Microspore embryogenesis is the developmental plasticity of juvenile male gametophytes to switch from pollen to embryo development upon exposure to in vitro stress. It is a common method for obtaining haploid and doubled haploid plants in breeding programs for development of superior varieties via haploid-diploidization which allows fast development of homozygous lines from heterozygous parents. In cassava, obtaining haploidization through traditional methods of successive selfing is difficult because of cassava’s long reproductive cycle, high heterozygosity, and inbreeding depression. As a first step towards microspore embryogenesis, callus induction following heat treatment has not been investigated in cassava. We used two elite Ugandan cassava varieties, hereafter called “genotypes”, NASE3 and NASE14, for the study of callus induction. Heat stress of 40°C for 0, 6, 12, 18 and 24hrs and Murashige and Skoog medium supplemented with 2-9% sucrose, and 2,4-dichlorophenoxy acetic acid were used. Heating anthers of NASE3 at 40°C for 6 hrs resulted in a significantly higher percentage of callus induction on MS medium supplemented with 2% sucrose. Callus emerged from inside of the anthers with production influenced by genotype, sucrose concentration, anther density and duration in culture (P≤0.001). Limited in vitro callus differentiation was observed on auxin-and cytokinin-supplemented media. In both genotypes, embryo genic callus was obtained in liquid medium, while green callus was achieved on solid medium. This is a significant step upstream of double haploid plant production pathway in cassava: rigorous optimization of protocols downstream of callus induction are needed for regeneration of microspore-derived embryos and haploid plants.
小孢子胚发生是雄性幼配子体在体外胁迫下由花粉向胚胎发育转变的发育可塑性。通过单倍体-二倍体分化获得单倍体和双单倍体植株是培育优良品种的一种常用方法,它可以使杂合亲本快速发育为纯合子系。在木薯中,由于木薯的繁殖周期长,杂合度高,近交抑制,通过传统的自交方法获得单倍体化是困难的。作为小孢子胚胎发生的第一步,热处理后的愈伤组织诱导尚未在木薯中进行过研究。以2个乌干达木薯优良品种NASE3和NASE14为研究对象,对其愈伤组织诱导进行了研究。采用40℃热应激0、6、12、18和24h,添加2-9%蔗糖和2,4-二氯苯氧基乙酸的Murashige和Skoog培养基。在添加2%蔗糖的MS培养基上,将NASE3花药在40℃下加热6 h,愈伤组织诱导率显著提高。愈伤组织的产生受基因型、蔗糖浓度、花药密度和培养时间的影响(P≤0.001)。在补充生长素和细胞分裂素的培养基上,愈伤组织的体外分化有限。两种基因型均在液体培养基上获得胚源性愈伤组织,在固体培养基上获得绿色愈伤组织。这是木薯双单倍体植株产生途径上游的重要一步,小孢子胚和单倍体植株的再生需要对愈伤组织诱导下游的工艺进行严格的优化。

The ultra-weak radiation from living cells has an influence on the cell renewal in tissue association. Here, the energy of electromagnetic wave from infrared range to UV-light plays a special role. The characteristics of the physical properties of water at the interface of hydrophilic surfaces, the so-called Exclusion Zones, indicate that an energy reserve is formed in this region. There is an energy input that results in an energy output in the direction of the biological material. These two observations the ultra-weak radiation from living cells and the physics of Exclusion Zones, lead to the conclusion that this is a physically energetic process that is formulated as a hypothesis to trigger germination.

Correlation between two phytohormone Abscisic acid (ABA) and salicylic acid (SA) accumulation and transcript pattern of VvNHX1, VvABF1, VvAREB2, VvCBF4 and VvOSM1 genes involved in grapevine (Vitis vinifera L.) adaptation against 2 dS/m seawater treatment for 1,3 and 5 days exposure has been assessed in Baladi and Halawani cultivars and B41 rootstock grapevine. Data revealed that VvNHX1, VvABF1, VvAREB2 and VvCBF4 transcript patterns were closely related with activation of ABA level in Halawani cv. Whereas, VvABF1 and VvAREB2 transcript patterns were closely related with activation of ABA level in Baladi cv. While, VvNHX1, VvABF1 and VvCBF4 transcript patterns were closely related with activation of ABA level in B41 rootstock. Indeed, VvOSM1 transcript pattern was closely related with ABA level in B41 rootstock. As for SA, VvNHX1 and VvCBF4 transcript patterns were closely related with SA level in Baladi cv. Whereas, VvAREB2 and VvABF1 transcript pattern was closely related with activation of SA level in B41 rootstock. While, VvOSM1 transcript pattern was closely related with activation of SA level in Halawani cv. However, its transcript pattern was inversely related with SA level in Baladi cv. Thereby, the current investigation suggests that transcript pattern of some genes were closely related with activation of ABA or SA or the both together; indicating that these genes could implicated in phytohormones pathway mediates salt tolerance in grapevines.
以Baladi和Halawani葡萄品种和B41砧木葡萄为材料,研究了葡萄对2 dS/m海水处理1、3和5 d的适应过程中,两种植物激素脱落酸(ABA)和水杨酸(SA)积累与VvNHX1、VvABF1、VvAREB2、VvCBF4和VvOSM1基因的转录模式。数据显示,VvNHX1、VvABF1、VvAREB2和VvCBF4转录模式与Halawani cv中ABA水平的激活密切相关。而VvABF1和VvAREB2转录模式与Baladi cv中ABA水平的激活密切相关。而vnhx1、VvABF1和VvCBF4转录模式与B41砧木ABA水平的激活密切相关。在B41砧木中,VvOSM1转录模式与ABA水平密切相关。对于SA, Baladi cv中VvNHX1和VvCBF4转录模式与SA水平密切相关。而VvAREB2和VvABF1转录模式与B41砧木SA水平的激活密切相关。而VvOSM1的转录模式则与海葵中SA水平的激活密切相关。在Baladi cv中,其转录模式与SA水平呈负相关。因此,目前的研究表明,一些基因的转录模式与ABA或SA的激活密切相关,或两者同时存在;说明这些基因可能与植物激素通路有关,介导了葡萄的耐盐性。

Anemia is common nutritional disorder and it affects one third of population around the globe. Assessing nutritional status of human is an inevitable process to lead a healthy life. Females are affected significantly by anemia compare to male. According to WHO report, developing herbs-based formulation to treat anemic patients is safe and less toxic. In this study a double-blind, cross group comparative clinical trial of Nabayas Louha (NBL) a Ayurvedic haematinic preparation with G-Iron Folic Acid (IFA) was undertaken on 66 female anemic volunteers with age between 20-30 years. It was seen that NBL after being administered at a daily dose of 500 mg for 30 days significantly increased the hemoglobin content of the treated volunteers. It produced an increase in serum iron content and decreases total iron binding capacity. The ESR level was also decreased. These effects of NBL were found to be comparable with IFA. There was a marked decrease in WBC count noticed, however statistically significant increase in the lymphocytes count was seen. Furthermore, the level of toxicity related enzymes SGOT and SGPT was not altered significantly in the NBL treated group which vividly confirm that supplementation of NBL is not toxic. In conclusion, these findings recommend use of NBL as supplement in the treatment of iron deficiency anemia and WBC disorders Keywords: Anemia; Ayurvedic; Haematinic; Nabayas louha Abbreviations: World health organization (WHO); Nabayas louha (NBL); Iron folic acid (IFA); Erythrocyte sedimentation rate (ESR); White blood cell (WBC); Glutamic-pyruvic transaminase (GPT); serum glutamic-oxaloacetic transaminase (SGOT); Serum glutamic pyruvic transaminase (SGPT); Total iron binding capacity (TIBC); Iron deficiency anemia (IDA)
贫血是一种常见的营养失调,影响着全球三分之一的人口。评估人的营养状况是健康生活的必然过程。与男性相比,女性更容易患贫血。根据世卫组织的报告,开发以草药为基础的配方来治疗贫血患者是安全且毒性较小的。在这项研究中,对66名年龄在20-30岁之间的女性贫血志愿者进行了阿育吠陀血液制剂Nabayas Louha (NBL)与g -铁叶酸(IFA)的双盲、跨组比较临床试验。结果显示,每天给药500毫克的NBL,连续30天显著增加了治疗志愿者的血红蛋白含量。使血清铁含量升高,总铁结合力降低。ESR水平也有所下降。发现NBL的这些影响与IFA相当。白细胞计数明显减少,但淋巴细胞计数有统计学意义的增加。此外,NBL处理组的毒性相关酶SGOT和SGPT水平没有显著改变,生动地证实了补充NBL是无毒的。综上所述,NBL可作为缺铁性贫血和白细胞紊乱的补充治疗。关键词:贫血;阿育吠陀;Haematinic;世界卫生组织(WHO);Nabayas louha (NBL);叶酸铁(IFA);红细胞沉降率;白细胞;谷丙转氨酶(GPT);血清谷草转氨酶(SGOT);血清谷丙转氨酶;总铁结合力(TIBC);缺铁性贫血(IDA)

The first article is by Saleh B et al [1]. Correlation between 2 plant hormone Abscisic acid (ABA) and hydroxy acid (SA) accumulation and transcript pattern of VvNHX1, VvABF1, VvAREB2, VvCBF4 and VvOSM1 genes concerned in grapevine (Vitis vinifera grape L.) adaptation against a pair of dS/m brine treatment for one,3 and five days exposure has been assessed in Baladi and Halawani cultivars and B41 rootstock grapevine. information discovered that VvNHX1, VvABF1, VvAREB2 and VvCBF4 transcript patterns were closely connected with activation of ABA level in Halawani cv. Whereas, VvABF1 and VvAREB2 transcript patterns were closely connected with activation of ABA level in Baladi cv. While, VvNHX1, VvABF1 and VvCBF4 transcript patterns were closely connected with activation of ABA level in B41 rootstock.
第一篇文章由Saleh B等人撰写[1]。以Baladi和Halawani葡萄品种和B41砧木葡萄为材料,研究了葡萄对dS/m盐水处理1、3和5 d的适应过程中2种植物激素脱落酸(ABA)和羟基酸(SA)积累与VvNHX1、VvABF1、VvAREB2、VvCBF4和VvOSM1基因的转录模式。资料发现,VvNHX1、VvABF1、VvAREB2和VvCBF4转录模式与海葵中ABA水平的激活密切相关。而VvABF1和VvAREB2转录模式与Baladi cv中ABA水平的激活密切相关。而vnhx1、VvABF1和VvCBF4转录模式与B41砧木ABA水平的激活密切相关。

Phycobiliproteins are photosynthetic antenna pigments of cyanobacteria and red algae, where they are assembled in macromolecular supercomplexes of phycobilisomes (PBS)s, as well as of cryptophyte algae, where they exist in the form of dimers. The absorbed light energy transfer from phycobiliprotein antenna to the photosystem II (PS II) is well known since the first studies in this field and is highly effective reaching 95-100%. However, interaction of phycobiliproteins with the photosystem I (PS I) is subject for discussion. Here, various data on energetic coupling of PBSs and phycobiliproteins with the PS II and PS I in photosynthetic organisms are discussed.
藻胆蛋白是蓝藻和红藻的光合天线色素,它们在藻胆异构体(PBS)的大分子超复合体中组装,以及在隐藻中以二聚体的形式存在。从藻胆蛋白天线到光系统II (PS II)的吸收光能传递自该领域的第一次研究以来就广为人知,并且效率很高,达到95-100%。然而,藻胆蛋白与光系统I (PS I)的相互作用尚待讨论。本文讨论了光合生物中叶绿素和藻胆蛋白与PS II和PS I能量耦合的各种数据。
