SACs are those genes with expression up-regulated during leaf senescence. Class I SACs are expressed only during senescence (senescence-specific). Class II SAGs have a basal level of expression during early leaf development, but this level increases during senescence.
Which Sample Rate to use. 44.1 kHz. 44.1 kHz (44100 Hz) is the sampling rate of audio CDs giving a 20 kHz maximum frequency. 20 kHz is the highest frequency generally audible by humans, so making 44.1 kHz the logical choice for most audio material.
For example, if you set a clip to play at 50% speed, it will play back at half speed. 25% would be one quarter speed. Adobe Premiere Pro allows you to set playback speeds up to two decimal places, so you could have 27.13% if you want. Letâs explore this technique. In the Project panel, load the sequence 02 Speed/Duration. Right-click the Eagle_Walk clip, and choose Speed/Duration from the context menu.
