Ecological Isolation Maintains the Species Boundaries Between Two Sympatric <i>Cycas</i> From Southwest China. [PDF]

Ecol Evol
The study reveals that sympatric Cycas species (C. pectinata and C. simplicipinna) maintain strict species boundaries without hybridization, driven by reproductive isolation mechanisms (divergent coning times and pollinator specificity) and ecological niche differentiation (habitat preferences, soil pH differences).

NGATHA carpel development genes evolved in the common ancestor of seed plants. [PDF]

Plant J
SUMMARY The evolution of the carpel, the defining feature of angiosperms, remains a fundamental question in plant biology. Understanding how this organ originated is crucial because it underpins the reproductive success and diversity of flowering plants.

The Cycas genome and the early evolution of seed plants

Nature Plants, 2022
Cycads represent one of the most ancient lineages of living seed plants. Identifying genomic features uniquely shared by cycads and other extant seed plants, but not non-seed-producing plants, may shed light on the origin of key innovations, as well as ...

Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]

FEBS J
Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

The complete mitochondrial genome of Cycas debaoensis revealed unexpected static evolution in gymnosperm species.

PLoS ONE, 2021
Mitochondrial genomes of vascular plants are well known for their liability in architecture evolution. However, the evolutionary features of mitogenomes at intra-generic level are seldom studied in vascular plants, especially among gymnosperms.

Lectotypification of Cycas debaoensis (Cycadaceae) [PDF]

PhytoKeys, 2022
The type of Cycas debaoensis Y.C.Zhong &amp; C.J.Chen (Y.C.Zhong 8762) consists of nine duplicates in PE. Our new investigation of the type collection suggests that the type includes at least two different gatherings which should be considered as ...

Anti-Biofilm and Antibacterial Activities of Cycas media R. Br Secondary Metabolites: In Silico, In Vitro, and In Vivo Approaches

Antibiotics, 2022
Enterococcus species possess many virulence factors that have an essential role in exacerbating the infections caused by them. The current study aimed to evaluate the effect of the secondary metabolites ginkgetin (GINK) and sotetsuflavone (SOTE ...

Root System Radius of Three Cycas Species

HortScience, 2022
Knowledge about the position of tree roots is needed to understand tree biology and inform management decisions. Cycad species produce pachycaul stems and are not represented in the published studies on the relationships between aboveground tree traits ...
