Calyx-end cracking in 'Pink Lady' apple is treated by a solution of gibberellic acids 4 and 7 (GA4+7 ) and the cytokinin 6-benzyladenine (BA). Although the GA4+7 and BA mixture is applied early in apple fruit development, it mitigates cracking that becomes evident in the mature fruit, implying a long-term treatment effect. The reduced incidence of peel cracking is associated with increased epidermal cell density, which is maintained until fruit maturation. Presently, the expression of genes that have been previously reported to be associated with epidermal cell patterning and cuticle formation, or cracking resistance, was monitored in the peel during fruit development and following GA4+7 and BA treatment...

Triterpenoic acids, ursolic acid (1), oleanolic acid (2), glycyrrhetinic acid (3) and betulinic acid (4) were converted into their corresponding methyl 5-8 and benzyl esters 9-12 or benzyl amides 21-24. These derivatives served as starting materials for the synthesis of pink colored rhodamine B derivatives 25-36 which were screened for cytotoxicity in colorimetric SRB assays. All of the compounds were cytotoxic for a variety of human tumor cell lines. The activity of the benzyl ester derivatives 29-32 was lower than the cytotoxicity of the methyl esters 25-28...

Victoria (Nymphaeaceae), an annual or perennial aquatic plant genus, contains only two species: V. amazonica (Poepp.) J. C. Sowerby and V. cruziana A. D. Orb. Both species exhibit large floating leaves and variable flower color. Both Victoria are night bloomers, which have white petals on the first blooming night, which then turn pink or ruby red on the second blooming day. The mechanism of the color change of Victoria petals during anthesis is still unclear. In this study, flavonoids in Victoria petals of both species were evaluated and quantified by high-performance liquid chromatography with photodiode array detection (HPLC-DAD) and by ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) for the first time...

Color and other quality parameters of "Redglobe" grape ( Vitis vinifera L.) berries were evaluated after treatment with brassinosteroid (BR) analogs. Three BRs analogs (24-epibrassinolide, Triol, or Lactone) were applied at three concentrations (0.0, 0.4, or 0.8 mg⋅L-1 ), at the onset of veraison. A commercial formulation (B-2000® ) was also applied, at a recommended rate of 0.06 mg⋅L-1 . The tested BR analogs were effective improving berry color (evaluated as color index for red grapes, CIRG), increasing the levels of soluble solids and anthocyanins, and changing the types of anthocyanins present without altering other quality and yield parameters...

Chrysanthemum ( Chrysanthemum morifolium Ramat.) is one of the most important floricultural crops in the world. Although the origin of modern chrysanthemum cultivars is uncertain, several species belonging to the family Asteraceae are considered to have been integrated during the long history of breeding. The flower color of ancestral species is limited to yellow, pink, and white, and is derived from carotenoids, anthocyanins, and the absence of both pigments, respectively. A wide range of flower colors, including purplish-red, orange, red, and dark red, has been developed by increasing the range of pigment content or the combination of both pigments...

5-Methyl-2-phenyl-2H-1,2,3-triazole-4-carboxylic acid (MPTC), a newly synthesized compound, was explored to study the structural properties and theoretical spectra by using GaussView5.0 program package and the time dependent density functional theory (TD DFT). The calculated quantum chemical values suggested that it is easy for MPTC to lose electron with weak electron accepting ability. And the results of experimental measurements on fluorescence and absorption spectra were consistent with that of the calculated spectra in great degree...

As the species Haploclastus devamatha Prasanth & Jose, 2014 is indistinguishable from Thrigmopoeus psychedelicus Sanap & Mirza, 2014, the latter is herein considered junior synonym of the former. Occurrence of polychromatism in H. devamatha is noted, and two distinct colour morphs of the species are recognised, a pink form and a blue form. The natural history and conservation of the species are discussed and its known distribution is updated.

Hierarchical assembly provides a route to complex architectures when using building blocks with strong and structurally well-defined recognition elements. These rules are expressed using cationic templates with reliable metal-ligand bonding but use of anions is rare on account of weak anion-host contacts. We investigate an approach that relies on host-host interactions to fortify assemblies formed between bisulfate anion dimers, [HSO4***HSO4]2-, and shape-persistent macrocycles called tricarbazole triazolophanes...

BACKGROUND: Many cyanobacteria are capable of fixing atmospheric nitrogen, playing a crucial role in biogeochemical cycling. Little is known about freshwater unicellular cyanobacteria Synechococcus spp. at the genomic level, despite being recognised of considerable ecological importance in aquatic ecosystems. So far, it has not been shown whether these unicellular picocyanobacteria have the potential for nitrogen fixation. Here, we present the draft-genome of the new pink-pigmented Synechococcus-like strain Vulcanococcus limneticus...
