Internal regulation between constitutively expressed T cell coinhibitory receptors BTLA and CD5 and tolerance in recent thymic emigrants

This study identifies a regulatory pathway between BTLA and CD5 in T cells that calibrates their expression to establish self-tolerance in recent thymic emigrants.

BZR1 promotes pluripotency acquisition and callus development through direct regulation of ARF7 and ARF19

This study shows BZR1 promotes pluripotency and callus formation by directly regulating ARF7 and ARF19 in plants.

Chewing Through Challenges: Exploring the Evolutionary Pathways to Wood-Feeding in Insects

This paper investigates the evolutionary origins of saproxylophagy in insects, proposing the Detritivore-First Hypothesis and emphasizing the role of gut microbiomes in wood digestion.

Sensing of viral RNA in plants via a DICER-LIKE Ribonuclease

The paper shows that plant DCL2 triggers RNAi-independent defense gene expression via NLR receptors and redefines plant antiviral immunity by linking DCL2 to double-stranded RNA sensing and autoimmunity.

Tyramine and its AmTYR1 receptor modulate attention in honey bees (Apis mellifera)

This study identifies a genetic pathway involving the AmTYR1 receptor that modulates latent inhibition in honey bees, suggesting a role in inhibitory processing and Hebbian plasticity in the CNS.

PAT mRNA decapping factors function specifically and redundantly during development in Arabidopsis

The paper investigates the roles of PAT mRNA decapping factors in Arabidopsis development, showing specific and redundant functions in growth and leaf morphology.

Phylogenomics reveals the evolutionary origin of lichenization in chlorophyte algae

The paper investigates the evolutionary origin of lichenization in chlorophyte algae by analyzing genomes and transcriptomes of lichen algal symbionts and non-symbiotic algae, identifying convergent evolution and horizontal gene transfer as key factors.

The evolution of the phenylpropanoid pathway entailed pronounced radiations and divergences of enzyme families

This study shows that enzyme families in the phenylpropanoid pathway underwent radiations and divergences in land plants and their algal relatives, suggesting evolutionary versatility in specialized metabolism.

Are fleas highly modified Mecoptera? Phylogenomic resolution of Antliophora (Insecta: Holometabola)

This study uses transcriptomic data to resolve the phylogenetic relationships within Antliophora, finding fleas are sister to either a monophyletic Mecoptera or arose within mecopteran families, potentially making Mecoptera paraphyletic.

A collection of programs for one-dimensional Ising analysis of linear repeat proteins with point substitutions

The paper presents programs for analyzing the thermodynamics of linear repeat proteins using a 1D Ising model to study folding and mutation effects.

mRNA decapping machinery targets LBD3/ASL9 transcripts to authorize developmental reprogramming in Arabidopsis

The paper shows that mRNA decapping regulates LBD3/ASL9 transcript levels to balance cytokinin/auxin responses during developmental reprogramming in Arabidopsis.

Improving the chromosome-level genome assembly of the Siamese fighting fish (Betta splendens) in a university Master's course.

The paper improves the chromosome-level genome assembly of the Siamese fighting fish using long-read nanopore sequencing and HiC scaffolding, demonstrating educational application in a Master's course.

Autophagy mediates temporary reprogramming and dedifferentiation in plant somatic cells

This study shows autophagy is essential for temporary reprogramming and dedifferentiation in plant somatic cells, enabling adaptation to environmental changes and cellular reprogramming.
