[Ben] They are in the bean family, they look like magic beans.

它们属于豆科植物，它们看起来像魔豆。

Among the well known legumes, soybean is the richest in protein and also the cheapest sustenance.

在已知的豆科物中，大豆是蛋白质最丰富也是最廉价的物来源。

Well, that's very kind of you...but I still don't have time to explain what a legume is!

嗯，你真好......但是我还是没有时间解释豆科植物是什么！

We don't eat the leaves of the flower of the bean plant.

我们不吃豆科植物的叶子和花。

The beans which we eat are the seeds of the bean plant.

我们用的豆子是豆科植物的种子。

180. The lean man leans on the clean bean plant to read a leaf leaflet.

瘦人斜靠在干净的豆科植物上读叶传单。

The lean man leans on the clean bean plant to read a leaf leaflet.

瘦人斜靠在干净的豆科植物上读叶传单。

Now the fungal symbiosis is not limited to legumes like that soybean.

现在，这种真菌共生现象并不仅限于像大豆这样的豆科植物。

Now, unfortunately, the nitrogen-fixing symbiosis is limited to legumes like that soybean and their relatives.

遗憾的是，目前固氮共生仅限于大豆及其近缘的豆科植物。

So we are working on transferring that nitrogen-fixing symbiosis from legumes to our cereal crops.

此，我们正致力于将这种固氮共生关系从豆科植物转移到我们的谷类作物上。

Like other seeds, beans come from the flowers on a plant — in this case, bean plants.

像其他种子一样， 豆类来自植物的花朵——在这种情况下，是豆科植物。

Because almost all plants, apart from legumes, can't convert this lovely nitrogen from the atmosphere into the ammonia that it can actually use.

乎所有的植物，除了豆科植物，不能将大气中这些可爱的氮转化氨。

I said C) a legume, because that was the only one I didn't know and it can't be as simple as being a nut!

我说的是 C. 豆科植物，这是我唯一不知道的，而且不可能是坚果那么简单！

What we now understand is that when legumes evolve this capability to engage with nitrogen-fixing bacteria, they didn't invent anything new.

我们现在明白的是， 当豆科植物进化出与固氮细菌互动的能力时，它们并没有创造出什么新东西。

That L-DOPA plays a role (albeit a different one) in communication in species as diverse as human beings and bean plants is intriguing.

左旋多巴在人类和豆科植物等多种物种的交流中发挥着重要作用（尽管是不同的），这很有趣。

You can see that they like put more desert ecology, had a focus on cactuses on the Mesquite tree on re on redesigning the real.

你可以看到他们喜欢把更多的沙漠生态放在重新设计真正的豆科灌木树上的仙人掌上。

Now this work is not yet published, but using this knowledge and getting the networking of those pre-existing genetic components right, we have now been able to engineer nodules in non-legumes.

目前这项工作尚未发表， 但借助这一知识并正确构建这些预存遗传组件的网络，我们现已成功在非豆科植物中培育出了根瘤。

Vast flats of green grass, dull-hued spaces of mesquite and cactus, little groups of frame houses, woods of light and tender trees, all were sweeping into the east, sweeping over the horizon, a precipice.

大的绿草地， 暗淡的豆科灌木和仙人掌，一小群木屋， 轻柔的树林，都向东席卷， 扫过地平线，悬崖峭壁。

And that gets into a whole other thing too, how you're using wood, green wood, dry wood, post oak, hickory, mesquite, pecan, any of these different kinds of woods they all taste different, they all cook different.

这也涉及到另一件事，你如何使用木材，绿色木材，干木，星毛栎，山核桃，豆科植物，美洲山核桃，任何这些不同种类的木材，它们味道都不同，烹饪方式也不同。

They are grown in more than 50 countries, particularly in Asia and Africa, and contribute 11.5m tonnes of protein-rich pulses to the world's food supply, making them the third most productive leguminous food crop, after beans and peas.

在50多个国（在亚洲和非洲特别多）都有种植，世界粮供应贡献了1150万吨富含蛋白质的豆类，使其成仅次于黄豆和豌豆的第三大豆科粮作物。
