteins in replanted R. glutinosa roots, and the proteins that were expressed in response to replant disease were identified. An integrated R. glutinosa transcriptome from different developmental stages of replanted and normal-growth R. glutinosa produced 65,659 transcripts, which were accurately translated into 47,818 proteins. Using this resource, a set of 189 proteins was found to be significantly differentially expressed between normal-growth and replanted R. glutinosa. Of the proteins that were significantly upregulated in replanted R. glutinosa, most were related to metabolism, immune responses, ROS generation, programmed cell death, ER stress, and lignin synthesis.ConclusionsBy integrating these key events and the results of previous studies on replant disease formation, a new picture of the damaging mechanisms that cause replant disease stress emerged. Replant disease altered the metabolic balance of R. glutinosa, activated immune defence systems, increased levels of ROS and antioxidant enzymes, and initiated the processes of cell death and senescence in replanted R. glutinosa. Additionally, lignin deposition in R. glutinosa roots that was caused by replanting significantly inhibited tuberous root formation. These key processes provide important insights into the underlying mechanisms leading to the formation of replant disease and also for the subsequent development of new control measures to improve production and quality of replanted plants.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-017-1060-0) contains supplementary material, which is available to authorized users.

“…In the model moss Physcomitrella patens, UV-B irradiation is known to induce expression of the genes encoding chalcone synthases, which are biosynthetic enzymes leading to flavonoids, and flavonoid synthesis (Wolf et al, 2010). Production of momilactones A and B, which function as allelochemicals, are also induced by UV-C irradiation, elicitors, and JA in the moss Hypnum plumaeforme (Kato-Noguchi, 2011).…”

“…In addition, two unigenes annotated as momilactone-A synthase and six unigenes annotated as jacalin-related lectin proteins were exclusively expressed in these two tissues. Momilactone-A synthases and similar genes have been annotated among sequences from numerous plants, and their putative product momilactone, a defensive compound produced in response to elicitor signals, has only been recognized in a few plants to date 31 . Jacalin-related lectin proteins perform unidentified roles in plant immunity, defense, and response to biotic and abiotic stresses 32 .…”

Anthurium amnicola Dressler possesses a number of desirable and novel ornamental traits such as a purple-colored upright spathe, profuse flowering, and floral scent, some of which have been introgressed into modern Anthurium cultivars. As a first step in identifying genes associated with these traits, the transcriptome from root, leaf, spathe, and spadix from an accession of A. amnicola was assembled, resulting in 28,019 putative transcripts representing 19,458 unigenes. Genes involved in pigmentation, including those for the metabolism of chlorophyll and the biosynthesis of carotenoids, phenylpropanoids, and flavonoids were identified. The expression levels of one MYB transcription factor was highly correlated with naringenin 3-dioxygenase (F3H) and dihydroflavonol-4-reductase (DFR) in leaves, whereas a bHLH transcription factor was highly correlated with flavonoid 3′-monooxygenase (F3′H) and a DFR in spathes, suggesting that these two transcription factors might regulate flavonoid and anthocyanin synthesis in A. amnicola. Gene sequence and expression data from four major organs of A. amnicola provide novel basal information for understanding the genetic bases of ornamental traits and the determinants and evolution of form and function in the Araceae.Anthurium is a major cut flower and potted plant with a long and important history of breeding, selection, and cultivation in Hawaii. Today, the largest production comes from the Netherlands, with significant production and research in Hawaii and other tropical and subtropical areas. A popular attraction is its colorful spathe, a modified leaf that is associated with the spadix, an organ often also found in varied colors housing numerous bisexual, protogynous flowers. The major spathe color classes red, pink, orange, coral, and purple are from variations in anthocyanin type and levels and white coloration represents loss of pigment. Further, green coloration is thought to occur from variations in chlorophyll production, while brown coloration is likely derived from variations in anthocyanin and chlorophyll content [1][2][3][4][5] .The genus Anthurium consists of as many as 1,500 species found between Southern Mexico and Northern Argentina and is the largest genus in the Araceae family 6 . A limited sampling revealed that Anthurium species possess medium-sized genomes ranging from between 2 to 10 Gbp per haploid genome 7 . A majority of the modern Anthurium cultivars in the market today descend from historical or recent hybrids between species 8 particularly with A. andraeanum, which is characterized by the commercially popular heart-shaped spathe.
