Light Acquisition02:16

Light Acquisition

9.3K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Gene Flow02:39

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Transgenic Plants02:50

Transgenic Plants

8.4K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Plant Breeding and Biotechnology

21.4K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Non-vascular Seedless Plants

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

Area of Science:

  • Ecology
  • Botany
  • Biodiversity Science

Background:

  • Biological invasions pose significant ecological and economic challenges globally.
  • Understanding the patterns and drivers of plant naturalization is crucial for conservation and management.
  • Existing databases require regular updates to reflect new data and taxonomic changes.

Purpose of the Study:

  • To present GloNAF 2.0, an updated and expanded global database of alien naturalized vascular plants.
  • To detail the major improvements in taxonomic standardization, data completeness, and geographic coverage.
  • To align the GloNAF database with FAIR data principles for enhanced accessibility and reusability.

Main Methods:

  • Compilation and curation of vascular plant inventories from global geographic regions.
  • Standardization of taxonomic names using the World Checklist of Vascular Plants (WCVP).
  • Inclusion of new records and removal of outdated data to enhance database accuracy and scope.

Main Results:

  • GloNAF 2.0 contains 16,429 taxa, a substantial increase from previous versions.
  • The database now covers 31% more geographic regions compared to GloNAF 1.2.
  • Significant additions of 117,229 new records, increasing naturalized taxa by 26%.

Conclusions:

  • GloNAF 2.0 is a comprehensive and accessible resource for studying biological invasions.
  • The updated database facilitates research on the drivers and consequences of plant naturalization.
  • Adherence to FAIR data principles ensures the long-term utility and impact of the GloNAF dataset.
