Two thirds of the crops planted last season failed, while Ngamiland, a rich beef producing region, has recorded nearly 40,000 cattle deaths.

上一季种植的作物三分之二歉收，而盛产牛肉的Ngamiland地区已经近4万头牛死亡，已创纪录。

There are good reasons why crop plants do not use dryness defenses already.

作物植物尚未使用干燥防御系统是有充分理由的。

With climate change causing more frequent heat waves and droughts, crop plants may become stressed, reducing yields and threatening food security.

随着气候变化导致更频繁的热浪和干旱， 农作物可能会受到压力，从而降低产量并威胁粮食安全。

And you want to transfer that gene into a crop plant because you want to protect the crop against pest damage.

你想将该基因转移到农作物中， 因为你想保护农作物免受害虫侵害。

And I'll tell you why we're picking crop plants to do the work for us when I get to that part of my talk.

当我讲到那部分时，我会告诉你为什么我们要采摘农作物来为我们做这项工作。

Let's say you already managed to take the gene out of the wild plant and now you were trying to put it into the crop plant cells.

假设您已经设法从野生植物中提取基因， 现在您正试图将其放入农作物细胞中。

The work was done in a model system, using a mustard plant called Arabidopsis, but Wigge says the phytochrome genes necessary for temperature sensing are found in crop plants as well.

这项工作是在一个模型系统中完成的，使用了一种叫做拟南芥的芥菜植物，但 Wigge 说， 在农作物中也发现了温度感应所必需的光敏色素基因。

'Recent advances in plant genetics now mean that scientists are able to rapidly identify the genes controlling these processes in crop plants, and even alter their activity using precise molecular" scalpels" , ' adds Wigge.

“植物遗传学的最新进展现在意味着科学家们能够快速识别控制农作物中这些过程的基因，甚至可以使用精确的分子“手术刀” 改变它们的活性， ”Wigge 补充道。
