The branched-chain amino acid transaminases （BCATs） have a crucial role in metabolism of the branched-chain amino acids leucine, isoleucine, and valine. These enzymes catalyze the last step of synthesis and the initial step of degradation of these amino acids. Although the biosynthetic pathways of branched chain amino acids in plants have been extensively investigated and a number of genes have been characterized, their catabolism in plants is not yet completely understood. We previously characterized the branched chain amino acid transaminase gene family in tomato, revealing both the subcellular localization and kinetic properties of the enzymes encoded by six genes. here, we examined possible functions of the enzymes during fruit development. We further characterized transgenic plants differing in the expression of branched chain amino acid transaminases I and 3, evaluating the rates of respiration in fruits deficient in BCAT1 and the levels of volatiles in lines overexpressing either BCAT1 or BCAT3. We quantitatively tested, via precursor and isotope feeding experiments, the importance of the branched chain amino acids and their corresponding keto acids in the formation of fruit volatiles. Our results not only demonstrate for the first time the importance of branched chain amino acids in fruit respiration, but also reveal that keto acids, rather than amino acids, are the likely precursors for the branched chain flavor volatiles.

American Journal of Plant Sciences 2016年第10期7卷 1478-1489页

Red clover (Trifolium pratense L.) is a legume forage abundant in phenolic compounds. It tends to brown when cut for hay, due to oxidation of phenolic compounds catalyzed by polyphenol oxidase (PPO), and subsequent binding to proteins. Selecting for a greener hay may provide information about the relationship of browning, PPO, and phenolics to each other. The red clover Kenland cultivar was selected over eight breeding cycles for decreased browning after being cut and dried 48 h in the field. Expression of PPO1 and PPO3, in Kenland and three of the eight cycles, was compared by real-time quantitative PCR. Phenolic compounds in Kenland and Cycle 8, collected 0, 24, and 48 h after cutting, were quantified by h.g.-performance liquid chromatography (hPLC). Visual browning scores decreased 12% between Kenland and Cycle 8 (P = 0.02). PPO1 and PPO3 gene expression were not affected by selection. Clovamide decreased 26% in Cycle 8 relative to Kenland (P = 0.016). Sissotrin decreased 10% in Cycle 8 (P = 0.043). Neither total formononetin nor total biochanin A was affected by selection (P = 0.63 and 0.45, respectively). These results suggest that when selecting clover for decreased postharvest browning, a decrease occurs in a phenolic compound that can bind protein independently of PPO. however, PPO1 and PPO3 gene expression, and the major red clover isoflavones, are minimally affected.

Ultrasound (US) is often the first imaging modality employed in patients with suspected focal liver lesions. The role of US in the characterisation of focal liver lesions has been transformed with the introduction of specific contrast media and the development of specialized imaging techniques. Ultrasound now can fully characterise the enhancement pattern of hepatic lesions, similar to that achieved with contrast enhanced multiphasic computed tomography (CT) and magnetic resonance imaging (MRI). US contrast agents are safe, well-tolerated and have very few contraindications. Furthermore, real-time evaluation of the vascularity of focal liver lesions has become possible with the use of the newer microbubble contrast agents. This article reviews the enhancement pattern of the most frequent liver lesions seen, using the second generation US contrast media. The common pitfalls for each type of lesion are discussed. The recent developments in US contrast media and specific imaging techniques have been a major advance and this technique, in view of the intrinsic advantages of US, will undoubtedly gain popularity in the years to come.

Reviewed are the present status and future prospects of the laser fusionresearch at the ILE Osaka. The gekko XII and Peta Watt laser system have been operated forinvestigating the implosion hydrodynamics, fast ignition, and the relativistic laser plasmainteractions and so on. In particular, the fast ignition experiments with cone shell target havebeen in progress as the UK and US-Japan collaboration programs. In the experiments, the implodedh.g. density plasmas are heated by irradiating 500 J level peta-watt laser pulse. The thermalneutron yield is found to increase by three orders of magnitude by injecting the peta-watt laserinto the cone shell target. The Rayleigh-taylor instability experiment results are also reviewed isthis paper.
