【摘要】

：

Q:我国的麻雀是从俄罗斯引进的吗?rnA:不是.20世纪50年代,中国把麻雀列为“四害”之一.后来,当麻雀在自然中的重要作用被重新认识后,我国开展了保护工作.只要给麻雀足够的时间和生存空间,它们数量的恢复是很快的,原因之一是麻雀的繁殖能力较强.麻雀每年能孵化三窝蛋,每窝顺利出巢的雏鸟能有约3～6只.至于从国外引进大量麻雀,技术上不可行,也没有相关记录,只是谣言罢了.再说麻雀自己有翅膀,想过来也不用咱们“引进”呀!

O2-ZmGRAS11 coordinates cell expansion and endosperm filling

Maize(Zea mays),a major crop for food and feed,is grown world-wide with a high annual yield.The grain size and weight of maize are mainly determined by starch and storage proteins that are actively synthesized during endosperm filling.During early endo-sp

Moonlighting PPKL1 reveals a role of cytokinin in regulating rice grain size

Rice is the staple food of more than half of the world\'s population,and major efforts are being made to improve rice yield.Rice yield is mainly determined by three components:number of panicles per plant,number of grains per panicle,and grain weight,wh

Nitric oxide regulation of plant metabolism

Nitric oxide(NO)has emerged as an important signal molecule in plants,having myriad roles in plant devel-opment.In addition,NO also orchestrates both biotic and abiotic stress responses,during which intensive cellular metabolic reprogramming occurs.Integr
