Three‐dimensional X‐ray‐computed tomography of 3300‐ to 6000‐year‐old Citrullus seeds from Libya and Egypt compared to extant seeds throws doubts on species assignments

open access: yesPlants, People, Planet, 2021
Societal Impact Statement The watermelon (Citrullus lanatus subsp. vulgaris) is among the world's most important fruit crops. We here use C‐14 dating and morphometric analysis to test whether ancient seeds can be identified to species level, which would ...

Brassinosteroid Regulates Seed Size and Shape in Arabidopsis [PDF]

open access: yesPlant Physiology, 2013
Seed development is important for agriculture productivity. We demonstrate that brassinosteroid (BR) plays crucial roles in determining the size, mass, and shape of Arabidopsis (Arabidopsis thaliana) seeds. The seeds of the BR-deficient mutant de-etiolated2 (det2) are smaller and less elongated than those of wild-type plants due to a decreased seed ...

Seed Shape Quantification in the Malvaceae Reveals Cardioid-Shaped Seeds Predominantly in Herbs

open access: yesBotanica, 2019
AbstractSeed shape in the Malvaceae and other families of the order Malvales was investigated. Seed shape was quantified by comparison with the cardioid. The J index is the percent similarity between both images, the seed and the cardioid, and similarity is considered in cases where the J index is over 90.

Seed Architecture Shapes Embryo Metabolism in Oilseed Rape   [PDF]

open access: yesThe Plant Cell, 2013
Abstract Constrained to develop within the seed, the plant embryo must adapt its shape and size to fit the space available. Here, we demonstrate how this adjustment shapes metabolism of photosynthetic embryo. Noninvasive NMR-based imaging of the developing oilseed rape (Brassica napus) seed illustrates that, following embryo bending ...

Seed Morphology in Silene Based on Geometric Models

open access: yesPlants, 2020
Seed description in morphology is often based on adjectives such as “spherical”, “globular”, or “reniform”, but this does not provide a quantitative method.

Fruit shape loci sun, ovate, fs8.1 and their interactions affect seed size and shape in tomato

open access: yesFrontiers in Plant Science, 2023
Seed size and shape are not only critical for plant reproduction and dispersal, but also important agronomic traits. Tomato fruit shape loci sun, ovate and fs8.1 regulate the morphology of fruit, flower, leaf and stem, and recently their functions in ...

A Seed Shape Mutant of Arabidopsis That Is Affected in Integument Development. [PDF]

open access: yesThe Plant Cell, 1994
A seed shape mutant of Arabidopsis was isolated from an ethyl methanesulfonate-treated population. Genetic analysis revealed that the heart-shaped phenotype was maternally inherited, showing that this is a testa mutant. This indicated the importance of the testa for the determination of the seed shape. This recessive aberrant testa shape (ats) gene was

How Seeds Shape Our World

open access: yesFrontiers for Young Minds, 2023
Have you eaten bread or rice recently? Or maybe something with oil in it? If you said yes, then you were likely eating foods made from seeds. Seeds are an important food source for humans and animals, and they make up our grains, lentils, nuts, and cooking oils.
