  • Detection of wheat allergens using 2D Western blot and mass spectrometry. [Review]
    J Pharm Biomed Anal 2019; 178:112907Courtois J, Bertholet C, … Quinting B
  • CONCLUSIONS: The present study allowed the identification of different protein areas specific to these studied groups. The protein spots of interest were identified by UHPLC-MS/MS. It has been possible to establish a link between a specific symptomatology and the newly identified responsible allergens.
  • 'A most complex marriage arrangement': recent advances on heterostyly and unresolved questions. [Review]
    New Phytol 2019; 224(3):1051-1067Barrett SCH
  • Heterostylous genetic polymorphisms provide paradigmatic systems for investigating adaptation and natural selection. Populations are usually comprised of two (distyly) or three (tristyly) mating types, maintained by negative frequency-dependent selection resulting from disassortative mating. Theory predicts this mating system should result in equal style-morph ratios (isoplethy) at equilibrium. H…
  • Energy metabolism involved in fertility of the wheat TCMS line YS3038. [Journal Article]
    Planta 2019Han Y, Gao Y, … Ma L
  • CONCLUSIONS: In the wheat TCMS line YS3038, the anther development is inhibited from late uninucleate stage to the binucleate stage. The disruption of energy metabolism pathways by aberrant transcriptional regulation causes the male sterility under low temperatures. The utilization of thermosensitive male sterile (TMS) lines provides a basis for two-line breeding. Previous work, including morphological and cytological observations, has shown that the development process of the TMS line YS3038 is inhibited from the late uninucleate stage to the binucleate stage. Transcriptomics studies could now help to elucidate the overall expression of related genes in a specific reproductive process, revealing the metabolic network and its regulatory mechanism of the reproductive process from the transcription level. Considering the fertility characteristics of YS3038, three important stages for transcriptome analysis were determined to be the early uninucleate, late uninucleate and binucleate stages. The number of differentially expressed genes (DEGs) was found to be highest in the binucleate stage, and most were related to energy metabolism. Quantitative PCR analysis of selected genes related to energy metabolism revealed that their expression patterns were consistent with the sequencing results. Analysis of the fertility mechanism of YS3038 showed that although the tapetum of anthers was degraded in advance of the tetrad stage, the development of microspores did not result in obvious abnormalities until the binucleate stage, because the genes involved in energy metabolism pathways, including starch and sucrose metabolism (SSM), glycolysis, the tricarboxylic acid (TCA) cycle, oxidative phosphorylation, and respiration electron transport chain are differentially expressed under sterile and fertile conditions. Therefore, the pollen in YS3038 was sterile.
  • Cryo-EM Structure of Actin Filaments from Zea mays Pollen. [Journal Article]
    Plant Cell 2019Ren Z, Zhang Y, … Ren H
  • Actins are among the most abundant and conserved proteins in plant, mammalian and other eukaryotic cells, where they form filamentous structures to perform vital roles in key cellular processes. Although large amounts of data on the biochemical activities, dynamic behaviors and important cellular functions of plant actin filaments have been accumulated, their structural basis is still elusive. He…
  • Expansin gene loss is a common occurrence during adaptation to an aquatic environment. [Journal Article]
    Plant J 2019Hepler NK, Bowman A, … Cosgrove DJ
  • Expansins comprise a superfamily of plant cell wall loosening proteins which can be divided into four individual families (EXPA, EXPB, EXLA, EXLB). Aside from inferred roles in a variety of plant growth and developmental traits, little is known regarding function of specific expansin clades, for which there are at least 16 in flowering plants (angiosperms). However, there is evidence to suggest s…
  • Structural diversity and functional variability of gut microbial communities associated with honey bee. [Review]
    Microb Pathog 2019; :103793Khan KA, Al-Ghamdi AA, … Hafeez M
  • Microbial consortia accompanied to all eukaryotes can be inherited from ancestors, environment, and/or from various food source. Gut microbiota study is an emerging discipline of biological sciences that expands our understanding of the ecological and functional dynamics of gut environments. Microorganisms associated with honey bees play an important role in food digestion, colony performance, im…
