The specifics of the manifestation of morphometric parameters of seeds in varietal populations of vegetable fennel (Foeniculum vulgare ssp. vulgare (Miller) Thell.)

open access: yesОвощи России, 2022
Seven accessions of vegetable fennel selection of the Federal Scientific Vegetable Center for Ecology were studied, in which significant differences were found in the degree of expression of the main morphological parameters (the length of the seed ...

Germs in a poset

open access: yesJournal of Algebraic Combinatorics, 2021
Motivated by the theory of correspondence functors, we introduce the notion of {\em germ} in a finite poset, and the notion of {\em germ extension} of a poset. We show that any finite poset admits a largest germ extension called its {\em germ closure}. We say that a subset $U$ of a finite lattice $T$ is {\em germ extensible} in $T$ if the germ closure ...

Silence in the Germ [PDF]

open access: yesCell, 2002
Gene expression in C. elegans germline cells is subject to strict controls. A set of MES proteins, including SET domain proteins and two homologs of Polycomb group proteins, establish an epigenetically transmitted silenced state that affects X chromosome gene expression.

Temperature sensitivity of DNA double-strand break repair underpins heat-induced meiotic failure in mouse spermatogenesis

open access: yesCommunications Biology, 2022
High temperatures lead to DNA double-strand break accumulation and asynapsis that trigger the meiotic checkpoint and apoptosis of spermatocytes in ex vivo cultures, providing a rationale for the heat sensitivity of sperm production in mammals.

Agronomic and physical traits of grain in transgenic and conventional corn for industrial use

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2022
The agronomic and physical traits of corn are fundamental for producers and industries that use this cereal as a raw material since they interfere in the industrialization processes, yield, and quality of the final products.

Productivity potential of maize hybrids developed at the P.P. Lukyanenko National Grain Center for deep grain processing

open access: yesТруды по прикладной ботанике, генетике и селекции, 2023
Background. The technology of deep grain processing is based on the use of operations that ensure separation of raw materials into various components and sequential processing of these components into products of high consumer value. The annual volume of
