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...

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...
The asparagus genome sheds light on the origin and evolution of a young Y chromosome
雄性双倍体 芦笋 石刁柏 基因组测序
