WRKY transcription factors are crucial regulatory components of plant responses to pathogen *** the present study,we report isolation and functional characterization of WRKY30 gene in rice. RT-PCR was used to amplify WRKY30 cDNA sequence including its largest open reading frame in length of 2022 bp,and was predicted to encode a protein of 674 amino acid residues consisting of two WRKY domains each with a zinc finger motif of CH and a nuclear localization signal,belonging to the WRKY groupⅠ.WRKY30 shared high amino acid sequence identity with those from monocots such as wheat (Hordeum vulgare),Sorghum bicolor and Brachypodium ***30 exists as a single copy in the rice genome as determined by Southern *** transcript levels of WRKY30 were relatively high in stem,leaf and grain,next were root and panicle,and the least was *** gene was rapidly induced in response to challenges with Magnaporthe grisea and Rhizoctonia solani,and also induced by exogenous salicylic acid(SA) and methyl jasmonate(MeJA),the two important defense-related hormones,and mechanical ***,Ethephon,cold,high salt and dehydration exerted no obvious effects on its *** of WRKY30 in rice enhanced resistance to rice sheath blight fungus *** and blast fungus *** enhanced resistance in the transgenic overexpression lines was associated with activated expression of a subset of SA- and JA-regulated defense-related genes and increased accumulation of JA under the challenge of the fungal pathogen.

The distribution of crystal organic fertilizer, urea and compound fertilizer-N in soil and plant system was researched with 15N-trace under tobacco pot experiment. The results showed that the leaf yield of tobacco used crystal organic fertilizer was 23.1% and 14.6% higher than that of urea and compound fertilizer treatments respectively. Compound fertilizer also resulted in higher yield of 8.5 % comparing with the urea treatment. Nitrogen content of the plant from the crystal organic fertilizer treatment was 138. 6% and 145.7% as high as that of the compound fertilizer and urea treatments respectively. The absorbed N from the organic fertilizer was 25.1% and 27.9% more than that from the compound fertilizer and urea respectively. However, the absorbed N from the soil with the organic fertilizer was 47.4% and 58.3% more than that with compound fertilizer and urea respectively. The N use efficiency of the organic fertilizer was 9.4% and 10.1% higher than that of the compound fertilizer and urea. It indicated that the crystal organic fertilizer not only had high N use efficiency, but also stimulated tobacco taking up more N from soil.

This review addresses the growing disparity between the current state of fertilizer production in china and the evolving demands of green agriculture in the 21st century. It explores major advances in fertilizers, proposes the concept of green intelligent fertilizers and develops new strategies aligned with the principles of green development in fertilizer industry and *** intelligent fertilizers may be designed to maximize the synergistic effects among plants, soils, microorganisms, nutrient sources and the environment. This concept emphasizes the integration of industry and agriculture toward green development for entire industry chain, using an interdisciplinary approach to drive the green transformation of fertilizer industry, and promote green and sustainable development of agriculture. By bridging the gap between the current state of fertilizer industry and a growing need for environmentally responsible agricultural practices, this review highlights a path toward harmonizing fertilizer production with the imperatives of green agriculture.

为了定量分析北京山区农业气候资源,利用山区1 km2小网格的气候资料,应用农业气候适宜度理论、模糊数学和因子分析等方法,通过5项农业气候指标与山区栽培植物生长发育条件之间隶属函数的建立及其权重的确定,分别计算山区各网格点的农业气候资源指数、效能指数和利用系数,并在GIS的支持下建立了它们的栅格图。结果表明:北京山区以平谷、密云、怀柔南部等东北部地区的农业气候资源系统较为优良,无论是气候资源总量还是其匹配状况以及利用率都是本地区最高的;与之相反,西北部和海拔较高的山区,不仅农业气候资源总量贫乏,而且光、热、水资源的匹配程度较差,导致农作物对资源的利用率较低;此外,房山东南部和昌平南部等地区气候资源总量较为丰富,但受水资源的限制,光、热、水资源的匹配程度较差,致使当地气候资源利用率较低。

Hippeastrum, a highly diverse genus in the Amaryllidaceae family, is a valuable ornamental bulbous flowering plant. Somatic embryogenesis(SE) is an efficient method for mass production of Hippeastrum plantlets. Previous studies have been devoted to the in vitro propagation of Hippeastrum, but the SE and its regulatory networks are rarely reported. In this study, we established a direct SE method of Hippeastrum Bangkok Rose' using leaf bases as explants. MS supplemented with 1.00 mg·L^(-1)NAA +1.00 mg·L^(-1)KT + 0.25 mg·L^(-1)TDZ was the optimal medium for SE. Histological observations showed that the bipolar somatic embryo originated from the epidermal cell layer and underwent initiation,globular, scutellar and coleoptile stages. During SE, endogenous hormones of IAA, CTK, ABA, and SA were highly accumulated. Transcriptomic analysis revealed the genes encoding auxin biosynthesis/metabolic enzymes and efflux carriers were induced, while the auxin receptor of TIR1 and ARF transcriptional repressor of Aux/IAA were down-regulated and up-regulated, respectively, leading to suppression of auxin signaling. In contrast, cytokine signaling was promoted at the early stage of SE, as biosynthesis, transport, and signaling components were *** stress-related genes were up-regulated at the early or late stages of SE. Chromatin remodeling could also be dynamically regulated via distinct expression enzymes that control histone methylation and acetylation during SE. Moreover, key SE regulators, including WOXs and SERKs were highly expressed along with SE. Overall, the present study provides insights into the SE regulatory mechanisms of the Hippeastrum.
