Pengklonan gen-gen yang diinduksi oleh aluminium pada kedelai [Glycine max. (L) Merryl]
Cloning of aluminium induced genes in soybean [Glycine max (L)]
Abstract
Keracunan aluminium merupakan pembatas utama produksi pertanian di dunia, dan khususnya di daerah tropik seperti Indonesia, yang mempunyai areal tanah podzolik merah bersifat masam sekitar 47.6 juta hektar atau 32% dari total tanah masam di Indonesia. Sekitar 8% kandungan kerak lapisan bumi adalah logam aluminium dan pada umumnya berada dalam bentuk tidak larut (tidak tersedia) bagi tanaman. Tetapi, di bawah kondisi tanah masam (pH < 5), ion aluminium (Al) menjadi larut dan berpotensi sebagai penghambat bagi pertumbuhan tanaman khususnya organ/jaringan akar. Aluminium toxicity is a major factor limiting world agricultural production, particularly in the tropics such as Indonesia that has over 47,6 millions hectare of acidic soil. Aluminium (Al) comprises 8% of the earth's crust and is present in most soil as insoluble precipitates. However, under acid condition (pH < 5), soluble Al[3+] ions are released and are potent inhibitors of root growth. This research was conducted to support soybean breeding programmes by molecular approach. The aim of the current research is to identity Al-tolerant soybean varieties, to obtain Al induced genes and to increase our understanding of the nature of Al toxicity.
