A program library for use on open-source hardware was developed in order to construct a low-cost environmental control system for greenhouses. The library facilitated the development of environmental sensing and control devices that conform to the protocols of the Ubiquitous Environment Control System (UECS). The open-source hardware used was the "Arduino Ethernet" and the "Arduino Mega 2560 with Ethernet Shield" microcontroller boards. UECS is a system for controlling greenhouse environments that communicates information via a local area network, and devices utilizing the library that we developed can perform the UECS defined communication tasks automatically. With the help of this library, device developers no longer need to program the communications aspects of the device and can concentrate on programming setting and control logic of the device. The library occupies about 29 kilobytes of the read only memory area of the target board. The library and associated open-source microcontroller boards are powerful tools for developing low-cost environmental control systems.

This research reveals that the up-regulated expression of multiple capsaicinoid biosynthetic genes in pericarp tissue leads to the elevation of total capsaicinoid content in chili pepper fruit.
Capsaicinoids are health-functional compounds that are produced uniquely in chili pepper fruits. A high capsaicinoid level is one of the major parameters determining the commercial quality and health-promoting properties of chili peppers. To investigate the mechanisms responsible for its high contents, we compared an extremely pungent cultivar 'Trinidad Moruga Scorpion Yellow' (MY) with other cultivars of different pungency levels (Fushimi-amanaga, Takanotsume, Red Habanero). Capsaicinoid concentrations were markedly higher in MY fruit (23.9 mg/g DW) than in other pungent cultivars including 'Red Habanero' (HB) fruit (14.3 mg/g DW). Comparative analysis of MY and HB reveals that both cultivars accumulated similar capsaicinoid concentrations in the placental septum, with that in the HB pericarp (1.8 mg/g DW) being markedly lower than that in the placental septum (69.1 mg/g DW). The capsaicinoid concentration in HB fruit is dependent on the placental septum, as reported in other accessions. Therefore, even though placental septum tissue contains high capsaicinoid concentrations, those in the pericarp and seeds attenuated its total content. In contrast, the MY pericarp exhibited a markedly higher concentration (23.2 mg/g DW). A qRT-PCR analysis revealed that multiple capsaicinoid biosynthetic pathway genes (Pun1, pAMT, KAS, and BCAT) were strongly up-regulated in placental septum of pungent cultivars. The genes were expressed exclusively in the MY pericarp, but were barely detected in the pericarps of other pungent cultivars. Collectively, the present study indicates that the up-regulated expression of these genes not only in placental septum but also in pericarp plays an important role in driving capsaicinoid accumulation in the whole fruit.

Non-pungency in a Japanese Chili Pepper Landrace (Capsicum annuum) is Caused by a Novel Loss-of-function Pun1 Allele 査読

Pungency in peppers is due to the presence of the alkaloid capsaicin and its analogues, collectively known as capsaicinoids. These compounds are only produced in the Capsicum genus and function as deterrents to mammals from consuming the pepper fruits. Pungency in pepper is qualitatively controlled by the Pun1 locus, which encodes a putative acyltransferase enzyme. Mutations in the Pun1 gene result in a loss of pungency, and several Pun1 loss-of-function alleles have been identified in sweet peppers to date (pun1(1-3)). However, variations in pun1 alleles have not been completely elucidated. In the present study, we report a new type of loss-of-function pun1 allele, named pun1(4), in a Japanese sweet pepper cultivar, 'Nara Murasaki' (C. annuum). Sequence analysis at the Pun1 locus revealed that this type of Pun1 allele is caused by a single adenine nucleotide insertion in the second exon region. This insertion is unique to 'Nara Murasaki' and is not present in wild-type Pun1. This insertion causes a frameshift mutation and a change in the amino acid sequence, resulting in a truncated protein. The results of gene expression analysis indicated that the expression of Pun2 in 'Nara Murasaki' was hardly detectable, while the transcripts of this gene were strongly expressed in a pungent cultivar. In a co-segregation test, the pun1(4) genotype perfectly co-segregated with non-pungency in 103 F-2 population plants of a cross between 'Nara Murasaki' and a pungent cultivar. 'Nara Murasaki' and a DNA marker to distinguish the pun1(4) allele will be informative for understanding the domestication process of sweet peppers.

<p>高温期に育苗する暖地の晩秋～早春出荷作型において吸水種子湿潤低温処理によるトルコギキョウの切り花生産を可能にするため，ロゼット性の異なる品種への吸水種子湿潤低温処理の効果を再検証するとともに，処理後の育苗中の昼夜温が生育に及ぼす影響を調査した．吸水種子湿潤低温処理は，品種固有のロゼット性に関わらず抽苔率，発蕾率および開花率を高めた．また，吸水種子湿潤低温処理終了後の育苗夜温が28°Cおよび31°Cの場合，ロゼット性に関わらず抽苔率および開花率が低下したが，22°Cおよび25°Cでは抽苔率，発蕾率および開花率が高く，育苗夜温が低いほど，生育が促進されるとともに切り花長が大きくなった．さらに，育苗昼温が30°Cおよび40°Cでは，抽苔率，発蕾率および開花率に影響しないが，育苗昼温が低いほど生育が促進された．</p>
