Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Floral stage optimization and immune evasion enhance Agrobacterium‐mediated genome editing in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2125-2139, February 2026.
Summary Agrobacterium‐mediated transformation by floral inoculation (AMT‐FI) enables genetic engineering without tissue culture. It is widely used in the model plant Arabidopsis thaliana, yet its efficiency and broader applicability remain limited. Here, we used a dual‐reporter system (RUBY and hygromycin resistance) to identify key floral stages and ...

The Dark Side of Stress Response: Night Temperature Regimes Drive Distinct Abiotic Pathways in Legumes

open access: yesPlant, Cell &Environment, Volume 49, Issue 2, Page 925-939, February 2026.
ABSTRACT Global warming increases night temperatures more strongly than day temperatures. Recent evidence indicates that the effect of night temperature on plant physiology is independent of daytime conditions, suggesting distinct stress tolerance mechanisms.

Seed evolution: parental conflicts in a multi-generational household [PDF]

open access: yes, 2017
Seeds are multi-generational structures containing a small embryonic plant enclosed in layers of diverse parental origins. The evolution of seeds was a pinnacle in an evolutionary trend towards a progressive retention of embryos and gametes within ...

DNA methylation and epigenetic inheritance during plant gametogenesis [PDF]

open access: yes, 2018
In plants, newly acquired epigenetic states of transcriptional gene activity are readily transmitted to the progeny. This is in contrast to mammals, where only rare cases of transgenerational inheritance of new epigenetic traits have been reported (FASEB

Scientific results of the Bryotrop expedition to Zaire and Rwanda : 7., life strategies of epiphytic bryophytes from tropical lowland and montane forests, ericaceous woodlands and the Dendrosenecio subpáramo of the eastern Congo basin and the adjacent mountains (Parc National de Kahuzi-Biega/Zaire, Forêt de Nyungwe/Rwanda) [PDF]

open access: yes, 1995
Life strategies of epiphytic bryophytes are studied along an altitudinal gradient from the eastern Congo basin (tropical lowland zone) to the mountains of the East-African graben (tropical subalpine/alpine Zone; BRYOTROP III-transect).

Timing of megasporogenesis in Tripsacum species (Poaceae) as related to the control of apoximis and sexuality [PDF]

open access: yes, 1994
Chez différentes espèces pseudogames aposporiques (#Panicum maximum, Ranunculus auricomus, Paspalumnotatum$), des différences pour la durée de la mégasporogenèse ont été observées entre les formes sexuées et aposporiques ; les gamétophytes femelles ...
