Discovery of Regulatory Elements by a Computational Method for Phylogenetic Footprinting

open access: yes, 2002
Phylogenetic footprinting is a method for the discovery of regulatory elements in a set of orthologous regulatory regions from multiple species. It does so by identifying the best conserved motifs in those orthologous regions.

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

open access: yesAdvanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

The phylogenetic relationships of the gobioninae (Teleostei : Cyprinidae) inferred from mitochondrial cytochrome b gene sequences

open access: yes, 2006
The Gobioninae are a group of morphologically and ecologically diverse Eurasian freshwater cyprinid fishes. The intergeneric relationships of this group are unresolved and the possible monophyly of this subfamily remains to be established.

Natural Variation of COLD and CATECHINS REGULATOR 1 Coordinately Fine‐Tunes Cold Tolerance and Tea Quality in Tea Plants

open access: yesAdvanced Science, EarlyView.
Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

Single‐Cell Profiling Identifies SLC2A5‐Mediated Fructose Metabolism as a Vulnerability in Primary CNS Lymphoma

open access: yesAdvanced Science, EarlyView.
Glucose deprivation in the primary CNS lymphoma (PCNSL) tumor microenvironment drives SLC2A5 (encoding GLUT5)‐dependent fructose metabolism in tumor cells, while hypoxia induces HIF‐mediated SLC2A5 expression in tumor‐supportive macrophages, revealing SLC2A5‐driven fructose utilization as a shared and targetable metabolic vulnerability across malignant

Amidase‐Catalyzed Desorption of CO2 Captured in Aqueous Monoethanolamine (MEA) Solutions

open access: yesAngewandte Chemie, EarlyView.
CO2 is captured in aqueous monoethanolamine (MEA) sorbents as carbamate and bicarbonate/carbonate. The subsequent desorption for storage or utilization is energy‐intensive, and this is a major impediment to industrial carbon dioxide removal (CDR) processes. The desorption process can be promoted by enzymes that catalyze the dissociation of distinct CO2‐

Phylogenetic relationships among isolates of Cryptosporidium: evidence for several new species

open access: yes, 1999
Isolates of Cryptosporidium were characterized using nucleotide sequence analysis of the 18S rRNA and dihydrofolate reductase genes and also random-amplified polymorphic DNA analysis.

INFERENCE OF GENE COEVOLUTION BASED ON PHYLOGENETIC PROFILES

open access: yes, 2022
Phylogenetic profiles, which summarize the presence and absence patterns of genes in a set of genomes, can be used to identify genes that have correlated evolutionary histories.

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress

open access: yesAdvanced Science, EarlyView.
Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.

Phylogenetic relationships of coconut phytoplasmas and the development of specific oligonucleotide PCR primers

open access: yes, 1998
Using the polymerase chain reaction the 16S rRNA genes and the 16S-23S spacer regions of phytoplasmas associated with lethal decline diseases of coconut palm (Cocos nucifera), were amplified from infected plants from Florida and the Yucatan region in ...
