Expansins are cell wall proteins that mediate cell wall loosening and promote specific tissue and organ morphogenesis in plants and in some microorganisms. Unlike plant expansins, the biological functions of fungal expansin-like proteins have rarely been discussed. In the present study, an expansin-like protein-encoding fvexpl1 gene, was identified from Flammulina velutipes by using local BLAST. It consisted of five exons with a total length of 822 bp. The deduced protein FVEXPL1 contained 274 amino acids with a predicted molecular mass and isoelectric point of 28,589 Da and pH 4.93, respectively. The first 19 amino acids from the N terminal are the signal peptide. Phylogenetic analysis and multiple protein alignment indicated FVEXPL1 was an expansin-like protein. The expression level of fvexpl1 gene in the stipe was significantly higher than that in the mycelia, primordia, and cap. However, the expression level of fvexpl1 gene was significantly higher in the fast elongation region of the stipe as compared with the slow elongation region. Expression analysis indicated that fvexpl1 gene might have an auxiliary role in the stipe morphogenesis of F. velutipes.

The purpose of this study was to investigate if an community forestry programme (HKm) could be one of the main tool for REDD+ in Indonesia. Recently, considerable numbers of countries including Norway, England, Korea and etc. have invested 69 million US$ in total to Indonesia for implementation of REDD+. However, forest dependent people without a communal right are subject to poor forest governance during a stream of REDD+ in Indonesia. This study suggest that HKm are needed to be a tool for REDD+ in order to achieve the objects of REDD+ in terms of Equity, Efficiency, and Effectiveness (3Es) by stimulating local and Indigenous peoples to participate in REDD+. As a result of our study, Indonesia government have designated only 200,000 ha for HKm area by 2007. Indonesia government have a week political will to extend its area to give a communal right to those peoples who dwell in state forests and HKm application process is complicated and slow. HKm has a potential to be main tool for REDD+ in Indonesia. However HKm will be difficult to be main tool for REDD+ without resolving current obstacles.

Background: Humbo Farmer Managed Natural Regeneration (FMNR) forest is managed through direct involvement of the local community and funded by the World Vision Australia through World Vision Ethiopia under framework of the Kyoto Protocol's Clean Development Mechanism on greenhouse gas emissions. Understanding the amount and distribution of carbon stored in forests across different elevations will enhance ability to anticipate how forests will react to future climate conditions and carbon levels. The aim of the study was to quantify the amount of carbon stocks along altitudinal gradients in the Humbo FMNR forest in southern Ethiopia. A total of 54 nested sample plots of 20 m × 20 m were established on transects of elevation gradients. Inventories of woody species and soil samples (0-10 cm and 10-20 cm depth) were collected within each nested sample plot. Carbon stocks in woody biomass and soil were compared by three elevation classes. Results: The total carbon stocks significantly (p < 0.05) differed among the three altitudinal gradients. There is no significant difference in biomass carbon stocks between the middle (1,610-1,750 m above sea level [a.s.l.]) and lower (1,470-1,610 m a.s.l.) elevations. However, both of these elevations significantly differ (p < 0.05) from the higher (1,750-1,890 m a.s.l.) elevation, despite an increase in carbon stocks from lower to higher elevations. The highest ecosystem carbon stock was contributed by soil carbon. The higher proportion of C stocks at the higher elevations may be associated to the species composition and dominance with larger wood density. Conclusions: It was concluded that even though soil carbon contributed higher carbon to the total carbon stock, biomass is stronger impact than soil carbon when it comes to carbon stock variation by altitudinal gradients. We recommend that carbon-related awareness creation on reducing emission for the local people and promotion of knowledge on carbon stock credits accounting and to be claimed in future for financing, which could be considered as additional possible option for sustainable forest management.

Mushroom has economic, food and medicinal value to a large proportion of human populace. This study assessed the consumption pattern of mushroom species in Southwestern Nigeria. Non-probability sampling method was used to select 20 Local Government Areas (LGAs) from 3 states and four communities were selected purposively from each LGAs. Snow-ball sampling approach was used in selecting 5 respondents from each community, making a total of 400 respondents. Descriptive statistics was used to describe the socio-economic characteristics of the respondents, to compare the differences between the local (wild) and Exotic (cultivated) mushroom Species and to determine the rate at which mushroom substitute is consumed among the mushroom consumers. Logit regression was used to identify the factors influencing mushroom consumption in the study area. Thirty percent of the respondents were aged 41 to 50 years, with mean age of 49.76 years. About 82% had tertiary education, 17.3% earned above N200,000 monthly and 8.8% spent above N6000 monthly on mushroom. Logit regression showed that age (-3.21), household size (-2.17) and medicinal benefits (-2.17) had significant (p<0.01) negative effects on mushroom consumption. Conclusively, mushroom has wide acceptance among the general populace, good for food and medicine; hence, awareness should be created through agricultural policy on the need for mushroom cultivation and consumption in Nigeria.

The objective of this research was to evaluate physical and mechanical properties of three species of Styrax woods from North Tapanuli in Indonesia. The woods were more than 15 years old. Physical properties such as specific gravity, green moisture content, and volume shrinkage were determined by the procedures based on BS-373 standard for small clear specimen. Furthermore, mechanical properties, including modulus of rupture, modulus of elasticity, compression parallel to grain and hardness were also tested according to the standard. Along the stem direction, the edge section had better properties compared with those near the pith section. And the base section had also better properties than upper section. Based on the specific gravity, all of the Styrax woods in this research were classified into III-IV strength classes. A good dimensional stability was demonstrated by the value of the tangential and radial ratio which reached one. With the consideration of the mechanical properties, Styrax woods were suitable use for raw materials of light construction, furniture and handy craft.

This study proposed the introduction of the block grant in agriculture, forestry, and fishery sectors so that the local governments get greater autonomy in agricultural policy. First of all, theoretical background on block grant was reviewed and present situation in Korea regarding block grant was examined. Four criteria were set to evaluate the eligibility for the block grant. Four criteria imply that block grant is more appropriate with small-scaled similar projects, high locality projects, easily evaluated projects, and easily formula-applied projects. Applying these criteria to the projects subsidized by the national government, appropriate projects as the block grant were selected. Finally, specific operation scheme of the block grant was proposed.

Recently, the number of people who return to rural areas for farming is increasing rapidly. This attracted public attention so that the Ministry of Food, Agriculture, Forestry and Fisheries announced officially comprehensive countermeasures to help those returning to rural areas. But there is not sufficient consideration of the role of local governments in the above countermeasures. Policy package to help returning people establish themselves in rural area include many soft programs that requires governance, delicate implementation process and expertise to advise. Therefore, the local governments should have appropriate governance and perspectives.

This study aimed to categorize mountain villages according to business expense investments and investigate residents' supplementation demands and differences between expected effects by the categories. For the study, 35 villages where are completely developed on and after 2007 were selected to consider fairness among local governments. Each village leader(the head of the village or the chairperson of the management committee) was conducted a survey from 2012 May to August and one copy of survey was eliminated from the study. The study is summarized into four results. First, the types of mountain villages were categorized as a type of mountain village practice(18), a type of life environment improvement(8) and a type of forestry income(8) according by the itemized reports of the business expense investments. Second, the result of F-test(One Way ANOVA) for the average analysis by types showed that 3 out of 6 demands for the operation were significant differences and a supplementation necessity of the program was identified significant differences in p<0.01 level. The necessity of forestry resources use and sprawling development prevention are also showed significant differences among types in p<0.05 level. Third, F-test results from 7 questions of desired effects through mountain village creation project revealed that promotion and market security of forestry products and local patriotism instillation through a personal exchange are significant differences between types in p<0.05 level. Forth, the results of duplication benefits(the mountain village development projects and the village support programs with other departments) on the residents' development expectation found that when a village received a large number of projects, residents' expected effects were higher than other village residents where received relatively a small number of projects. However, the expected effects from the increasing quantities of projects were decreased.
