植物 维管结构 综合表征
2021/1/13
一直以来，对于叶片中的维管细胞，特别是韧皮部薄壁组织，人们知之甚少。近日，德美两国研究人员首次利用单细胞测序对拟南芥叶片维管细胞进行全面分析。相关论文刊登于《植物细胞》。研究人员首次成功分离了植物细胞，并创建了一个包含叶片维管系统所有调节RNA分子的图谱，从而通过分析代谢途径来确定不同细胞的作用。

植物化学 记忆影响 后代 存活机会
2020/12/3
英国华威大学研究人员揭示了，植物将“记忆”传递给后代导致生长和发育缺陷的相关机制。近日，该研究刊登于 elife。为了生存和茁壮成长，植物具有感知和记住环境变化的独特能力。这与DNA和组蛋白的化学修饰有关，这些修饰改变了DNA在细胞核内的包装方式和基因表达方式——这一过程被称为表观遗传调控。通常，这种表观遗传信息会在有性繁殖过程中被重置，以消除任何不恰当的“记忆”，确保后代的正常生长。这里，研究人...

One of the best sources of information on the evolution of terrestrial ecosystems and plant diversity over millions of years is fossil pollen. For palynologists -- the scientists who study ancient pol...
In an elegant choreography, plants take cues from their environment and channel them into forms: flowers, roots and branches. In a new paper published in Nature Communications, biologist Doris Wa...
Almost 100 years ago, there was a strange, slow-motion takeover of the Great Plains.During the Dust Bowl of the 1930s, as a heatwave and drought swept the middle of the United States, there was a dram...

Death Valley doesn't seem like the best place to ride out rising temperatures amid a changing climate. But for the desert plants that live there, it's home -- and they face the choice to adapt or die....
How do sunflowers manage to grow in the desert? Wild sunflowers display extensive variation, both between and within species. Scientists now report that variation is preserved by blocks of "supergenes...
