While you may not gulp spinach by the can-fuls, if you love spanakopita or your go-to appetizer is spinach artichoke dip, then you'll be excited to know that new research out of Boyce Thompson Institute (BTI) will make it even easier to improve this nutritious and delicious, leafy green. Today in Nature Communications, researchers from BTI and the Shanghai Normal University report a new draft genome of Spinacia oleracea, better known as spinach. Additionally, the authors have sequenced the transcriptomes (all the RNA) of 120 cultivated and wild spinach plants, which has allowed them to identify which genetic changes have occurred due to domestication. "The spinach genome sequence and transcriptome variants developed in this study provide a wealth of valuable information that can be used to breed spinach with better disease-resistance, higher yield and better quality," asserted Zhangjun Fei, the project's lead researcher from BTI. Spinach, which is native to central Asia, is now cultivated worldwide, with a reported annual production of 24.3 million tons in 2014. Since it was first domesticated, gardeners and breeders have improved many agronomically important traits, such as leaf quality and nutrition, and over time these improvements have re-shaped the spinach genome. In turn, breeders today can use genomic information to speed up improvements, which is especially important for combatting significant diseases, like downy mildew. Known as the 'late blight' of spinach, the downy mildew disease has devastated crops throughout California, and has recently popped up in Upstate New York. Armed with a better understanding of the spinach genome, the researchers have identified several genes that may confer resistance to the downy mildew pathogen. Once identified in a resistant variety of spinach, such genes could be quickly transferred to other, possibly more nutritious varieties, boosting their immune systems to fight this disease while still maintaining marketable traits. Of particular interest to the researchers is the discovery that the genomes of cultivated spinach varieties are not too different from their wild progenitors. When a plant is domesticated, its genome will evolve over centuries of selection. In many cases, it gets forced through a bottleneck of genetic changes necessary for cultivation, creating a very different plant from that which was first brought out of the wild. A great example is the comparison of maize (corn) to its ancestor, teosinte. "By analyzing transcriptome variants of a large collection of cultivated and wild spinach accessions, we found that unlike other vegetable crops such as tomato and cucumber, spinach has a weak domestication bottleneck," explained first author, Chen Jiao. This was great news because it means there is still much room for spinach improvement, but it also made it tougher to pinpoint genomic markers that could speed up the breeding process. Nonetheless, the team identified many regions in the genome directly attributable to the domestication process, that could be possibly linked to valuable traits, such as bolting, leaf number, and stem length When asked for her favorite spinach recipe, first author Chen Jiao replied, "I usually make spinach salad for my family twice a week. It is very nutritious and easy to make. I just throw a handful of baby spinach, some croutons and fried bacon, and boiled eggs in a bowl and then drizzle all with bottled dressing." So the next time you eat a luscious, green spinach salad, thank a scientist for keeping you healthy and strong! Explore further: Dole recalls some spinach after salmonella found in sample

Ordered mesoporous inorganic non-oxide materials attract increasing interest due to their plenty of unique properties and functionalities and potential applications. Lots of achievements have been made on their synthesis and structural characterization, especially in the last five years. In this critical review, the ordered mesoporous non-oxide materials are categorized by compositions, including non-oxide ceramics, metal chalcogenides, metal nitrides, carbides and fluorides, and systematically summarized on the basis of their synthesis approaches and mechanisms, as well as properties. Two synthesis routes such as hardlating (nanocasting) and softlating (surfactant assembly) routes are demonstrated. The principal issues in the nanocasting synthesis including the template composition and mesostructure, pore surface chemistry, precursor selection, processing and template removal are emphatically described. A great number of successful cases from the softlating method are focused on the surfactant liquid-crystal mesophases to synthesize mesostructured metal chalcogenide composites and the inorganic-block-organic copolymer self-assembly to obtain non-oxide ceramics (296 references). © 2011 The Royal Society of Chemistry.

The interactions between polyphenols, especially flavonoids and plasma proteins, have attracted great interest among researchers. Few papers, however, have focused on the structure-affinity relationship of polyphenols on their affinities for plasma proteins. The aim of this review is to give an overview of the research reports on the characterization, influence on the bioactivity, and the structure-affinity relationship for studying the affinities between polyphenols and plasma proteins. The molecular properties that influence the affinities of polyphenols for plasma proteins are the following: 1) One or more hydroxyl groups in the B-ring (e.g., 3',4' dihydroxylated B ring catechol group) of flavonoids enhanced the binding affinities to proteins. However, the hydroxyl group in the C-ring will weaken the binding interaction. 2) The presence of an unsaturated 2,3-bond in conjugation with a 4-carbonyl group, characteristic of flavonols structure, has been associated with stronger binding affinity with plasma proteins; 3) The glycosylation of flavonoids decreases the affinities for plasma proteins by 1-3 orders of magnitude depending on the conjugation site and the class of sugar moiety; 4) The methylation of hydroxyl groups in flavonoids slightly enhanced the affinities for plasma proteins by 2-16 times; 5) The galloylated catechins have higher binding affinities for plasma proteins than do non-galloylated catechins and the pyrogallol-type catechins have higher affinities than do the catechol-type catechins. The affinity of the catechin with 2,3-trans structure was lower than those of the catechin with 2,3-cis structure; 6) The gallotannins with more gallol groups presented a much higher percentage of binding to plasma proteins. α-D-Gallotannin showed a greater affinity for plasma proteins than does the natural stereoisomer, β-D-gallotannin; 7) The binding degree of chlorogenic acid with only one caffeoyl group was lower than the binding degrees of caffeoyl quinic acids with more caffeoyl groups. The methylation of phenolic acid decreased the affinity for BSA. © Taylor and Francis Group, LLC.

In the study of the perturbation of Hamiltonian systems, the first order Melnikov functions play an important role. By finding its zeros, we can find limit cycles. By analyzing its analytical property, we can find its zeros. The main purpose of this article is to summarize some methods to find its zeros near a Hamiltonian value corresponding to an elementary center, nilpotent center or a homoclinic or heteroclinic loop with hyperbolic saddles or nilpotent critical points through the asymptotic expansions of the Melnikov function at these values. We present a series of results on the limit cycle bifurcation by using the first coefficients of the asymptotic expansions. © 2012 World Scientific Publishing Company.

By integrating the metallic metamaterials (MMs) with a graphene layer, the resonant properties of an active tunable device based on the metal-SiO2-graphene (MSiO2G) structure have been theoretically investigated in the near-IR spectral region. The results manifest that the influences of the graphene layer on the propagation properties are significant. Owing to the tunability of the Fermi level of graphene, the resonance of transmitted or reflected curves can be tuned in a wide range (160-193 THz). To an original metal unit cell structure, an elevated Fermi level of graphene layer enhances the resonance dips and shifts it to the higher frequency. Compared with the original structure, the corresponding complementary MMs structure shows a much sharper spectral curve and can be used to fabricate a switcher or filters. The results are very helpful for designing graphene plasmonic devices. © 2015 Optical Society of America.

The organometallic approach is one of the most active topics in catalysis. The application of NH functionality in organometallic catalysis has become an important and attractive concept in catalyst design. NH moieties in the modifiers of organometallic catalysts have been shown to have various beneficial functions in catalysis by molecular recognition through hydrogen bonding to give catalyst-substrate, ligand-ligand, ligand-catalyst, and catalyst-catalyst interactions. This Review summarizes recent progress in the development of the organometallic catalysts based on the concept of cooperative catalysis by focusing on the NH moiety. The "magic" effects of N-H moieties in organometallic catalysis have been observed in various reaction systems. Recent advances are presented in the development of organometallic catalysts based on the concept of cooperative catalysis by taking the beneficial effect of the NH moiety in the catalyst by catalyst-substrate, ligand-ligand, and catalyst-catalyst interactions.

Using graphene metamaterial (MM) patterns, the tunable resonant properties of graphene- SiO2/Si (GSiO2Si) structures deposited on flexible polymer substrates have been theoretically investigated in the terahertz regime. This study shows that the tuning mechanism of the GSiO2Si structure mainly depends on dipolar resonance, which is different from the conventional metallic MM structure based on the LC resonance. For graphene MM structures, the resonant transmission curves can be tuned over a wide range by controlling applied electric fields. The modulation depth of transmission is about 80%. As the Fermi level of the graphene layer increases, the resonant transmission become stronger, and the resonant dips significantly shift to higher frequency.

Music and language share similar properties and are processed in overlapping brain regions. As a common information-bearing element in music and language, pitch plays an essential role in encoding musical melodies, signifying linguistic functions, and conveying emotions through music and speech. However, two distinct neurodevelopmental disorders, congenital amusia (CA) and autism spectrum disorders (ASD), affecting millions of people in Europe and worldwide, may selectively impair individuals ability to process musical, linguistic, and emotional pitch. To date, it remains unclear why individuals with CA and ASD exhibit significant differences in music, speech, and emotion processing. Under our Delicate Form-Function Balance Hypothesis, we will conduct a series of behavioural and neurophysiological experiments to test the central hypothesis that normal musical, linguistic, and emotional functioning requires a delicate balance in the encoding and decoding of form and function in musical, speech, and emotional communication, with musical communication centred on form and linguistic and emotional communication focused on function. Most critically, we hypothesize that the differences in music, speech, and emotional processing in CA and ASD are rooted not only in pitch and cognitive abilities, but also in the balance between form and function for each domain. Addressing three specific aims regarding the impacts of cognitive processing styles, pitch processing skills, and language background (tone vs. non-tonal) on the behavioural and neurophysiological characteristics of music, language, and emotion processing in CA and ASD, this research will not only help reveal the underlying mechanisms of the two defining aspects of human cognition, music and language, but also form a laboratory for testing key hypotheses about the bio-behavioural manifestations of human neurodevelopmental disorders in music and language processing.
