Transcriptome analysis of shade avoidance and shade tolerance in conifers

Main conclusionGymnosperms respond differently to light intensity and R:FR; although some aspects of shade response appear conserved, yet underlying mechanisms seem to be diverse in gymnosperms as compared to angiosperms.Shade avoidance syndrome (SAS) is well-characterized in the shade intolerant model species Arabidopsis thaliana whereas much less is known about shade tolerance...

The steps from sexual reproduction to apomixis

Main conclusionIn this paper, an interaction model of apomixis-related genes was constructed to analyze the emergence of apomictic types. It is speculated that apomixis technology will be first implemented in gramineous plants.Apomixis (asexual seed formation) is a phenomenon in which a plant bypasses the most fundamental aspects of sexual reproduction—meiosis and fertilization...

Genetic diversity for nitrogen use efficiency in Arabidopsis thaliana

Main conclusionThe plasticity of plant growth response to differing nitrate availability renders the identification of biomarkers difficult, but allows access to genetic factors as tools to modulate root systems to a wide range of soil conditions. Nitrogen availability is a major determinant of crop yield. While the application of fertiliser substantially increases the yield on...

Allopolyploidization facilitates gene flow and speciation among corn, Zea perennis and Tripsacum dactyloides

Main conclusionTripsacum dactyloides is closely related to Zea mays since Zea perennis and the MTP tri- species hybrid have four possible reproductive modes.Eastern gamagrass (Tripsacum dactyloides L.) and tetraploid perennial teosinte (Zea perennis) are well known to possess genes conferring resistance against biotic and abiotic stresses as well as adaptation to flood and...

Structural, physiological and genetic diversification of Silene vulgaris ecotypes from heavy metal-contaminated areas and their synchronous in vitro cultivation

Main conclusion Results provide significant comparison of leaf anatomy, pigment content, antioxidant response and phenolic profile between individuals from miscellaneous populations and describe unified cultivation protocols for further research on stress biology. The plant communities growing on heavy metal-polluted areas have attracted considerable attention due to their unique...

In vitro tissue culture of apple and other Malus species: recent advances and applications

Main conclusionStudies on the tissue culture of apple have allowed for molecular, biotechnological and applied breeding research to advance. In the past 8 years, over 100 papers advancing basic biology, genetic transformation and cryobiology have emerged.Apple (Malus × domestica Borkh.; Rosaceae) is an important fruit crop grown mainly in temperate regions of the world. In vitro...

Grass pea (Lathyrus sativus L.): orphan crop, nutraceutical or just plain food?

Main conclusionAlthough grass pea is an environmentally successful robust legume with major traits of interest for food and nutrition security, the genetic potential of this orphan crop has long been neglected.Grass pea (Lathyrus sativus L.) is a Neolithic plant that has survived millennia of cultivation and has spread over three continents. It is a robust legume crop that is...

Irrigation affects characteristics of narrow-leaved lupin (Lupinus angustifolius L.) seeds

Main conclusionWhile plant irrigation usually increases yield, irrigation also affects seed characteristics with respect to endoreplication level, chemical composition, number of carbonyl bands, and cuticular wax profiles.Seeds of sweet varieties of the narrow-leaved lupin have good nutritional properties; however, these plants are sensitive to water deficit. Irrigation improves...

Occurrence of brassinosteroids and influence of 24-epibrassinolide with brassinazole on their content in the leaves and roots of Hordeum vulgare L. cv. Golden Promise

Main conclusion24-epibrassinolide overcame the inhibitory effect of brassinazole on the barley growth and the content of brassinosteroids. The present work demonstrates the occurrence of mainly castasterone, brassinolide and cathasterone and lower amounts of 24-epibrassinolide, 24-epicastasterone, 28-homobrassinolide, typhasterol, 6-deoxocastasterone and 6-deoxotyphasterol in 14...

Mining the natural genetic variation in Arabidopsis thaliana for adaptation to sequential abiotic and biotic stresses

Main conclusionIn this genome-wide association study, we obtained novel insights into the genetic basis of the effect of herbivory or drought stress on the level of resistance against the fungus Botrytis cinerea.In nature, plants function in complex environments where they encounter different biotic and abiotic stresses individually, sequentially or simultaneously. The adaptive...

Involvement of ethylene biosynthesis and perception during germination of dormant Avena fatua L. caryopses induced by KAR1 or GA3

Main conclusionGermination of primary dormant wild oat caused by KAR1 or GA3 is associated with ACC accumulation and increased ethylene production shortly before radicle protrusion as a result of the non-transcriptional and transcriptional activation of ACS and ACO enzymes, respectively. Response to both compounds involves the modulation of ethylene sensitivity through ethylene...

Evolutionary and functional analyses of the 2-oxoglutarate-dependent dioxygenase genes involved in the flavonoid biosynthesis pathway in tobacco

Main conclusion This study illustrates the differences in the gene structure of 2-oxoglutarate-dependent oxygenase involved in flavonoid biosynthesis (2ODD-IFB), and their potential roles in regulating tobacco flavonoid biosynthesis and plant growth. Flavonol synthase (FLS), anthocyanidin synthase (ANS), and flavanone 3β-hydroxylase belong to the 2-oxoglutarate-dependent (2ODD...

De novo sequencing of the Lavandula angustifolia genome reveals highly duplicated and optimized features for essential oil production

Main conclusion The first draft genome for a member of the genus Lavandula is described. This 870 Mbp genome assembly is composed of over 688 Mbp of non-gap sequences comprising 62,141 protein-coding genes. Lavenders (Lavandula: Lamiaceae) are economically important plants widely grown around the world for their essential oils (EOs), which contribute to the cosmetic, personal...

Classification of fruit trichomes in cucumber and effects of plant hormones on type II fruit trichome development

The fruit trichomes or fruit spines of cucumber, Cucumis sativus L., are highly specialized structures originating from epidermal cells with diverse morphology, which grow perpendicular to the fruit surface. To understand the underlying molecular mechanisms of fruit trichome development, in this study, we conducted morphological characterization and classification of cucumber...

Magnetic sensitivity mediated by the Arabidopsis blue-light receptor cryptochrome occurs during flavin reoxidation in the dark

Cryptochromes are highly conserved blue-light-absorbing flavoproteins which have been linked to the perception of electromagnetic stimuli in numerous organisms. These include sensing the direction of the earth’s magnetic field in migratory birds and the intensity of magnetic fields in insects and plants. When exposed to light, cryptochromes undergo flavin reduction/reoxidation...

Main conclusion LAESI-MSI, an innovative high-throughput technique holds a unique potential for untargeted detection, profiling and spatial localization of metabolites from intact plant samples without need for extraction or extensive sample preparation. Our understanding of chemical diversity in biological samples has greatly improved through recent advances in mass spectrometry...

Unique chromoplast organisation and carotenoid gene expression in carotenoid-rich carrot callus

Main conclusionThe new model orange callus line, similar to carrot root, was rich in carotenoids due to altered expression of some carotenogenesis-associated genes and possessed unique diversity of chromoplast ultrastructure.Callus induced from carrot root segments cultured in vitro is usually pale yellow (p-y) and poor in carotenoids. A unique, non-engineered callus line of dark...
