Regulation of Transpiration by Stomata02:04

Regulation of Transpiration by Stomata

31.6K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Asexual Reproduction

37.8K
Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Seed Structure and Early Development of the Sporophyte

31.5K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Basic Plant Anatomy: Roots, Stems, and Leaves

The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.

Epiphytes, Parasites, and Carnivores

17.0K
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Summary

This study reveals that Apocynaceae plants possess stipules, leaf structures that develop into colleters. This finding reinterprets stipule evolution within the Gentianales order.

Area of Science:

  • Plant morphology and evolution
  • Developmental botany
  • Gentianales systematics

Background:

  • Stipules are diverse leaf structures, with interpetiolar stipules considered characteristic of Rubiaceae in Gentianales.
  • Previous literature suggested stipule presence in other families, prompting further investigation.

Purpose of the Study:

  • To investigate the presence of reduced or modified stipules in Apocynaceae through developmental analysis.
  • To understand the evolutionary implications of stipule presence/absence in Gentianales.

Main Methods:

  • Analysis of shoot apices from 12 Apocynaceae genera using light and scanning electron microscopy.
  • Comparative analysis with a representative species from Rubiaceae.

Main Results:

  • Leaf primordia in Apocynaceae consistently form basal lateral expansions (stipules) that develop into colleters in 11 of 12 genera.
  • Basal Apocynaceae genera exhibit stipules modified into lateral colleters.
  • Derived Apocynaceae species show interpetiolar stipules that fuse to form a sheathing structure, from which interpetiolar colleters arise.

Conclusions:

  • Apocynaceae is confirmed as a stipulate family, with stipules modified into colleters.
  • The apparent absence of stipules in some Apocynaceae species is likely due to secondary loss.
  • This study significantly alters the understanding of stipule evolution within the Gentianales order.
