Silver fir is one of the longest living and tallest trees in Europe, it has major commercial importance and may be found in various communities predominantly connected with lower mountainous locations...
A microbiota–root–shoot circuit favours Arabidopsis growth over defence under suboptimal light
Arabidopsis suboptimal light MYC2 root–shoot signalling
2023/12/4
Bidirectional root–shoot signalling is probably key in orchestrating stress responses and ensuring plant survival. Here, we show that Arabidopsis thaliana responses to microbial root commensals and li...
Single-cell transcriptomics sheds light on the identity and metabolism of developing leaf cells
Single-cell transcriptomics photosynthetic Arabidopsis thaliana high-throughput transcriptome metabolic stress-related
2023/11/30
As the main photosynthetic instruments of vascular plants, leaves are crucial and complex plant organs. A strict organization of leaf mesophyll and epidermal cell layers orchestrates photosynthesis an...
γ-Aminobutyric acid plays a key role in plant acclimation to a combination of high light and heat stress
c-Aminobutyric acid high light heat stress Arabidopsis thaliana abiotic stresses metabolic response GABA
2023/11/30
Plants are frequently subjected to different combinations of abiotic stresses, such as high light (HL) intensity, and elevated temperatures. These environmental conditions pose a threat to agriculture...
The genome of homosporous maidenhair fern sheds light on the euphyllophyte evolution and defences
Adiantum capillus-veneris evolution of seed plants origin of euphyllophytes defences
2023/11/16
Euphyllophytes encompass almost all extant plants, including two sister clades, ferns and seed plants. Decoding genomes of ferns is the key to deep insight into the origin of euphyllophytes and the ev...
Jasmonic acid is required for plant acclimation to a combination of high light and heat stress
Jasmonic acid heat stress high light stress plant acclimation
2024/2/27
In the field, plants experience high light intensities that are often accompanied by elevated temperatures. Such conditions are a serious threat to agriculture production, since photosynthesis is high...
