在自然界中,种子在土壤中萌发后,将迅速穿破土层获取光照进行光合作用等生理活动。此时,幼苗下胚轴或茎迅速伸长,双子叶植物的子叶闭合并形成弯钩,以克服出土的压力。幼苗出土见光后,下胚轴或茎的伸长受到抑制、弯钩打开、子叶张开、叶绿体发育完善并合成叶绿素,进行光合作用。土壤下的暗形态建成和见光后的光形态建成是大多数种子植物所必须经历的生长发育过程。
次生代谢产物异黄酮是一类主要在豆科植物中合成的多酚类物质。异黄酮不仅利于豆科植物应答生物和非生物胁迫、诱导根瘤形成等,而且对人体具有重要的保健和药用价值,比如预防和治疗癌症、心脑血管疾病和骨质疏松等。大豆是工业化生产异黄酮的重要来源,主要含有12种异黄酮物质及其衍生物。根据其化学结构的差异,可将其分为游离型苷元(aglycone)和结合型糖苷(glycoside)两大类,其中结合型糖苷占异黄酮总量...

Sign language gloves, intended to help people with visual disabilities, turn fingerspelling into text on a smartphone or computer. But fingerspelling makes up only a small part of the American Sign La...
Lysine is the main limiting essential amino acid (EAA) in the rice seeds, which is a major energy and nutrition source for humans and livestock. In higher plants, the rate-limiting steps in lysine bio...
Examinations are typically used in higher education to objectively assess student learning, and they are also used as a frequent assessment tool in the Doctor of Pharmacy curriculum. This paper descri...
After 26 years, the world’s longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundan...
Does blinking function as a type of feedback in conversation? To address this question, we built a corpus of Dutch conversations, identified short and long addressee blinks during extended turns, and ...
