is a tree species of Magnoliaceae as least concern. In the present paper, the complete chloroplast genome (cpDNA) and basic annotated information of were reported and its phylogenetic relationship with other species in Magnoliaceae was analyzed. The size of its complete cpDNA is 159,693 bp, with a typical quadripartite structure comprising a pair of inverted repeat (IR) regions of 26,546 bp, a large single-copy (LSC) region of 87,848 bp and a small single-copy (SSC) region of 18,753 bp. The genome contains 131 unique genes, including 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic analysis showed that is affinal to and they form a monophyletic group with other seven species. This clade is sister to the and clade with high support. All genera mentioned in this analysis are monophyletic under the system of Magnoliaceae by Sima and Lu.

Stomatal closure is a pervasive response among trees exposed to flooded soil. We tested whether this response is caused by reduced hydraulic conductance in the soil-to-leaf hydraulic continuum (k), and particularly by reduced root hydraulic conductance (k), which has been widely hypothesized. We tracked stomatal conductance at the leaf level (g) and canopy scale (G) along with physiological conditions in two temperate tree species, Magnolia grandiflora and Quercus virginiana, that were subjected to flood and control conditions in a greenhouse experiment.

Beyond single nucleotide polymorphisms (SNPs), gene presence/absence variation (PAV) plays a crucial role in elucidating species' genetic diversity, uncovering the genetic basis of key traits, and advancing molecular marker-assisted breeding in plants. In this study, we constructed a pangenome of Liriodendron based on 24 accessions. Comparative analysis with the reference genome revealed 116 Mb of non-reference sequences and obtained 32,773 genes, including 3,558 novel genes.

The STAY-GREEN (SGR) genes play pivotal roles in chlorophyll degradation across diverse plant species; however, their functions in the fast-growing tree Liriodendron tulipifera remain largely unknown. In this study, we isolated and characterized the LtSGR1 gene from L. tulipifera.

Tulip trees ( and ), members of the Magnolia family, are known for their distinctive morphology and ecological significance, but their chemical diversity remains understudied. In this study, we report the identification and characterization of an array of sesquiterpene lactones (SQLs) produced by . Through comprehensive chemical analysis, including high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy, we identified a series of STLs with distinct bioactivity profiles.
