Eucheumatopsis Seaweed Molecular, Chemical, and Morphological Data from Yucatán, Mexico

Molecular, chemical, and morphological data for the seaweed species Eucheumatopsis isiformis, collected from March to November 2022 in Yucatán, Mexico, with a comparison specimen from Florida, USA. The dataset includes gene sequencing for haplotype construction, carrageenan yield and sulfate content measurements, and morphological characterizations. It was authored by Monserrat López-Yllescas and is available under a CC-BY-4.0 license.

Use Cases

• Construct phylogenetic trees based on cox1, rbcL, and RuBisCo spacer gene sequencing data.
• Analyze carrageenan yield and sulfate content variation between native and alkali-treated seaweed samples.
• Compare morphological characteristics of Eucheumatopsis isiformis morphotypes from different locations.
• Study the relationship between genetic haplotype and biochemical properties like carrageenan content.

Strengths

• Includes multiple data types: molecular sequences, chemical assays, and morphological descriptions.
• Provides temporal context with samples collected from March to November 2022.
• Offers a geographic comparison with a specimen from Florida, USA.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 1.4 MB size suggests a relatively small dataset.
