New microsome-associated HT-family proteins from Nicotiana respond to pollination and define an HT/NOD-24 protein family

HT-family proteins have been identified in Nicotiana, Solanum, and Petunia. HT-B-type proteins are implicated in S-RNase-based self-incompatibility, but the functions of other family members are unknown. Screening for cDNA sequences with an expression pattern similar to HT-B in Nicotiana alata revealed a new group of small HT-family proteins, designated HT-M. HT-M proteins resemble HT-B in several respects： their pistil-specific expression pattern is indistinguishable from HT-B, they pellet with a microsome fraction, and their abundance decreases after pollination. Unlike HT-B, there is no S-specificity to this response, and RNAi experiments show that HT-M proteins are not necessary for self-incompatibility. Identification of a third group of pistil-specific HT-family proteins helps better define the characteristics of the family and allowed identification of putative new family members. By searching the databases with only the most conserved HT- family sequence elements, the signal sequence and cysteine motifs, we identified nodulin-24-1ike proteins and several small glycine-rich proteins as putative HT-family members. Like HT-M and HT-B, nodulin-24 is membrane associated. We propose that the conserved features in HT-family proteins are important for targeting or modification and refer to the broader family that includes both HT- and nodulin-24-1ike proteins as the HT/NOD-24-family.

Influence of Additive Gas on Electrical and Optical Characteristics of Non-equilibrium Atmospheric Pressure Argon Plasma Jet

引用

Plasma Science and Technology 2011年第5期13卷 575-582页

Electrical and optical properties of an argon plasma jet were characterized. In particular, effects of an additive gas, namely nitrogen or oxygen, on these properties were studied in detail. The plasma jet was found to be of a glow-like discharge, which scarcely changed upon the injection of an additive gas, either directly or through a glass capillary. Optical emission spectroscopy characterization revealed that excited argon atoms were the predominant active species in this plasma jet. Metastable argon atoms were highly quenched, and N2（C3yIu） became the main energy carrier following nitrogen injection. When oxygen was added to the afterglow zone through a glass capillary, no significant quenching effect was observed and the number of oxygen atoms decreased with the increase in oxygen concentration. Finally, to demonstrate an application of this plasma jet, a high-density polyethylene surface was treated with argon, argon/nitrogen, and argon/oxygen plasmas.

AIM: To elucidate influencing factors of treatment response, then tolvaptan has been approved in Japan for liquid ***: We herein conducted this study to clarify the influencing factors in 40 patients with decompensated liver cirrhosis complicated by liquid retention. Tolvaptan was administered at a dosage of 7.5 mg once a day for patients with conventional diuretic-resistant hepatic edema for 7 d. At the initiation of tolvaptan, the estimated hepatic venous pressure gradient (HVPG) value which was estimated portal vein pressure was measured using hepatic venous catheterization. We analyzed the effects of tolvaptan and influencing factors associated with treatment ***: Subjects comprised patients with a median age of 65 (range, 40-82) years. According to the Child-Pugh classification, class A was 3 patients, class B was 19, and class C was 18. Changes from the baseline in body weight were -1.0 kg (P = 2.04 × 10-6) and -1.3 kg (P = 1.83 × 10-5), respectively. The median HVPG value was 240 (range, 105-580) mmH2O. HVPG was only significant influencing factor of the weight loss effect. When patients with body weight loss of 2 kg or greater from the baseline was defined as responders, receiver operating characteristic curve analysis showed that the optimal HVPG cutoff value was 190 mmH2O in predicting treatment response. The response rate was 87.5% (7/8) in patients with HVPG of 190 mmH2O or less, whereas it was only 12.5% (2/16) in those with HVPG of greater than 190 mmH2O (P = 7.46 × 10-4). We compared each characteristics factors between responders and non-responders. As a result, HVPG (P = 0.045) and serum hyaluronic acid (P = 0.017) were detected as useful ***: The present study suggests that tolvaptan in the treatment of liquid retention could be more effective for patients with lower portal vein pressure.

开黄花的金花茶C,Chrysantha(二倍体)与其他物种的种间杂交,在用种子培育杂交种植株上的尝试己被证明是不成功的在我们的杂交试验中,将越南山茶(六倍体)和金花茶进行五次人工控制授粉处理,成功地获得了含有三粒可育的种子的两个成熟蒴果。将这些可育的种子的成熟子叶置于BA3mg/L+NAA1.0mg/L的MS培养基上进行离体培养,经过六个月时间的缓慢增殖,把它转移到椰乳10％+GA_3 1mg/L的MS培养基上,子叶表面形成大量的浅黄色或浅绿色的芽点。这些发生出来的芽只有4.3%(6/138)形成5厘米以上的带叶小植株发育成苗。由根的分生细胞的核形态特征可以看出,这此新生植株是越南山茶和金花茶的杂交种。
