自交与异交象牙参属植物的蜜腺结构及其生物学意义

蜜腺是有花植物与传粉昆虫构建互惠关系的关键花部结构,解析不同繁殖特性物种间蜜腺结构的差异可为理解有花植物繁殖特性的演化提供理论依据。以传粉系统高度特化、异交实现有性生殖的早花象牙参（Roscoea cautleoides）和缺乏有效传粉者、主动自交实现有性生殖的无柄象牙参（R. schneideriana）为材料,通过野外测量2个物种蜜腺特性、超景深显微镜观察和石蜡切片染色,探究早花象牙参与无柄象牙参在蜜腺分布位置、外部形态及内部结构的异同。结果表明：2个物种均具有结构蜜腺,从外部形态来看,早花象牙参蜜腺体积较大、分泌糖浓度较高的花蜜,而无柄象牙参蜜腺体积较小、无花蜜分泌;从内部结构来看,早花象牙参蜜腺结构特化、各个组成部分有明显的区分,而无柄象牙参蜜腺出现一定程度的退化。该研究结果为揭示早花象牙参与无柄象牙参在花部特征、传粉机制及繁育系统的差异以及无柄象牙参蜜腺无花蜜分泌的可能机理提供了重要的形态学依据,也为深入地探讨植物与传粉动物间的协同进化关系以及理解蜜腺多样性的起源与维持机制奠定了科学基础。

HAT-RAPD技术在姜科象牙参属植物自然杂交个体鉴定中的应用

自然杂交在植物中广泛存在,对植物进化起着重要的作用.研究自然杂交现象,除了传粉、形态等传统手段,还需要分子水平的证据.本研究利用HAT-RAPD技术,对姜科象牙参属植物的自然杂交现象进行分析,运用主坐标分析和杂交指数分析对疑似杂交个体进行鉴定,探讨HAT-RAPD技术在分析和鉴定杂交个体方面的可行性.结果显示,HAT-RAPD方法比传统RAPD扩增的条带更稳定、清楚、容易统计,同时主坐标分析和杂交指数分析的结果表明,形态介于大花象牙参(Roscoea humeana)和早花象牙参(R.cautleoides)的个体是两者的杂交后代,且与大花象牙参的亲缘关系更近.以上的结果表明HAT-RAPD技术可以用于自然杂交的分析,并且由于其简单、易操作等特点,将成为一种非常适合分析和鉴定杂交个体的分子手段.

Phylogeny and taxonomy of Halimeda incrassata,including descriptions of H. kanaloana and H. heteromorpha spp. nov. (Bryopsidales,Chlorophyta)

The tropical green algal genus Halimeda is one of the best studied examples of pseudo-cryptic diversity within the algae. Previous molecular and morphometric studies revealed that within Halimeda section Rhipsalis, Halimeda incrassata included three pseudo-cryptic entities and that the morphological boundaries between H. incrassata and Halimeda melanesica were ill-defined. In this paper, the taxonomy of H. incrassata is revised: two pseudo-cryptic entities are described as new species, Halimeda kanaloana and Halimed heteromorpha, while H. incrassata is redefined to encompass a single, monophyletic entity. Similarities and differences between the three species and H. melanesica are discussed. Monophyly of H. heteromorpha, which was questioned in a former study, is reinvestigated using sets of 32 ITS1–ITS2 and 21 plastid rps3 sequences and various alignment and inference methods. The phylogenetic relationships within Halimeda section Rhipsalis are inferred from nuclear 18S–ITS1–5.8S–ITS2 and concatenated plastid sequences (tufA & rpl5–rps8–infA) and interpreted in a biogeographic context.     

Structural basis of nucleosome dynamics modulation by histone variants H2A.B and H2A.Z.2.2

Nucleosomes are dynamic entities with wide‐ranging compositional variations. Human histone variants H2A.B and H2A.Z.2.2 play critical roles in multiple biological processes by forming unstable nucleosomes and open chromatin structures, but how H2A.B and H2A.Z.2.2 confer these dynamic features to nucleosomes remains unclear. Here, we report cryo‐EM structures of nucleosome core particles containing human H2A.B (H2A.B‐NCP) at atomic resolution, identifying large‐scale structural rearrangements in the histone octamer in H2A.B‐NCP. H2A.B‐NCP compacts approximately 103 bp of DNA wrapping around the core histones in approximately 1.2 left‐handed superhelical turns, in sharp contrast to canonical nucleosome encompassing approximately 1.7 turns of DNA. Micrococcal nuclease digestion assay reveals that nineteen H2A.B‐specific residues, including a ROF (“regulating‐octamer‐folding”) sequence of six consecutive residues, are responsible for loosening of H2A.B‐NCPs. Unlike H2A.B‐NCP, the H2A.Z.2.2‐containing nucleosome (Z.2.2‐NCP) adopts a less‐extended structure and compacts around 125 bp of DNA. Further investigation uncovers a crucial role for the H2A.Z.2.2‐specific ROF in both H2A.Z.2.2‐NCP opening and SWR1‐dependent histone replacement. Taken together, these first high‐resolution structure of unstable nucleosomes induced by histone H2A variants elucidate specific functions of H2A.B and H2A.Z.2.2 in enhancing chromatin dynamics.
