 The efficiency of in vitro regeneration of four clones of Populus euramericana , Canada blanc , Eugenii , I - 45 / 51 , and Wisconsin # 5 , was examined . Cytokinins and the combinations with auxins affected the rate of regeneration from the explants of root segments , stem internodes , and leaf discs . Overall , BA and the combination with auxins were effective in root segments and leaf discs of the Canada blanc clone , whereas zeatin and the combination with auxins were important in stem internodes of the Wisconsin # 5 clone . The highest number of shoots averaging 17 . 6 $\ pm $ 0 . 47 from root segments in the Canada blanc clone , 18 . 2 $\ pm $ 3 . 0 from stem internodes in the Wisconsin # 5 clone , and 17 . 8 $\ pm $ 1 . 92 from leaf discs in the Canada blanc clone were obtained with 2 . 0 mg / 1 BA , 2 . 0 mg / l zeatin combined with 0 . 2 mg / l IAA , and 0 . 5 mg / l BA combined with 0 . 05 mg / l 2 , 4 - D , respectively . In particular , the addition of 2 , 4 - D into cytokinin medium promoted shoot proliferation .

 Intraspecific genetic diversity of sixteen accessions of Mogolian Alliums including fifteen species was investigated using randomly amplified polymorphic DNA ( RAPD ) analysis . Twenty three out of forty primers revealed scorable polymorphism . A total of 440 RAPD markers were generated on the 16 accessions of Mongolian Alliums . Among 440 RAPDs assayed , 439 were polymorphic with a mean polymorphic rate of 99 . 7 %. Unweighted pair - group method using an arithmetic average ( UPGMA ) cluster analysis using RAPD data separated the 16 Allium accessions into two broad groups at similarity index 0 . 70 . The clustering of the species was closely related with previous classification between A . altaicum and A . fistulosum . In addition , a high genetic similarity was showed between A . cepa and A . tagar .

 Four major naturally populated areas around the Jindong valley in Inje - Gun , Gangwon province for wild Pyrus ussuriensis , Malus sieboldii , and Malus baccata are mostly located on the southeast side of the mountains at 630 - 745 m in altitude at sea level and are in very good sunny areas . The total of 77 taxa dividing into 32 families , 58 genera , 65 species , and 12 varieties has been inhabited in these areas . Most of these plants are heliophytes , which love sunshine , but some of rhizo - plants such as Sasa borealis , climbing plants such as Actinidia arguta and Celastrus orbiculatus , or naturalized plants like Bidens frondosa are also shown . These areas have been continually destroyed , so it is possibly thought that the second transition has been progressed . The index of species diversity of plant groups in these areas is 0 . 672 ∼ 1 . 465 based on the Shannon - Wiener ' s method , but its index for the area that rhizo - plants like Sasa borealis are growing as an under planting decreases relatively . In this study , the oldest plant of Pyrus ussuriensis in Korea , which is 120 cm in diameter at breast height ( DBH ) , 19 m in tree height and 25 m in width , has been found .

 This study was conducted to investigate the $\ beta $ - glucan contents and their characteristics of winter cereals according to particle sizes and milling recoveries . Sieved fractions differed in their average contents of $\ beta $ - glucans , and the coarse fraction had higher contents of $\ beta $ - glucan than finely milled fractions . In all winter cereals , the $\ beta $ - glucan contents of raw flours were higher than those of their brans , and the highest $\ beta $ - glucan contents of every cereals were observed at 100 mesh > or 100 - 140 mesh fractions except the Chalssalbori fractions which showed the higest $\ beta $ - glucan contents ( 12 . 9 %) at 140 - 200 mesh fraction . As compared with the $\ beta $ - glucan content of Chalbori among the various milling recoveries , the $\ beta $ - glucan was distributed more evenly throughout the endosperm but $\ beta $ - glucan content in bran of Chalbori was only 1 . 5 %. However , $\ beta $ - glucan content of Chalssalbori ( hull - less waxy barley ) was the highest in the subaleurone region ( 8 . 2 %) and declined slightly toward inner layers of grain . This results suggest that $\ beta $ - glucan distribution between high ( Chalbori ) and low $\ beta $ - glucan barley ( Chalssalbori ) may explain the difference in milling performance of barley . On the other hand , $\ beta $ - glucan contents of two rye varieties ( Chilbohomil , Chunchoohomil ) were lower than those of two waxy barley varieties , and the higest $\ beta $ - glucan contents were observed at the 60 % milling recoveries . In all winter cereals , the L - values ( lightness ) of raw flours were higher than those of brans . And the L - values of barley varieties were higher than those of oat and rye varieties . As the particle sizes and milling recovery ratios were decreased , the L - value were increased . The a - values ( redness ) in brans of every winter cereals were higher than those of every particle size flours and every milling ratio fractions , and this tendency was observed in the b - values ( yellowness ) of every particle size of cereal flours . The L and b - value of barley , the b - value of oat , and L , a , b - value of rye have the significant relationship with the $\ beta $ - glucan contents , respectively . This results represent the fact that $\ beta $ - glucans affected the color of the flours and pounded grains of winter cereals .

 The wild Pyrus plants belong to the deciduous woody plants in Rosaceae family . Most are cultivated for fruit productions , but some for ornamental plants . There are 5 Pyrus species including Pyrus ussuriensis and 8 varieties cultivated in Korea . In Korea , these plants are populated near villages or on the hills , and they are easily propagated since their fruit are very juicy and quite big in size . Plant breeding to get improved cultivars is not difficult because the Pyrus plants are easy to cross breeding among its genus . Because not only this reason but there have been shown lots of variation in wild groups , the Pyrus plants inhabited in Korea are excellent deciduous woody plants and favorable fruit trees to develop ornamental plants . It is necessary to develop many kinds of fruit trees and ornamental trees containing genetically different character , so that it will be satisfied for many different people ' s taste and demands . Collecting lots of wild plant resource with diverse genes is necessary for plant breeding .

 A major portion of drugs used in Ayurvedic system of medicine which has been practiced since the early human civilization in Indian subcontinent were of plant origin . It should be noted that 70 % of the population in this region depends on Ayurveda for their medical treatment and 60 % of the drug resources are obtained from the Himalayan region . Therefore , Nepal becomes a potential source of plant drug resource since it occupies a major portion of the Himalaya . In the present paper , in general a current status of medicinal plant resources of Himalayan region especially Nepal will be discussed . In addition to this , a typical example of antidiabetic activity of Shilajit will be taken for the discussion . Shilajit is one of the crucial elements in several formulations including those of Rasayana , a therapy in Ayurveda , which has been practiced in the prevention of ageing and mental disorder . Although , Shilajit is widely used for the treatment of diabetes , no satisfactory scientific reports are available up to now . The crude Shilajit in the market is a dark brown or black rock - like substance collected from the Himalayan region with a strong smell of cow ' s stale urine . In our studies , Shilajit ( collected in the central Himalayan region ) prevented the diabetes in nonobese diabetic ( NOD ) mice model . Shilajit also prevented the diabetes in the rats against the action of multiple low - dose ( 10 mg / kg , i . v . , 5 times ) of streptozotocin . On the other hand , Shilajit did not show antioxidative activity . The preventive action of Shilajit on diabetes is mainly focused on the Thl and Th 2 cell activities , since Th 2 cells activity was found to be significantly upregulated . Shilajit , however , showed a mild action in controlling the blood sugar level in young , old , and mild diabetic rats , but not in the severe diabetic rats . It also stimulated the nitric oxide production in macrophages . Based on these evidences , the antidiabetic activities of Shilajit appear to be immunomodulative probably by protecting or strengthening insulin - producing b - cells in the pancreas . Further systematic research on constituents of Shilajit and its quality evaluation is necessary to enable the use of natural medicines in the treatment of diabetes .

 We tried to introduce two forsythia genes related in lignan biosynthesis , dirigent protein and pinoresinol / lariciresinol ( Ph ) reductase , into potatoes for accumulation of lignans in transgenic potatoes . We made binary vectors overexpressing dirigent protein gene and P / L reductase gene driven by a CaMV 35 S promoter and transformed into potatoes via Agrobacterium mediated transformation . And in order to control the metabolic flux of lignan biosynthesis pathway , we tried to inhibit chalcone synthase genes of potatoes by antisense inhibition technique also . We tried to use PCR screening method for selection of transgenic plants of different vectors . We tried to determine and compare lignan contents from different transgenic potato lines .
