CAX(Ca^(2+)/H^(+)exchanger antiporter)是一类重要的阳离子转运蛋白,在植物生长发育和抵抗非生物胁迫中至关重要。通过生物信息学分析的方法,从欧洲葡萄中共鉴定出5个VvCAX基因,根据其在染色体上的位置依次命名为VvCAX1—VvCAX5,进行了包括理化性质、二级结构、三级结构、跨膜结构域、基因结构、保守基序、系统进化树等分析。结果表明,VvCAX基因家族成员均为疏水蛋白,主要定位于质膜和液泡,包含10~11个跨膜结构域和4个典型的功能域,α-螺旋和无规则卷曲在二级结构中占据主要位置,所有成员三级结构非常相似且均为单体。系统发育分析将VvCAX分为2个亚家族,同一亚家族的VvCAX结构相似,不同亚家族VvCAX的保守基序有差异,且7对VvCAX基因在进化过程中发生了基因的片段复制事件。VvCAX的互作蛋白主要与钙离子转运、钙离子通道和离子转运相关。上游调控因子和启动子顺式作用元件分析结果表明,VvCAX基因可能通过MYB、ERF等转录因子的调控参与激素和胁迫响应,这一推论经表达模式分析得到了验证。通过不同胁迫下的表达分析发现,所有VvCAX基因的表达水平均受ABA的影响,ⅠA亚家族的成员响应创伤、霜霉菌、干旱和低温,而ⅠB亚家族的成员主要与高温有关,ⅠA亚家族的VvCAX基因更有研究价值。

【目的】探明不同葡萄品种的耐弱光、抗高温特点,为选择其合适的栽培模式提供理论支持。【方法】以1年生阳光玫瑰、瑞都红玉、浪漫红颜等8个品种的葡萄植株为试验材料,利用便携式光合速率测定仪测定不同品种成熟叶片的光响应曲线及在大棚自然条件、大棚遮阴条件和大棚高温条件下的净光合速率(Pn)日变化。【结果】8个葡萄品种的Pn随光量子通量密度的增强表现出先升高后趋于稳定的变化趋势,由光响应曲线计算得到的光补偿点(LCP)、暗呼吸速率(Rd)、表观量子效率(AQY)、光饱和点(LSP)和最大净光合速率(Pm)能够较好地反映不同葡萄品种在弱光和强光条件下的Pn。金手指、瑞都红玉、甜蜜蓝宝石的耐弱光能力和在遮阴条件下的Pn均较高,最大Pn分别达到15.2、14.4、12.6μmol·m^(-2)·s^(-1)。不同品种的Pm与日Pn最大值高低顺序基本一致,甜蜜蓝宝石、金手指的日Pn最大值较高,分别达到15.9、15.7μmol·m^(-2)·s^(-1)。巨玫瑰、甜蜜蓝宝石、浪漫红颜的LSP较高,均大于1300μmol·m^(-2)·s^(-1)。在大棚高温条件下,金手指、蜜光、瑞都红玉的Pn较高,巨玫瑰、阳光玫瑰、夏黑、甜蜜蓝宝石、浪漫红颜的Pn显著降低。【结论】金手指、瑞都红玉具有较强的耐弱光能力和抗高温能力,适合各种模式设施栽培;甜蜜蓝宝石具有较强的耐弱光能力,但抗高温能力较差,适合促早和延迟栽培;蜜光具有中等的耐弱光能力和较强的抗高温能力,适合避雨栽培;夏黑、阳光玫瑰具有中等的耐弱光能力和较差的抗高温能力,适合促早栽培;浪漫红颜、巨玫瑰的耐弱光和抗高温能力均较差,不适合设施栽培。
