Winter greens Winter greens Winter greens are green leaved vegetables, closely related to the cabbage, that are seasonably available in winter. Common vegetables described as winter greens are chard, collards, rapini, and kale. William Morgan classed Brussels sprouts, savoy cabbages and several varieties of kale as winter greens. Morgan grew these vegetables and compared their hardiness, identifying which species were most suitable for growing through cold winters. He presented his findings to the Horticultural Society of London in 1818. Late season crops "from October through December, a gardener can easily maintain and eat bok choy, pak choy (the purple pak choy is
BOK (gene) of Bok to its interacting partners seems to be mediated by its BH3 domain. The splice variant Bok-S lacks this domain and is unable to form heterodimers with other proteins of the Bcl-2 family. In yeast two-hybrid experiments, Bok was found to interact with the anti-apoptotic proteins Mcl-1, BHRF-1, and Bfl-1. However, interactions with other anti-apoptotic proteins such as Bcl-2, Bcl-xL, and Bcl-w were not detectable (1). Later studies aimed at confirming an interaction between Bok and pro-apoptotic Bak or Bax but were not successful. Accordingly, coexpression of anti-apoptotic proteins such as Mcl-1 suppresses apoptosis induced by Bok overexpression. Consistent
