As such, it provides a source of support to help students and early career scientists from under-represented groups learn about maize genetics and connect with scientists already in the community. Awardees are not required to have previous maize genetics research experience, but will hopefully develop an appreciation of the current excitement in the field, and become an integral part of the community in the future. The program also provides an opportunity for awardees to explore potential collaborations and develop career contacts. Each MaGNET Award helps defray the cost of attending the Maize Genetics Conference, including registration, food, lodging and airfare. In addition, awardees that have never attended the MGC are paired with an experienced ‘Maize Mentor’, who will help the awardee navigate the conference. Awardees are identifiable by a special notation on their name tags, and many of them are attending the MGC for the first time – please congratulate these scientists and welcome them to our famously hospitable conference! All applicants must show strong potential for a career in the biological sciences, be either citizens or permanent residents of the USA, and belong to a group traditionally underrepresented in science. To help provide a more integrative and effective experience at the Conference for student awardees, faculty mentors who accompany one or more eligible student applicants are also eligible to apply for a MaGNET award. 2017 MaGNET Awardees Undergraduate Sarfo Kantanka, Florida A&M University Daniel Hayden, University of Oklahoma Brianna Griffin, Florida State University Poster #144 Jason Peters, Southern University Graduate Student Jonas Rodriguez, University of Wisconsin-Madison Janette Mendoza, University of New Mexico Poster #221 Roberto Alers Velazquez, University of Toledo Aimee Uyehara, University of Hawaii at Manoa Poster #128 Mentor Accompanying Student Gokhan Hacisalihoglu, Florida A&M University Poster #94 Katy Guthrie, University of Missouri-Columbia Poster #72 Laura Morales, Cornell University Poster #298 Subbaiah Chalivendra, Louisiana State University Poster #293 John Gray, University of Toledo Poster #67 Maria Angelica Sanclemente, University of Florida Poster #107 Brett Burdo, University of Wisconsin-Madison Poster #292 Angel Del Valle Echevarria, University of Hawaii at Manoa Poster #189 The MaGNET program of the Maize Genetics Conference is supported by grant IOS-1659999 from the National Science Foundation. vi Schedule of Events Talks will be held in the Regency Ballroom.

A total of 2110 proteins were identified in “Huangjinya”, and 173 proteins showed differential accumulations between the chlorotic and normal green leaves. Of these, 19 proteins were correlated with RNA expression levels, based on integrated analyses of the transcriptome and proteome. Moreover, the results of our analysis of differentially expressed proteins suggested that primary carbon metabolism (i.e., carbohydrate synthesis and transport) was inhibited in chlorotic tea leaves. The differentially expressed genes and proteins combined with photosynthetic phenotypic data indicated that 4-coumarate-CoA ligase (4CL) showed a major effect on repressing flavonoid metabolism, and abnormal developmental chloroplast inhibited the accumulation of chlorophyll and flavonoids because few carbon skeletons were provided as a result of a weakened primary carbon metabolism.

Merr.) chlorophyll deficient line MinnGold is a spontaneous mutant characterized by yellow foliage. Map-based cloning and transgenic complementation revealed that the mutant phenotype is caused by a non-synonymous nucleotide substitution in the third exon of a Mg-chelatase subunit gene (ChlI1a) on chromosome 13. This gene was selected as a candidate for a different yellow foliage mutant, T219H (Y11y11), that had been previously mapped to chromosome 13.

  • First Comprehensive Proteome Analysis of Lysine Crotonylation In
    www.nature.com/scientificreports OPEN First comprehensive proteome analysis of lysine crotonylation in seedling leaves of Nicotiana Received: 12 January 2017 Accepted: 25 April 2017 tabacum Published: xx xx xxxx Hangjun Sun1, Xiaowei Liu1, Fangfang Li1, Wei Li2, Jing Zhang2, Zhixin Xiao3, Lili Shen1, Ying Li1, Fenglong Wang1 & Jinguang Yang1 Histone crotonylation is a new lysine acylation type of post-translational modification (PTM) enriched at active gene promoters and potential enhancers in yeast and mammalian cells. However, lysine crotonylation in nonhistone proteins and plant cells has not yet been studied. In the present study, we performed a global crotonylation proteome analysis of Nicotiana tabacum (tobacco) using high- resolution LC-MS/MS coupled with highly sensitive immune-affinity purification. A total of 2044 lysine modification sites distributed on 637 proteins were identified, representing the most abundant lysine acylation proteome reported in the plant kingdom. Similar to lysine acetylation and succinylation in plants, lysine crotonylation was related to multiple metabolism pathways, such as carbon metabolism, the citrate cycle, glycolysis, and the biosynthesis of amino acids. Importantly, 72 proteins participated in multiple processes of photosynthesis, and most of the enzymes involved in chlorophyll synthesis were modified through crotonylation. Numerous crotonylated proteins were implicated in the biosynthesis, folding, and degradation of proteins through the ubiquitin-proteasome system. Several crotonylated proteins related to chromatin organization are also discussed here. These data represent the first report of a global crotonylation proteome and provide a promising starting point for further functional research of crotonylation in nonhistone proteins. Post-translational modification (PTM) is a covalent modification process resulting from the proteolytic cleavage or addition of a functional group to one amino acid.

  • Mutation Mechanism of Leaf Color in Plants: a Review
    Review Mutation Mechanism of Leaf Color in Plants: A Review Ming-Hui Zhao, Xiang Li, Xin-Xin Zhang, Heng Zhang and Xi-Yang Zhao * State Key Laboratory of Tree Genetics and Breeding, School of Forestry, Northeast Forestry University, Harbin 150040, China; [email protected] (M.-H.Z.); [email protected] (X.L.); [email protected] (X.-X.Z.); [email protected] (H.Z.) * Correspondence: [email protected]; Tel.: +86-0451-8219-2225 Received: 3 July 2020; Accepted: 3 August 2020; Published: 6 August 2020 Abstract: Color mutation is a common, easily identifiable phenomenon in higher plants. Color mutations usually affect the photosynthetic efficiency of plants, resulting in poor growth and economic losses. Therefore, leaf color mutants have been unwittingly eliminated in recent years. Recently, however, with the development of society, the application of leaf color mutants has become increasingly widespread. Leaf color mutants are ideal materials for studying pigment metabolism, chloroplast development and differentiation, photosynthesis and other pathways that could also provide important information for improving varietal selection. In this review, we summarize the research on leaf color mutants, such as the functions and mechanisms of leaf color mutant-related genes, which affect chlorophyll synthesis, chlorophyll degradation, chloroplast development and anthocyanin metabolism. We also summarize two common methods for mapping and cloning related leaf color mutation genes using Map-based cloning and RNA-seq, and we discuss the existing problems and propose future research directions for leaf color mutants, which provide a reference for the study and application of leaf color mutants in the future. Keywords: color mutation; pigment metabolism; chlorophyll; anthocyanin; mutation mechanism; RNA-seq 1.
