What is Molecular Systematics of Gesneriaceae Allies?

Molecular Systematics of Gesneriaceae Allies uses plastid and nuclear DNA markers to resolve phylogenetic relationships and circumscriptions among Lamiales families related to Gesneriaceae, with divergence dating calibrated by fossils.

This subtopic employs plastid genes like atpB, rbcL, and full plastomes alongside nuclear markers to reconstruct phylogenies of Lamiales. Key studies include plastid phylogenomics of Lamiaceae (Li et al., 2016, 231 citations; Zhao et al., 2021, 271 citations). Over 10 papers from the list address plastid-based systematics in allied families, refining classifications.

Key Challenges

Why It Matters

Accurate phylogenies guide biodiversity conservation by identifying monophyletic groups for protection in Lamiales hotspots. Li et al. (2016) reclassified Lamiaceae subfamilies using 231 plastid phylogenies, impacting herbarium curation. Zhao et al. (2021) updated Lamiaceae tribes with plastome data, aiding priority setting for endangered Gesneriaceae allies. Ruhfel et al. (2014) provided a 360-plastome backbone for Viridiplantae, enabling fossil-calibrated dating of Lamiales divergences.

Key Research Challenges

Plastid-nuclear discordance

Incongruence between plastid and nuclear trees challenges Lamiales circumscriptions. Li et al. (2016) noted cytonuclear conflicts in Lamiaceae using atpB-rbcL data. Resolving requires multi-locus datasets (Ruhfel et al., 2014).

Sparse Gesneriaceae ally sampling

Limited taxon sampling hinders robust ally phylogenies in Lamiales. Zhao et al. (2021) sampled 200+ plastomes for Lamiaceae tribes but underrepresented Gesneriaceae relatives. Dense sampling via universal primers is needed (Dong et al., 2013).

Fossil calibration accuracy

Uncertain fossil placements bias divergence dates for Lamiales. Särkinen et al. (2013) dated Solanaceae with fossil-calibrated trees, highlighting calibration sensitivity. Standardized fossil protocols are required for Gesneriaceae allies.
