Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, EarlyView.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...

CENH3: AN EMERGING PLAYER IN HAPLOID INDUCTION TECHNOLOGY

Frontiers in Plant Science, 2016
True-breeding lines are required for the development and production of crop varieties. In a classical breeding approach these lines are obtained through inbreeding, and often 7-9 generations of inbreeding is performed to achieve the desired level of ...

CRISPR/Cas9 Genome Engineering in Non‐Conventional Oleaginous Yeasts: Applications, Challenges, and Prospects

Yeast, EarlyView.
ABSTRACT Given the biotechnological potential of yeast‐derived oils for oleochemical production, genes encoding lipid metabolism enzymes are key targets for metabolic engineering. Genetic engineering tools such as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9, Transcription Activator‐Like Effector Nucleases (TALENs), Zinc ...

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Detection of sex chromosomes in Tephritid pests using R‐CQ and KAMY, two computational methods to support generic pest management applications

Insect Science, EarlyView.
Here, we present R‐CQ and KAMY, two computational methods developed for the detection of sex chromosome‐linked sequences. We evaluate their performance on newly generated chromosome‐level assemblies of four important Tephritid pest species: Ceratitis capitata, Bactrocera dorsalis, Bactrocera zonata, and Anastrepha ludens.

On the issue of producing doubled haploids of table beet (Beta vulgaris L. var. conditiva Alef.) (a review)

Труды по прикладной ботанике, генетике и селекции
Currently, hybrid table beet seeds make up a significant part of the seeds sold in the world due to their high synchrony, root uniformity, and the effect of heterosis. Heterosis breeding of table beet in Russia is developed insufficiently.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Vibratome Sectioning and Clearing for Easing Studies of Cassava Embryo Formation

Frontiers in Plant Science, 2020
This work describes the application of clearing on vibratome sections to study the embryo formation in cassava. This procedure provides high-resolution images and reduces significantly the number of sections that need to be analyzed per ovule.

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...
