Drought decreases carbon flux but not transport speed of newly fixed carbon from leaves to sinks in a giant bamboo forest

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1746-1759, July 2025.
In forests dominated by large clonal plants, such as giant moso bamboo, drought can alter the allocation of newly assimilated C within the tissues of source ramet but may not affect its allocation among interconnected ramets or within plant–soil systems.

General‐purpose genotypes and evolution of higher plasticity in clonality underlie knotweed invasion

open access: yesNew Phytologist, Volume 246, Issue 2, Page 758-768, April 2025.
Summary Many widespread invasive plant species express high phenotypic variation across novel environments, providing a unique opportunity to examine ecological and evolutionary dynamics under global change. However, studies often lack information about the origin of introduced populations, limiting our understanding of post‐introduction evolution.

A multicentric intermediate‐size B‐cell lymphoma with epitheliotropism in a Freiberger mare

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 573-577, October 2024.
This report describes a multicentric intermediate‐size B‐cell lymphoma with epitheliotropism in a Freiberger mare affecting multiple mucous membranes, skin and internal organs. The clonal neoplastic B‐cell population was accompanied by numerous reactive polyclonal small T cells. Differential diagnoses for these unusual findings are discussed.

银鲫果糖-1,6-二磷酸酶的分子克隆与表达分析 [PDF]

open access: yes, 2010
果糖-1,6-二磷酸酶(EC 3.1.3.11)是糖异生中的关键限速酶之一,在糖代谢中起重要作用。哺乳动物存在肝脏型和肌肉型两种果糖-1,6-二磷酸酶同工酶,分别由Fbp1和Fbp2编码。银鲫作为我国重要的经济养殖鱼类,尚无果糖-1,6-二磷酸酶基因的有关资料,其组织分布特征和胚胎发育模式亦不清楚。本研究采用RACE方法从银鲫原肠胚SMART cDNA文库中扩增了果糖-1,6-二磷酸酶基因的全长cDNA,其长度为1170 bp,编码337个氨基酸残基,多重序列比对和系统发育分析表明该基因为肝脏型果糖 ...

赤点石斑鱼促甲状腺激素TSHβ启动子的克隆及其在斑马鱼胚胎原始性腺和垂体中定位表达 [PDF]

open access: yes, 2010
促甲状腺激素(Thyroid-stimulating hormone,TSH)具有调节生长,发育,代谢和生殖的功能,但是在低等脊椎动物中的功能研究较少。斜带石斑鱼(Epinephelus coioides)促甲状腺激素TSHβ除在垂体中表达外还在性腺中表达,进一步发现TSHβ也在赤点石斑鱼(Epinephelus akaara)性腺中表达。且在人工诱导的赤点石斑鱼中,随着雄性化的转变,TSHβ转录水平升高。为研究石斑鱼TSHβ特殊表达方式的调控机制,采用基因组步移技术扩增获得赤点石斑鱼TSHβ5 ...

再生障碍性贫血儿童TCR Vβ亚家族T细胞克隆性增殖及其与HLA—DRB1*15的关系

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2006
【目的】探讨再生障碍性贫血(再障)儿童TCR Vβ24个亚家族T细胞克隆性及其与HLA—DRB1*15的关系。【方法】再障儿童17例(SAA14例,MAA3例),采用RT—PCR和基因扫描分析外周血或骨髓TCR Vβ24个亚家族基因的表达和克隆性,SSP—PCR检测HLA—DR。【结果】再障儿童外周血T细胞仅表达4—22个Vβ亚家族,而正常儿童外周血T细胞几乎表达所有Vβ亚家族。12例(包括初诊SAA4例,CR4例,复发1例和MAA3例)再障儿童存在不同程度T细胞克隆性增殖,但个体间差异较大 ...
