Vitis

Vitis (grapevines) is a genus of about 60 species of vining plants in the flowering plant family Vitaceae. The genus is made up of species predominantly from the Northern hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine. The study and cultivation of grapevines is called viticulture.

All vines share the same basic, physiological features. The roots anchor the vine to the soil and serve as the conduit where nutrients and water from the soil are absorbed. Along with the trunk or "permanent wood" features, the roots also serve as storage reserve of carbohydrates which the vine can use for energy in the winter after the leaves have fallen and are no longer conducting photosynthesis. The function of photosynthesis in the grapevine is to produce glucose which can be combined with other molecules to form larger carbohydrates (such as cellulose) that can be used to create other structures in the vine, energy reserves for the plant and, for fruiting grapevines, can be concentrated in grape berries which contain the reproductive seeds of the vine and are more attractive to birds and other animals.

Grapevine (gossip)

To hear something through the grapevine is to learn of something informally and unofficially by means of gossip or rumor.

The usual implication is that the information was passed person to person by word of mouth, perhaps in a confidential manner among friends or colleagues. It can also imply an overheard conversation or anonymous sources of information. For instance "I heard through the grapevine that Brad was getting fired."

Etymology

In his autobiography Up From Slavery, Booker T. Washington says that slaves in the South kept up-to-date on current events by "what was termed the 'grape-vine' telegraph."

However, the New York Public Library contests that the phrase derives from the infamous Grapevine Tavern in New York City's Greenwich Village. During the Civil War it "...was a popular hangout of Union officers and Confederate spies... It was the ideal place to get news and information, or in the case of spies and politicians, the ideal place to spread rumors and gossip, leading to the popular phrase 'heard it through the grapevine'."
