Root attributes dominate the community assembly of soil fungal functional guilds across arid inland river basin

open access: yesFrontiers in Microbiology, 2022
Plant attributes are increasingly acknowledged as key drivers shaping soil fungal communities, but considerable uncertainty exists over fungal community assembly mechanisms and their plant drivers based only on inferences from plant aboveground ...

Breeding polyploid Populus: progress and perspective

open access: yesForestry Research, 2022
Populus is a genus of 25−30 species of deciduous flowering plants in the family Salicaceae, which are primarily planted in short-rotation planations for producing timber, pulpwood, wooden products as well as bioenergy feedstock; they are also widely ...

Transcription factor PagLBD21 functions as a repressor of secondary xylem development in Populus

open access: yesForestry Research, 2022
During secondary growth in trees, xylem cells differentiated from cambium cells begin to synthesize secondary cell walls that are primarily composed of cellulose, hemicellulose and lignin, and are deposited between primary cell walls and plasma membranes,

Identification of AP2/ERF gene family of Salicaceae and their response to salt stress, abscisic acid, and gibberellic acid in Populus euphratica seeds

open access: yesBiologia Plantarum, 2023
Populus euphratica belongs to Salicaceae family and grows in extreme desert environments. At present, the identification of the AP2/ERF gene family of transcription factors in Salicaceae is rare, and the role of the AP2/ERF gene family in P.

Anthocyanins of the anthers as chemotaxonomic markers in the genus Populus L.. Differentiation between Populus nigra, Populus alba and Populus tremula [PDF]

open access: yesPhytochemistry, 2016
Three main species of Popululs L. (Salicaceae) have been reported to occur in the Iberian Peninsula: Populus nigra L., Populus alba L. and Populus tremula L. The degree of pilosity of the bracts of the male catkins is a key character for their differentiation. The anthers of these poplar species possess anthocyanins that provide them a red colouration.

Brassinosteroid Signaling Converges With Auxin-Mediated C3H17 to Regulate Xylem Formation in Populus

open access: yesFrontiers in Plant Science, 2020
Brassinosteroid (BR) signaling has long been reported to have an effect on xylem development, but the detailed mechanism remains unclear, especially in tree species. In this study, we find PdC3H17, which was demonstrated to mediate xylem formation driven

Chromosome-scale assemblies of the male and female Populus euphratica genomes reveal the molecular basis of sex determination and sexual dimorphism

open access: yesCommunications Biology, 2022
Reference-quality genomes of both sexes of the dioecious tree species, Populus euphratica, provide further insight into the evolution of Populus sex chromosomes and highlight male-specific fusion genes that may contribute to sexual dimorphism.
