Growth and morphogenesis at the vegetative shoot apex of Anagallis arvensis L. (1/5)
A non-destructive replica method and a 3-D reconstruction algorithm are used to analyse the geometry and expansion of the shoot apex surface. Surface expansion in the central zone of the apex is slow and nearly isotropic while surface expansion in the peripheral zone is more intense and more anisotropic. Within the peripheral zone, the expansion rate, expansion anisotropy, and the direction of maximal expansion vary according to the age of adjacent leaf primordia. For each plastochron, this pattern of expansion is rotated around the apex by the Fibonacci angle. Early leaf primordium development is divided into four stages: bulging, lateral expansion, separation, and bending. These stages differ in their geometry and expansion pattern. At the bulging stage, the site of primordium initiation shows an intensified expansion that is nearly isotropic. The following stages develop sharp meridional gradients of expansion rates and anisotropy. The adaxial primordium boundary inferred from the surface curvature is shifting until the separation stage, when a crease develops between the primordium and the apex dome. The cells forming the crease, i.e. the future leaf axil, expand along the axil and contract across it. Thus they are arrested in this unique position.

BACKGROUND AND AIMS: By using the technique of replicas of a developing apex it is possible to obtain a direct measure of phyllotactic parameters (plastochrone and platochronic ratio) involved in the initiation of two successive primordia at the level of the SAM. The goal of this study is to compare, in a real time setting, the value of phyllotactic parameters in distichous systems using Begonia as a case study, with the value of the same parameters in spiral phyllotactic systems. METHODS: To determine the real-time sequence of events at the level of the SAM, replicas were made of the developing apex at different intervals using previously described techniques. Impression moulds were made at 24-h intervals. The following phyllotactic parameters were measured: plastochrone, angle of divergence, plastochrone ratio and ratio between the diameter of the leaf and the apex. RESULTS: The time between the appearance of two successive leaves is 15-20 d. The average value of the plastochrone ratio (R) is 1.3, and the ratio of the leaf to the diameter of the apex (Gamma) is 2.5. The angle of divergence varies from 165 masculine to 180 masculine. The speed of advection of the primordium from the apex, varies from 0.28 to 0.37 microm d(-1). CONCLUSIONS: The speed of advection of primordia in Begonia is lower than that of Anagalis. This is not in accordance with theoretical simulations that predict the opposite. In Begonia, the plastochrone ratio does not reflect the real time of appearance of two successive primordia. The time separating the appearance of two primordia is not directly related to the distance of these two primordia from the centre of the apex but is related instead to the enlargement of leaves.

A new skeleton of an O-heteroside natural substance named zinolol, the first representative of a new class of aminated hydroxyhydroquinone, has been isolated from the whole plant Anagallis monelli. Its structure has been established by one and two dimensional NMR spectroscopic procedures. Antioxidant, mutagenic, antimutagenic activities were realised and positive results were recorded.

(+info)"Anagallis" is a genus name that refers to a group of flowering plants commonly known as "pimpernels." These plants belong to the primrose family (Primulaceae) and are found in various parts of the world, including Europe, Asia, Africa, and America. The name "Anagallis" comes from the Greek word "anagelao," which means "to laugh," possibly referring to the smiling expression of the flowers.
There are around 20-30 species of Anagallis, some of which have medicinal uses. For example, Anagallis arvensis (scarlet pimpernel) has been used in traditional medicine for treating various ailments such as skin conditions, eye problems, and respiratory issues. However, it is important to note that the use of these plants as medicine should be done under the guidance of a qualified healthcare professional, as they can also have toxic effects if not used properly.

- Anagallis is a genus of about 20-25 species of flowering plants in the family Primulaceae, commonly called pimpernel. (wikipedia.org)
- In the APG III system, published in 2009, Primulaceae is expanded to include Myrsinaceae, thus Anagallis is back in Primulaceae again. (wikipedia.org)

Lysimachia2
- Another study by Ulrika Manns and Arne A. Anderberg (2005), based on molecular phylogeny, states that Anagallis in its present circumscription is paraphyletic and should also include in its clade the small genera Asterolinon and Pelletiera, as well as two Lysimachia species (Lysimachia nemorum and Lysimachia serpyllifolia). (wikipedia.org)
- While Anagallis is clearly polyphyletic, we are retaining it for the time being rather than 'watering down' Lysimachia as we await clarity from additional studies. (vaplantatlas.org)
