The spatial and temporal dynamics of diversification in Tylecodon, Cotyledon and Adromischus (Crassulaceae) in southern Africa
… hypothesis was generated for Tylecodon, Cotyledon and Adromischus in order to estimate the timing and spatial dynamics of diversification across these three southern African genera. These data were used to investigate the correlates and consequences of adaptations to extreme aridity and …

The Pharmacological actions of Plants of the Genera Cotyledon and Crassula, N.O. Crassulaceae, with other Papers
… (Nenta, Kraamsiekte, cerebrospinal meningitis, Cotyledonosis) has been recognised in South Africa for ma.ny years. It appears in arid parts of the Cape Province, and affects animals which have ingested certain members of the genus Cotyledon (N.O. Crassulaceae).

Light Transmission Properties of Lentil (Lens culinaris Medik.) Seed Coat and Effect of Light Exposure on Cotyledon Quality
Cotyledon color is one of the most important quality criteria in the lentil market because the color may correlate well with other quality attributes. Therefore, cotyledon color is an important quality criterion in lentil breeding programs. The objectives of this work were to investigate the …

Regeneration and germination of cucumber seeds in vitro and a study of delayed flowering gene (df)
… L.) lines were studied for germination and cotyledon regeneration. Depending on cultivars, seeds stored at 68$\sp\circ$F and 38% relative humidity remained 40 to 90% viable for 13 years. Seeds older than that were nonviable. It was also found that removing 1/4 cotyledon from fresh cucumber …

The importance of cotyledon functional morphology and patterns of seed reserve utilization for the physiological ecology of neotropical tree seedlings
… makeup of seed, and functional morphology of cotyledons are three traits that together determine patterns of seed reserve utilization by seedlings during their critical establishment stage. The main objective of this thesis is to examine how these traits differentiate the patterns of seedling …

The Analysis of Two Receptor-like Kinases Redundantly Required for Pattern Formation during Arabidopsis Embryogenesis
… also have overlapping functions required for cotyledon primordia initiation during Arabidopsis embryogenesis. Genetic analyses indicate that cotyledon initiation is sensitive to TOAD2 gene dosage in an rpk1 background. Analysis of cell-specific markers suggest that RPK1 and TOAD2 are primarily …

Fungi associated with northern red oak (Quercus rubra ) acorns
… what fungi are associated with and cause cotyledon discoloration of northern red oak acorns. The field study determined that simulated small mammal notching, surface sowing, time, and site all play a significant role in the amount of cotyledon discoloration in acorns as well as the number …

Feto-placental vascular structure and function: comparison of within and between species variations
… branching patterns within a human placental cotyledon. Micro-computerised tomography (Micro-CT) imaging protocols were developed, allowing imaging at 5µm pixel resolution and extraction of vasculature down to vessels of approximately 45µm diameter. Branching analysis showed that the …

COMPARATIVE EFFECTS OF GIBBERELLIC ACID AND N(6)-BENZYLADENINE ON GROWTH AND DEVELOPMENT OF DWARF WATERMELON SEEDLINGS
… hypocotyl length was increased expansion of the cotyledons and inhibition of root growth. A study on dry matter partitioning indicated that both hormones caused a preferential mobilization of metabolites from the cotyledons to the hypocotyl at an expense to roots. However, in comparison to …

De novo morphogenesis on tomato thin cell layers and variation for genetic recombination among plantlets regenerated from tissue culture
… produced on thin cell layer explants than on cotyledon calli, or micropropagated shoot tips. Genetic recombination rates and map distances were compared among hybrid plants grown in the greenhouse and regenerated from the aforementioned tissue culture systems. Increased recombination rates and …

Detection of freeze damage in Virginia peanuts (Arachis hypogaea L.) by conductivity, tetrazolium, dipicrylamine, and visual tests
… leakage from cells onto the surface of the cotyledon. A visual test was developed based on differences in glossiness of the flat surface of the peanut cotyledon. A freezing apparatus was designed and operated so that peanuts could be cooled at a slow, even rate to a series of low …

Quality characteristics of Australian chickpeas (Cicer arietinum L.) for food usage
… composition of desi dhal (dry, dehusked split cotyledon) was measured and compared to whole seed.

Transcript Profiling of Soybean Seed Development From Fertilization to Maturity
… (Jones 2004) over five stages of soybean cotyledon development from mid-maturation through desiccation using microarrays containing more than 27,000 soybean cDNAs was reevaluated using a p-value filter. The expression level changes of selected genes were also retested in these older stages …

A revision of Otholobium C.H. Stirton (Papilionoideae, Leguminosae)
… had been widely assumed: new characters included cotyledon type, arrangement of the embryo and radicle in the seed, seed shape, fruit morphology, chromosome numbers, petiolar anatomy, root architecture, nodule type, inflorescence architecture, 6AH-pterocarpan and 6a-hydroxy analogue chemistry, …
