Acer rubrum ‘Autumn Spire’

Early Autumn Senescence in Red Maple (Acer rubrum L.) Is Associated with High Leaf Anthocyanin Content

Several theories exist about the role of anthocyanins in senescing leaves. To elucidate factors contributing to variation in autumn leaf anthocyanin contents among individual trees, we analysed anthocyanins and other leaf traits in 27 individuals of red maple (Acer rubrum L.) over two growing seasons in the context of timing of leaf senescence. Red maple usually turns bright red in the autumn, ...

Identification of Acer rubrum using amplified fragment length polymorphism.

Amplified fragment length polymorphism (AFLP) analysis of botanical forensic evidence provides a means of obtaining a reproducible DNA profile in a relatively short period of time in species for which no sequence information is available. AFLP profiles were obtained for 40 Acer rubrum trees. Leaf material from five additional species was also typed. Genomic DNA was isolated using the DNeasy Pla...

Pharmacy research at URI: mining red maple (Acer rubrum) trees for novel therapeutics to manage diabetes.

Characterization of Rubisco activase from thermally contrasting genotypes of Acer rubrum (Aceraceae).

The lability of Rubisco activase function is thought to have a major role in the decline of leaf photosynthesis under moderate heat (<35°C). To investigate this further, we characterized Rubisco activase and explored its role in the previously demonstrated thermal acclimation and inhibition of two genotypes of Acer rubrum originally collected from Florida (FL) and Minnesota (MN). When plants we...

The benefits of seed banking for red maple (Acer rubrum): maximizing seedling recruitment

Seed banking is assumed to be unimportant for temperate trees, because their seeds are short-lived in soils. However, even short-term seed banking could increase recruitment and affect population dynamics of seed-banking trees. To investigate this possibility, we examined early life-history stages of red maple (Acer rubrum L.), an abundant seed-banking tree in eastern forests. We found that see...
