Karakterisasi Isolat Rhizoctonia SP. Patogenik Dan Rhizoctonia Mikoriza Pada Tanaman Anggrek Tanah Spathoglottis Plicata
No full textRhizoctonia mikoriza merupakan jamur yang mampu berasosiasi dengan anggrek tanah. Selain
sebagai mikoriza, terdapat isolat Rhizoctonia sp. patogen dan penyebab penyakit busuk akar
pada Spathoglottis plicata. Penelitian ini bertujuan mengetahui perbedaan antara Rhizoctonia
sp. patogen dan Rhizoctonia mikoriza secara morfologi dan molekular menggunakan teknik
RAPD. Hasil penelitian secara morfologi menunjukkan bahwa warna koloni, panjang dan
jumlah inti sel isolat Rhizoctonia sp. patogen dan Rhizoctonia mikoriza pada S. plicata tidak
berbeda, tetapi berbeda pada ketebalan sel dan pengelompokan isolat berdasarkan uji
anastomosis hifa. Teknik molekuler RAPD menunjukkan bahwa setiap isolat Rhizoctonia sp.
patogen dan Rhizoctonia mikoriza memiliki perbedaan pada struktur DNA

No full textIn vitro culture of orchids has been developed for many purposes. Some native orchids and commercial orchid hybrids are propagated using seed germination or cut explants such as leaves, shoot tips, and roots to produce large numbers of orchid plantlets. This technique is widely used for the purpose in conservation of natural orchid species and industry of commercial orchid hybrids. However, the molecular genetic mechanism behind growth and development of these orchids during in vitro culture is still unclear, and needs to be elaborated. Recent advanced in transgenic technology in orchid is very helpful for studying the mechanism of action of key genes in various stages of orchid development during in vitro culture. In this review, an attempt to understand the role of class-1 KNOX gene and its relationship with other genes in the initiation of shoot apical meristem (SAM) for shoot development from orchid protocorm (a tubercle of developing orchid embryo) and PLBs (Protocorm Like Bodies) during in vitro culture will be discussed. It will answer the question about how the shoot formation can be controlled during growth and development of orchid cells in in vitro culture. Key words: In vitro, orchids, shoot development, KNOX, transgeni
