An actin starry night regulates seed size

Nature Plants, 2023
In Arabidopsis, the final size of the seed is determined early on during its development by the growth of a single multinucleate cell, the coenocytic endosperm. The endosperm arises from a second fertilization event, alongside the embryo, and dominates the onset of seed development while later nourishing and supporting embryo growth.

Seed Size Variation in Desmodium Paniculatum: I. Factors Affecting Seed Size

The Journal of Ecology, 1986
SUMMARY (1) In a population of Desmodium paniculatum seed weight varies by a factor of about four. Increase in temperature during the growth of the plants, reduces nutrient and water availability, and shortening of the photoperiod decreases the mean seed weight.

Granivore seed-size preferences

Seed Science Research, 2011
AbstractAlthough seed-size preference by granivores is relative to the sizes of seeds offered by researchers, preferences are often inappropriately discussed and interpreted as if they are for absolute seed sizes. Granivores often prefer relatively small seeds in forests and relatively large seeds in herbaceous communities, although the absolute size ...

Synthesis of Monodispersedly Sized ZnO Nanowires from Randomly Sized Seeds

Nano Letters, 2019
We demonstrate the facile, rational synthesis of monodispersedly sized zinc oxide (ZnO) nanowires from randomly sized seeds by hydrothermal growth. Uniformly shaped nanowire tips constructed in ammonia-dominated alkaline conditions serve as a foundation for the subsequent formation of the monodisperse nanowires.

The scaling of seed size

Journal of Ecology, 2008
Summary 1Rees & Venable (2007; Journal of Ecology, 95, 926–936) critically evaluated ideas of Moles et al. to explain the cross-species positive correlation between offspring size and adult size, arguing that they had misinterpreted the theoretical literature, and used cross-species patterns to constrain the evolution of life-histories.

Seed Sizing with Image Analysis

2004, Ottawa, Canada August 1 - 4, 2004, 2004
Seed size is an important grading factor in pulse grains. Seed processors and canning industry prefer shipments with minimal size variability to those with a wider range of seed distribution. Typically, seed size distribution of a batch of grains is determined by sieving a representative sample from a batch. Image analysis based seed sizing provides

Co-evolution of seed size and seed predation

Evolutionary Ecology, 1998
Using the evolutionarily stable strategy (ESS) approach in a model for the co-evolution of seed size and seed predation, I show that seed size variation within individual plants is favoured if there is a trade-off in the predator's attack rate for different seed sizes. A single seed size is not evolutionarily stable because a predator that is optimally

Evolutionary ecology of seed dormancy and seed size

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1996
The theoretical ideas underpinning the evolution of seed dormancy and seed mass are briefly reviewed. Comparative tests of these theoretical ideas are then presented; all tests use modern comparative methods to allow accurate, meaningful comparisons across species.

Seed size selection in heteromyids

Oecologia, 1978
The general conclusion of this paper is that heteromyids do not select seed sizes on the basis of their body size. My conclusion comes from the analysis of new data from central New Mexico, analysis of data in the literature on food habits of heteromyids, and a reanalysis of Brown and Lieberman (1973) and Brown (1975).
