Chromosome‐level genome and methylome of vine tea suggest roles for tandem duplication and CHH hypomethylation in high dihydromyricetin accumulation

open access: yesiMetaOmics, EarlyView.
A chromosome‐level genome assembly and single‐base resolution methylome of vine tea (Nekemias grossedentata) reveal that lineage‐specific tandem duplications of dihydromyricetin (DHM) biosynthetic genes (NgCHS and NgF3′5′ H) have expanded their copy numbers, providing the genetic basis for high DHM flux.

Chromatin structure and transposable elements in organismal aging

open access: yesFrontiers in Genetics, 2013
Epigenetic regulatory mechanisms are increasingly appreciated as central to a diverse array of biological processes, including aging. An association between heterochromatic silencing and longevity has long been recognized in yeast, and in more recent ...

Two near‐complete assemblies reveal R‐subgenome structural and centromeric divergence associated with reproductive isolation in hexaploid triticale

open access: yesiMeta, EarlyView.
We present two near‐complete triticale genome assemblies and perform pan‐centromere analyses across >200 haplotypes from parental species, synthetic allopolyploids, cultivars, and 337 resequenced accessions, revealing a shared chromatin framework underlying functional centromeres in all three subgenomes, where wheat‐ and rye‐derived CENH3 co‐occupy ...

Characterization of two non-LTR retrotransposons from Sogatella furcifera and Nilaparvata lugens [PDF]

open access: yesArthropods, 2019
The fiWe have cloned two retrotransposons, one named SF-RT from Sogatella furcifera and another named NL-Rt from Nilaparvata lugens genome. Both SF-RT and NL-RT are members of the Daphne clade, and encode two open reading frames (ORFs) required for ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Effect of environmental and genetic factors on the stability of pea (Pisum sativum L.) isozyme and DNA markers

open access: yesCzech Journal of Genetics and Plant Breeding, 2009
Environmental (geographic location, year-to-year effect) and genetic (intravarietal variation) effects on the stability of the isozyme patterns of esterase (EST), acid phosphatase (ACP), alcohol dehydrogenase (ADH), leucine aminopeptidase (LAP ...

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

open access: yesPest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Mobile genetic elements – mechanism and consequences of transposition

open access: yesJournal of Education, Health and Sport, 2017
Retrotransposons represent a significant part of the genome in eukaryote organisms. With DNA transposons, they belong to mobile genetic elements. There are two classes of transposons, DNA transposons and retrotransposons.

Maternal LSD1/KDM1A is an essential regulator of chromatin and transcription landscapes during zygotic genome activation

open access: yeseLife, 2016
Upon fertilization, the highly specialised sperm and oocyte genomes are remodelled to confer totipotency. The mechanisms of the dramatic reprogramming events that occur have remained unknown, and presumed roles of histone modifying enzymes are just ...

How Retroviruses and Retrotransposons in Our Genome May Contribute to Autoimmunity in Rheumatological Conditions

open access: yesFrontiers in Immunology, 2020
More than 200 human disorders include various manifestations of autoimmunity. The molecular events that lead to these diseases are still incompletely understood and their causes remain largely unknown.
