Previous investigators have identified strong positive relationships between genome size and seed mass within species, and across species from the same genus and family. Here, we make the first broad-scale quantification of this relationship, using data for 1222 species, from 139 families and 48 orders. We analyzed the relationship between genome size and seed mass using a statistical framework...

Seed development in Arabidopsis thaliana undergoes an initial phase of endosperm proliferation followed by a second phase in which the embryo grows at the expense of the endosperm. As mature seed size is largely attained during the initial phase, seed size is coordinately determined by the growth of the maternal ovule, endosperm, and embryo. Here, we identify SHORT HYPOCOTYL UNDER BLUE1 (SHB1) ...

Australian Acacia are invasive in many parts of the world. Despite significant mechanical and biological efforts to control their invasion and spread, soil-stored seed banks prevent their effective and sustained removal. In response South Africa has had a strong focus on employing seed reducing biological control agents to deal with Australian Acacia invasion, a programme that is considered as ...

Chickpea is valued for its nutritive seed composition which is high in protein content and used increasingly as a substitute for animal protein. High quality seed has the potential to attract premium prices. Hence, the breeding of desirable quality traits, including seed size for desi and kabuli-types, is of major importance. For this, two RIL populations derived from intraspecific crosses of a...

Explaining large-scale patterns of variation in body size has been considered a central question in ecology and evolutionary biology because several life-history traits are directly linked to body size. For ectothermic organisms, little is known about what processes influence geographic variation in body size. Changes in body size and sexual size dimorphism (SSD) have been associated with envir...

Shahin, M.A. and Symons, S.J. 2005. Seed sizing from images of non-singulated grain samples. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 47: 3.49 3.55. Image analysis is a strong candidate for developing automated measurement systems for seed sizing. A unique image analysis (IA) based approach to measuring seed size from non-singulated samples is presented in this paper. ...

Seed development of flowering plant is a complicated process controlled by a signal network. Double fertilization generates 2 zygotic products (embryo and endosperm). Embryo gives rise to a daughter plant while endosperm provides nutrients for embryo during embryogenesis and germination. Seed coat differentiates from maternally derived integument and encloses embryo and endosperm. Seed size/mas...
