ROS-Mediated ABA Signaling

In plants, reactive oxygen species (ROS) are short-lived molecules produced through various cellular mechanisms in response to biotic and abiotic stimuli. ROS function as second messengers for hormone signaling, development, oxygen deprivation, programmed cell death, and plant–pathogen interactions. Recent research on ROS-mediated responses has produced stimulating findings such as the specific sources of ROS production, molecular elements that work in ROS-mediated signaling and homeostasis, and a ROS-regulated gene network (Neill et al., Curr Opin Plant Biol 5:388–395, 2002a; Apel and Hirt, Annu Rev Plant Biol 55:373–399, 2004; Mittler et al., Trends Plant Sci 9:490–498, 2004; Mori and Schroeder, Plant Physiol 135:702–708, 2004; Kwak et al., Plant Physiol 141:323–329, 2006; Torres et al., Plant Physiol 141:373–378, 2006; Miller et al., Physiol Plant 133:481–489, 2008). In this review, we highlight new discoveries in ROS-mediated abscisic acid (ABA) signaling. Drs. Daeshik Cho and June M. Kwak are the corresponding authors for this paper.

Quaternary structure of rice nonsymbiotic hemoglobin

Plant nonsymbiotic hemoglobins are hexacoordinate heme proteins found in all plants. Although expression is linked with hypoxic environmental conditions (Taylor, E. R., Nie, X. Z., Alexander, W. M., and Hill, R. D. (1994) Plant Mol. Biol. 24, 853-862), no discrete physiological function has yet been attributed to this family of proteins. The crystal structure of a nonsymbiotic hemoglobin from rice has recently been determined. The crystalline protein is homodimeric and hexacoordinate with two histidine side chains coordinating the heme iron atom. Despite the fact that the amino acids responsible for the subunit interface are relatively conserved among the nonsymbiotic hemoglobins, previous work suggests that this group of proteins might display variability in quaternary structure (Duff, S. M. G., Wittenberg, J. B., and Hill, R. D. (1997) J. Biol. Chem. 272, 16746-16752; Arredondo-Peter, R., Hargrove, M. S., Sarath, G., Moran, J. F., Lohrman, J., Olson, J. S., and Klucas, R. V. (1997) Plant Physiol. 115, 1259-1266). Analytical ultracentrifugation and size exclusion high pressure liquid chromatography were used to investigate the quaternary structure of rice nonsymbiotic hemoglobin at various states of ligation and oxidation. Additionally, site-directed mutagenesis was used to test the role of several interface amino acids in dimer formation and ligand binding. Results were analyzed in light of possible physiological functions and indicate that the plant nonsymbiotic hemoglobins are not oxygen transport proteins but more closely resemble known oxygen sensors.

蛋白质类生物制品几种不合格冻干外观及解决方案

冻干即真空冷冻干燥,是利用升华的原理使物料脱水的一种干燥技术,其广泛用于生物制品,特别是蛋白质类生物制品的生产,以保护生物制品生物活性成分。外观是冻干制品的重要质量属性之一,合格的冻干制品外观应是疏松多孔、色泽均匀、质地细腻的固体。在大规模生产中,由于冻干参数复杂、设备操作的灵活性等因素,冻干制品的饼块有时会出现收缩、裂化、塌陷、雾化、回熔、喷瓶、结膜等不合格外观,从而造成极大的经济损失。现就近年来在蛋白质类生物制品冻干过程中易发生的几种不合格外观及解决方案作一概述。

肺炎链球菌C多糖含量检测方法的建立

目的使用肺炎链球菌C多糖单克隆抗体(单抗),建立检测荚膜多糖中残留的C多糖含量的方法。方法选择BALB/c雌性小鼠,采用体内诱生单抗腹水,放大生产肺炎链球菌C多糖单抗;使用间接ELISA、抑制性ELISA对其进行特异性鉴定;用特异性和亲和力高的单抗尝试建立肺炎链球菌荚膜多糖中C多糖含量检测的速率比浊法,并对该方法的线性、精密度、特异性进行验证。结果所制4株单抗的抗体类别均为IgM,识别的抗原表位互不相同,亲和力也不同。间接ELISA、抑制性ELISA结果均显示,所获得的单抗能够作用于肺炎链球菌C多糖上的磷酸胆碱位点,具有很好的特异性。选择单抗E8建立速率比浊检测方法的线性、精密度和特异性均良好,检测结果表明肺炎链球菌23个血清型荚膜多糖中C多糖含量不同。结论利用单抗建立了检测肺炎链球菌荚膜多糖中残留的C多糖的含量的速率比浊法。
