Time increases from top to bottom in the figure, so contours that are oriented from upper-left to lower-right represent movement from west to east. The Madden–Julian oscillation ( MJO ) is the largest element of the intraseasonal (30- to 90-day) variability in the tropical atmosphere.
European interest began when Spanish conquistadors returned with pineapple, which became so popular as an exotic food that the image of the pineapple was adapted into European art and sculpture. In 1776, the species Guzmania lingulata was introduced to Europe, causing a sensation among gardeners unfamiliar with such a plant.
A Pineapple Express storm hit the state from 1 to 2 February 2024, before moving over the United States and settling over the I-25 corridor in Colorado, where heavy snow fell. Another one hit 3 February and last until 5 February, with the National Weather Service calling it "potentially life-threatening."
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
The naturalist and author Richard Fitter recorded the First Flowering Date (FFD) of 557 species of British flowering plants in Oxfordshire between about 1954 and 1990. Writing in Science in 2002, Richard Fitter and his son Alistair Fitter found that "the average FFD of 385 British plant species has advanced by 4.5 days during the past decade ...
Florigen is a systemically mobile signal that is synthesized in leaves and the transported via the phloem to the shoot apical meristem (SAM) where it initiates flowering. [1] [5]: 488 In Arabidopsis, the FLOWERING LOCUS T (FT) genes encode for the flowering hormone and in rice the hormone is encoded by Hd3a genes thereby making these genes ...
There's just one more Reagan family dinner left on the table. After 14 seasons, Blue Bloods will air its final episode Friday, Dec. 13. The CBS procedural will draw to a close with its 293rd ...
In order to explain the floral morphology of the Liliaceae, van Tunen et al. proposed a modified ABC model in 1993. This model suggests that class B genes are not only expressed in verticils 2 and 3, but also in 1. It therefore follows that the organs of verticils 1 and 2 express class A and B genes and this is how they have a petaloid structure.
