Genetic Susceptibility to Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

Longevity in plants impacts phylogenetic and population dynamics

open access: yesNew Phytologist, EarlyView.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

open access: yesNew Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Small RNAs regulation and genomic harmony: insights into allopolyploid evolution in marsh orchids (Dactylorhiza)

open access: yesNew Phytologist, EarlyView.
Summary Hybridization and polyploidy are major drivers of plant diversification, often accompanied by shifts in gene expression and genome composition. Small RNAs (smRNAs) are thought to influence such genomic changes, particularly through their interactions with transposable elements (TEs).

Equine Spermatogenesis: Meiotic Chromosome Behavior and Recombination [PDF]

open access: yes
Studying the spermatogenesis of horse is beneficial for the horse industry by identifying the causes of chromosomal abnormalities, which cause embryonic loss, congenital abnormalities and infertility. Little is known about the spermatogenesis in horse.

Perturbation of Anion/Cation Transport Leads to Apical Panicle Abortion in Rice by Disrupting Ca2+ Homeostasis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Calcium ion (Ca2+) is an essential plant nutrient required for cell structure establishment, as well as a counter‐cation of an anion and an intracellular messenger. Calcium is absorbed from soil by roots and delivered to shoots through the xylem. The process must be finely balanced to avoid excessive accumulation.

Induction of Synthetic Apomixis in Two Sorghum Hybrids Enables Seed Yield and Genotype Preservation Over Multiple Generations

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Induction of apomixis, or clonal reproduction through seed, could economise commercial hybrid seed production and enable smallholder farmers to save and sow hybrid seed. Here, we demonstrate the synthetic induction of apomixis in two sorghum hybrids and show that the clonal hybrid seed can be maintained across multiple seed generations.
