EFFECT OF NITROGEN SOURCES AND GIBBERELLIC ACID RATES ON GROWTH AND CHEMICAL COMPOSITION OF CYCAS PLANTS (Cycas revoluta THUMB.) [PDF]

open access: yesJournal of Plant Production, 2005
The present work was designed to study the effect of different nitrogen sources (ammonium nitrate, ammonium sulphate and urea) and gibberellic acid rates (0, 250 and 500 p.p.m. /plant) on growth of Cycas revoluta seedlings, that were one-year-old, during

Metabologenomic Hallmark‐Based Discovery of Bacterial Thioamides as a New Lead against Drug‐Resistant Pancreatic Cancer

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
A targeted metabologenomic strategy integrating genomic and metabolomic hallmarks enabled the discovery of two new thioamides, thiogochangamides A and B, from bacteria. Their absolute configurations, previously unresolved within the thioviridamide family, were fully assigned through various chemical derivatizations and computational analysis ...

Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Cyclic peptides occupy a structurally dynamic region of chemical space, where function often arises from ensembles rather than a single dominant fold. Closed backbones, frequent N‐methylation, heteroatoms, unnatural amino acids, and a strong propensity for metal coordination create dense conformational and coordination landscapes that ...

Divergence With Gene Flow and Contrasting Population Size Blur the Species Boundary in Cycas Sect. Asiorientales, as Inferred From Morphology and RAD-Seq Data

open access: yesFrontiers in Plant Science, 2022
The divergence process of incipient species is fascinating but elusive by incomplete lineage sorting or gene flow. Species delimitation is also challenging among those morphologically similar allopatric species, especially when lacking comprehensive data.

The Origin and Diversification of Turmerics (Curcuma L.: Zingiberaceae) in Paleotropical Biodiversity Hotspots: The Role of Ancient Hybridisation and Historical Climate Change

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 5, May 2026.
ABSTRACT Aim To investigate the ecological and evolutionary mechanisms driving biodiversity in the Indo‐Malayan hotspots, with a particular focus on the roles of ancient hybridisation and historical climate in shaping species diversity. Location The Indo‐Malayan realm, particularly the Western Ghats‐Sri Lanka and Indo‐Burma biodiversity hotspots.

Tracking the Dynamics of human Colonisation and Adaptation in Central Vanuatu: Preliminary Results From Excavation and Survey at Pangpang, East Efate

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 221-236, April 2026.
ABSTRACT In October 2022 an extensive archaeological landscape was identified by staff of the Vanuatu Cultural Centre at Pangpang on the east coast of Efate Island in central Vanuatu. It included midden deposits on the banks of the Pangpang River near the sea at Forari Bay where Lapita and Early Erueti‐style pottery sherds were recovered.
