R

Fifth letter of a Nasdaq stock symbol specifying that the stock has rights.

R

A symbol appearing next to a stock listed on NASDAQ indicating that the share being traded comes with a right. All NASDAQ listings use a four letter abbreviation; if an R follows the abbreviation this indicates that the share has rights attached to it.

1. Used in the dividend column of stock transaction tables in newspapers to indicate the amount of dividends declared or paid in the preceding 12 months plus a stock dividend: PE Cp .25r.
2. Used in mutual fund transaction tables in newspapers to indicate funds that levy a deferred sales charge when shares are sold: IDS Inc r.
3. Used in bond transaction tables in newspapers to indicate a registered security. Although most bonds are registered, this symbol is used when a distinction is necessary, as when a bond trades in registered and in bearer form: NoPac 3.47r.

The goals of this study were to (i) estimate B chromosome polymorphisms based on their occurrence, morphology, and frequency in maize landraces from Southwest China, (ii) provide evidence for the evolution of maize landraces from Southwest China, and (iii) infer the geographical origin of landraces in southwest China.
Ward and colleagues had previously shown that two Y chromosome genes--Sry and Eif2s3y--are crucial for male mouse development.
Instead, they showed that the low variation can be explained by intense natural selection, that is, a strong evolutionary pressure to weed out bad mutations that ended up trimming the chromosome down to its essentials.
