南京农业大学农学院《Plant Cell》发表宋庆鑫教授团队“Asymmetric variation of DNA methylation during domestication and de-domestication of rice”（图）
宋庆鑫 水稻栽培 基因
2023/10/28
水稻是全球最为重要的粮食作物之一，在其漫长的驯化过程中形成了形态各异的水稻栽培亚型，包括粳稻、籼稻、Aro和Aus等。在水稻栽培种植历史过程中，有些水稻逐渐恢复部分野生稻表型特征，最终演化成严重威胁全球水稻产量的杂草稻，这种现象称之为“去驯化”。通过基因组进化研究发现，大量驯化位点的变异在去驯化过程中并不能得到恢复，这就暗示着可能存在别的遗传机制来调控杂草稻在去驯化过程中恢复野生稻表型。DNA甲基...

棉花 DMP 基因家族 系统分析
2024/4/16
对16种植物的174个DMP基因的系统发育进行分析，这可分为5个亚家族(I-V)；4个棉种包括58个DMP基因，大部分棉花DMP主要在生殖器官(萼片、花瓣、雌蕊和花药)和次生细胞壁期纤维中表达；基因互作网络表明：DMP作为一种内膜系统参与植物衰老过程和花的生殖发育。本研究对棉花DMP基因家族进行了系统分析，探究了候选基因的潜在功能。

真空预冷处理对青花菜贮藏期间生理活性的影响（Effect of Vacuum Pre-cooling on Physiological Activities of Broccoli during Storage）
青花菜 真空预冷 生理活性
2009/11/3
将真空预冷技术应用于冷藏保鲜青花菜的预处理中，研究了真空预冷处理对青花菜在5℃贮藏期间生理活性的影响。结果表明：与不进行预冷处理样品相比，真空预冷抑制了青花菜的呼吸速率、乙烯释放量，其中失重率减少了2.18%；改善了青花菜的感官品质，减少了叶绿素和维生素C的损失，并通过调节抗氧化酶的活性起到了延缓青花菜衰老的作用。
生物多孔材料干燥过程中组织非稳态收缩（Transient Shrinkage of Tissue of Bio-porous Material during Dehydration）
豌豆 生物多孔材料 非稳态收缩
2009/9/25
根据颗粒体积收缩和平均湿度的变化规律，提出了生物多孔材料干燥组织非稳态收缩的递推模型。利用该模型对40℃热空气干燥下的豌豆各单元层边界半径变化、收缩位移及各层组织的收缩量变化进行了计算。计算结果表明：豌豆在干燥过程中随着湿分的对外迁移、湿度降低，豌豆组织收缩并不是由外向内同步收缩，而是先失去水分的外部先收缩，没有失水的部位不收缩。同时，与内部相比，外部失水较多，收缩幅度也较大。
