2) Stomatal closure

气孔关闭
1.
The role of hydrogen peroxide(H2O2),nitro oxide(NO) and calcium(Ca2+) in stomatal closure of tobacco induced by elicitor PB90,a protein elicitor secreted by Phytophthora boehmeriae was investigated.
1nm o l/L激发子PB90可诱导野生型烟草Bel-W 3气孔关闭,且在相同条件下该激发子诱导反义抑制抗坏血酸过氧化物酶anti-APX烟草气孔关闭的孔径比野生型的更小;进一步药理学证明,抗氧化剂DTT和NADPH氧化酶抑制剂DPI(d ipheny-lene iodonium)、一氧化氮合酶(NO S)抑制剂L-NAM E、Ca2+螯合剂EGTA和Ca2+信号途径中CaM PKⅡ的竞争抑制剂KN93与磷脂酶C抑制剂U73122都能抵消PB90诱导气孔关闭的效应。

闭口孔型
closed pass
b ikou kongxing闭口孔型(elosed pass)札棍的棍缝:位于 帐…二J 闭口孔型孔型周边之外且有孔型顿口的孔型,如图所示。通常,在开廿孔型和闭口孔型中札制轧件,都可以获得同一种规格的产品,但闭口孔型对轧件侧边的加工比开口孔型好,因而产品的精度和力学性能都比较好。由于闭口孔型在轧辊上的切槽很深,降低了轧辊的强度,切槽车削加工也比较困难,轧件对孔型侧壁的磨损也较大。所以,一般在轧制异形断面型材时才采用闭口孔型。 (朱殿强)
