Plant lineages diverge in DNA methylation without demethylases
An Arabidopsis preprint reports that methylation gains accumulated and differed among demethylase-mutant lineages over nine generations.

Blueberry flower buds lose a local ice barrier as spring arrives
A bioRxiv preprint reports that developing blueberry flowers remain ice-free in fall and winter even as surrounding bud tissues freeze, but lose that protection in spring as their water-conducting connections mature.

Viral RNA signature triggers two layers of plant antiviral defense
A bioRxiv preprint reports that double-stranded RNA restricts viral movement and RNA accumulation in a model plant, with the immune receptor COI1 implicated in the response.

Two mitochondrial genome configurations found in a model green alga
A bioRxiv preprint reports two mitochondrial DNA configurations in Chlamydomonas reinhardtii and proposes a model for how the genome might replicate.

Urban biowaste compost reshapes bacteria around tomato roots
A bioRxiv preprint reports a more diverse bacterial community and greater predicted functional potential in the rhizosphere of compost-treated tomato plants than in those given chemical fertilizer.

New Zealand helmet orchid seeds show uneven germination without fungi
A bioRxiv preprint reports that one of five Corybas species germinated on four tested media, while germination was limited in the others.

Tomato gene duplicates often retain ancestral expression patterns
A bioRxiv preprint compares duplicated tomato genes across 23 tissues, finding frequent retention of inferred ancestral expression and enrichment of fruit-quality functions among genes that gained fruit expression.

A sugar-binding protein helps a tomato pathogen multiply in leaves
A bioRxiv preprint reports that loss of the protein ThuE impairs growth of a tomato pathogen and greatly reduces its population in tomato leaves.

C4 leaf cells show distinct chloroplast-to-nucleus signalling
A bioRxiv preprint reports that two specialised leaf cell types in Setaria viridis show enrichment of different chloroplast-to-nucleus signalling pathways.

Fungal Volatiles Linked to Root Growth Under Osmotic Stress
A bioRxiv preprint reports that fungal volatile compounds promoted lateral root growth in Arabidopsis seedlings under both normal and osmotic-stress conditions, with signs of involvement from hormone, potassium and nitric oxide pathways.

Green algae show varied hydrogen responses when light returns after anoxia
A bioRxiv preprint reports that most tested algal strains produced hydrogen faster during their first illumination after dark anoxia than during later light cycles, but the size of the response varied widely.

Climate and arsenic conditions shift cadmium and zinc in rice grain
A pot experiment reported higher grain cadmium and lower zinc under combined arsenic contamination and simulated future climate conditions.

Rice may sense soil pH through changes in iron availability
A bioRxiv preprint proposes that rice responds to root-zone pH partly through iron availability and interactions between jasmonate and auxin signaling.

Soybean root profiles point to shifting defenses during nematode infection
A bioRxiv preprint reports a mismatch between defense-related gene activity and metabolites during soybean cyst nematode infection, alongside signals associated with legume symbiosis.
