Overexpression of the yeast HAL2 gene increases salt tolerance of yeast and plant. Rice HAL2-like (RHL) gene was introduced into a japonica rice cultivar HJ19 with agrobacterium tumefaciens-mediated transformation. Transgenic plants in R0 generation were selected on the principle of GUS-positive, RHL gene PCR-positive and normal growth. Hygromycin-resistant plants of some transgenic lines in R1 generation increased salt tolerance during the seedling and booting stage, being less damaged in the cy-tomembrane and stronger in leaf tissue viability under salt stress during booting period. Southern analysis of transgenic lines tolerant to salt in R1 generation showed that the RHL gene expression cassette had been successfully integrated into rice genome. Moreover, gene engineering breeding methodology and really salt-tolerant rice cultivar were discussed.

Let DerA be the Lie algebra of derivations of the d-torus A = C[t1± 1, . . . , td±1]. By applying Shen-Larsson’s functors we get a class of indecomposable DerA-modules from finite-dimensional indecomposable gld-modules. We also give a complete description of the submodules of these indecomposable DerA-modules. Our results generalize those obtained by Rao.

Sexual incompatibility between common wheat and Italian ryegrass was an obstacle for transferring useful traits from italian ryegrass to wheat. In order to use those desirable genetic resources to improve wheat and to create new cytoplasmic germplasm, the protoplasts of wheat and Italian ryegrass were successfully electrofused and the somatic hybrid plants were regenerated. Examination with 6 restriction enzymes, 13 probes including 9 mtDNA probes (H454, Pst24, B30, Pro I, 490, B342, pHJ2-7-l, B376, 7), 3 cpDNA probes (pHvc p1, pHvc p5 and pHvc p8) and onenuclear DNA probe-pTA71 (rDNA) in total 73 enzyme/probe combinations revealed rich polymorphism between the fusion partners. RFLP analysis indicated that approximately 93.4% of the regenerated plants were true somatic hybrids. AFLP analysis implied that the somatic hybrids were highly asymmetric. The RFLP analysis using mt- and cpDNA specific probes also demonstrated the non-coexistence of mitochondria and chloroplasts from the fusion partners in the

应用混合品种控制小麦条锈病在国内外日益受到重视,通过采集田间不同品种混合小麦条锈病各级病情梯度的高光谱遥感数据,将光谱数据与条锈病病情数据进行相关性分析,利用4个光谱参数构建其与病情指数的回归模型。结果表明,不同小麦品种组合在不同的病情指数情况下,其冠层光谱信息都表现了一致的变化规律;冠层反射率在可见光区与病情指数为正相关,而在近红外区则达到了显著的负相关;利用690与850nm处的反射率、SDr、NDVI以及RVI与病情指数构建的回归模型拟合效果较好。研究表明利用高光谱反演条锈病病情指数是可行的,并且小麦不同品种对反演效果影响不大。

A now sesquiterpenoid named as celastrine was isolated from the seed oil of Celastrus flagellaris Rupr. Its structure was determined as 1 alpha ,6 beta ,8 alpha ,13-tetraacetoxy-9 alpha -benzoyloxy-beta -dihydroagarofuran by UV, IR, MS and NMR(H-1 NMR, C-13 NMR, H-1-H-1 COSY, H-1-C-13 COSY, NOESY and HMBC) spectra.

Dear Editor,Genome editing technologies enable precise modifications of DNA sequences in vivo and offer great promise for crop improvement. CRISPR/Cas9 （Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated Cas9） has revolution- ized genome editing because of its simplicity and versatility （Cong et al., 2013）.

The effects of ultradry seed storage on the fluidity of plasma membrane have been investigated using the DPH fluorescent probe (1,6-diphenyi-1, 3, 5,-hexatriene). The results demonstrated that the micro-viscosity of plasma membrane of ultradried seeds has no significant changes compared with the seeds which were stored under -20℃ condition. However, there is a little adverse effect on the seeds with extreme dehydration. The results were consistent with higher vigor level of ultradried seed. It indicated that ultradry seed storage could maintain the physiological function of seed, protect the integrity of the membrane and improve the storability of seed. Furthermore, the results also revealed that sugar has the effect on protecting membrane structure and preserving the fluidity of the plasma membrane under seed dehydration. In the meantime, some mechanism about ultradry seed storage and the tolerance of dehydration of seed have been discussed.

Quantitative trait locus (QTLs) mapping for rapid visco analyser (RVA) profile parameters has been carried out by using a double haploid (DH) population derived from a cross between indica variety Zhai-Ye-Qing 8 and j’aponica variety Jing-Xi 17 and its genetic linkage map. The results indicate that the segregation of the RVA profiles is continually distributed a-mong the DH lines, and some DH lines show transgressive segregation for all the parameters.
