Histone H3 is one of the four histones, along with H2A, H2B, and H4, which form the eukaryotic nucleosome octamer core. In this study, a new gene RH3.2A encoding an H3.2-type histone H3 protein from rice (Oryza sativa L.) was reported. RH3.2A was cloned through RT-PCR from salt-treated rice seedlings.

本研究从盐胁迫处理的水稻幼苗组织中分离了一个新的水稻组蛋白H3基因RH3.2A，编码具有136个氨基酸残基的多肽，与多种植物的组蛋白H3蛋白具有高度的氨基酸一致性。

Microsatellites in various components in Oryza sativa SSP. Japanica were computed and censused. The result showed: Microsatellites distributed in both coding regions and non-coding regions of genes and other regions in rice genome. The only quantitative relationship of microsatellites among regions could be confirmed. In quantitative, microsatellite content in non-coding region is higher than in coding region, but the nature of tri-nucleotide microsatellite excepts. That microsatellites in rice EST sequences are plentiful was found similar to the research before.

对水稻基因组中各成分的微卫星进行统计分析，结果表明：微卫星在基因的编码区和非编码区都有分布，主要是数量上的差异；在数量关系上，非编码区的微卫星含量大大高于编码区，但是三核苷酸微卫星相反；在水稻EST中微卫星含量非常丰富；在微卫星motif长度使用上，二核苷酸微卫星的含量最高，且以at/ta微卫星占大多数；比较籼稻和粳稻基因组上的微卫星，发现它们在含量、组成和motif使用频率上都非常相似。

A compartmented rhizo-bag culture system was used to study the effects of exogenous phosphorus on arsenic fractions in the rhizosphere and their bioavailability to rice (Oryza sativa L.) and wheat Triticum aestivum L.

Medicago sativa in the initial flowering stage was harvested and wilted for 0,6,18,or 28 h and was ensiled with different water contents(80.3%,71.2%,62.5% and 40.3% respectively) and additive mixtures.

在刚收获及收获后经6，18和28 h晾晒的初花期苜蓿青贮料中，加入不同糖分、乳酸菌和纤维素酶浓度的乳酸菌复合添加剂进行青贮，并按正交原理设计试验。

In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

针对苜蓿雄性不育系杂交制种产量低的问题，采用杂交法对苜蓿雄性不育系进行改良，以原苜蓿雄性不育系为轮回亲本与雄性可育优良苜蓿品种杂交，分析苜蓿雄性不育系及其杂交后代种子产量的影响因素，从细胞形态学方面观察和分析杂交后代及原不育系在雌性生殖器官上的变异特点，从酶蛋白水平对杂交后代及原不育系的遗传差异进行分析，初步研究结果如下： 1、苜蓿雄性不育系与草原一号苜蓿的杂交后代不育株BC1-2，以及苜蓿雄性不育系与X′(苜蓿雄性不育系与新疆大叶苜蓿的杂种F1代)的杂交后代不育株BC1-19、BC1-21、BC1-22、BC1-23的天然杂交结荚率和人工杂交制种的结荚率和百粒重均高于原苜蓿雄性不育系。

Sativa× Shennong 133 was done. Traits of both purpled awn and purpled stigma were appearance in F1 and purpled plant was appearance in F5, respectively.
