  • GLV reveal species differences and responses to environment in alpine shrub Rosa sericea complex.

    Ruifang Jiao, Bohan Wu, Zhenlong Liang 他 · The Science of the total environment · 2023

    Plant Volatile components are an ecological adaptation mechanism of plants that can reflect species differences and environment information where it is located. The alpine shrub Rosa sericea complex consists of several allied species, which are morphologically similar and difficult to distinguish, they are typical distribution along the elevation in the Himalayas and the Transverse Ranges. We sele…

  • The peptide GOLVEN10 alters root development and noduletaxis in Medicago truncatula.

    Sonali Roy, Ivone Torres-Jerez, Shulan Zhang 他 · The Plant journal : for cell and molecular biology · 2024

    The conservation of GOLVEN (GLV)/ROOT MERISTEM GROWTH FACTOR (RGF) peptide encoding genes across plant genomes capable of forming roots or root-like structures underscores their potential significance in the terrestrial adaptation of plants. This study investigates the function and role of GOLVEN peptide-coding genes in Medicago truncatula. Five out of fifteen GLV/RGF genes were notably upregulate…

  • Herbivorous Caterpillars and the Green Leaf Volatile (GLV) Quandary.

    Anne C Jones, Tristan M Cofer, Jurgen Engelberth 他 · Journal of chemical ecology · 2022

    Several herbivorous caterpillars contain effectors in their oral secretions that alter the emission of green leaf volatiles (GLVs) produced by the plants upon which the caterpillars are feeding. These effectors include an isomerase, a fatty acid dehydratase (FHD), and a heat-stable hexenal trapping (HALT) molecule. GLVs serve as signaling compounds in plant-insect interactions and inter-and intra-…

  • Integrated transcriptome and metabolome analyses shed light on the defense mechanisms in tomato plants after (E)-2-hexenal fumigation.

    Jihong Zhang, Quanwu Liang, Yuqiong Li 他 · Genomics · 2023

    Tomato is a widely cultivated fruit and vegetable and is valued for its flavor, colour, and nutritional value. C6-aldehydes, such as (E)-2-hexenal, not only have antibacterial and antifungal properties but also function as signaling molecules that control the defense mechanisms of plants, including tomatoes. In this study, we used liquid chromatography-mass spectrometry (LC-MS) and RNA sequencing …

  • Dynamic GOLVEN-ROOT GROWTH FACTOR 1 INSENSITIVE signaling in the root cap mediates root gravitropism.

    Ke Xu, Joris Jourquin, Xiangyu Xu 他 · Plant physiology · 2023

    Throughout the exploration of the soil, roots interact with their environment and adapt to different conditions. Directional root growth is guided by asymmetric molecular patterns but how these become established or are dynamically regulated is poorly understood. Asymmetric gradients of the phytohormone auxin are established during root gravitropism, mainly through directional transport mediated b…

  • The anti-oxidative, anti-cell proliferative and anti-microbial efficacies of cold-adapted Crepis flexuosa: HPTLC and GC/MS analyses.

    Mohammad K Parvez, Mohammed S Al-Dosari, Sarfaraz Ahmed 他 · Saudi journal of biological sciences · 2022

    The genus Crepis constitutes cold-adapted plant spp., of these some are traditionally used in folk medicine against inflammation or fungal infections without scientific validations. Here, we report the biological activities of Crepis flexuosa total ethanol-extract (CF-EtOH) and its hexane (CF-Hex), ethyl acetate (CF-EtOA), butanol (CF-ButOH), and aqueous (CF-Aqua) fractions. Our in vitro DPPH and …

  • Intraspecific variation of scent and its impact on pollinators' preferences.

    Mayumi Vega-Polanco, Lislie Solís-Montero, Julio C Rojas 他 · AoB PLANTS · 2023

    Floral scents shape plant-pollinator interactions. Although populations of the same species can vary in their floral scent, little is known about how this variation affects pollinator visitation. In this study, we compare the scents emitted by buzz-pollinated Solanum rostratum (Solanaceae) in two areas of its distribution (Mexico and USA) and investigate how these differences in scent affect polli…

  • Mosquito Larvicidal Activity and Cytotoxicity of the Extracts of Aromatic Plants from Malaysia.

    Huimei Lim, Sook Yee Lee, Lai Yee Ho 他 · Insects · 2023

    Despite ongoing control efforts, the mosquito population and diseases vectored by them continue to thrive worldwide, causing major health concerns. There has been growing interest in the use of botanicals as alternatives to insecticides due to their widespread insecticidal properties, biodegradability, and adaptability to ecological conditions. In this study, we investigated the larvicidal activit…

  • Cuticular Wax Variability of Abies alba, A.×borisii-regis and A. cephalonica from the Balkans: Chemophenetic and Ecological Aspects.

    Zorica S Mitić, Jelena S Nikolić, Ivana S Dimitrijević 他 · Chemistry & biodiversity · 2023

    This is the first study on cuticular wax variability of Abies alba, A.×borisii-regis and A. cephalonica, using 18 native populations from the assumed hybrid zone in the Balkan Peninsula. Presence of 13 n-alkanes with chain-lengths ranging from C21 to C33 , one primary alcohol, two diterpenes, one triterpene and one sterol was determined in hexane extracts of 269 needle samples. The multivariate st…

  • Pigment structure in the violaxanthin-chlorophyll-a-binding protein VCP.

    Manuel J Llansola-Portoles, Radek Litvin, Cristian Ilioaia 他 · Photosynthesis research · 2017

    Resonance Raman spectroscopy was used to evaluate pigment-binding site properties in the violaxanthin-chlorophyll-a-binding protein (VCP) from Nannochloropsis oceanica. The pigments bound to this antenna protein are chlorophyll-a, violaxanthin, and vaucheriaxanthin. The molecular structures of bound Chl-a molecules are discussed with respect to those of the plant antenna proteins LHCII and CP29, t…
