“…Corms accumulate storage proteins and carbohydrates that are involved in the maintenance of the developing sporophyte, as well as in supporting the morphogenetic events that are required for Vegetative propagation. The deposition of corm storage products is under developmental control (Strauss et al, 1980;Wills et al, 1983); however, the mechanisms and genes that control storage product accumulation are not known.…”

We investigated gene expression patterns that occur during taro corm development. Two-dimensional gel electrophoresis identified severa1 different prevalent proteins that accumulate during corm development. Microsequencing studies indicated that some of these proteins are related to taste-modifying proteins, such as curculin and miraculin, and proteins found in other storage organs, such as sporamin and the Kunitz trypsin inhibitor. A curculin-encoding cDNA clone, designated as TC1, was identified that corresponds to a highly prevalent 1-kb corm mRNA. The TC1 mRNA accumulates during corm development, is more prevalent in corm apical than basal regions, and is either absent, or present at low concentrations, in other vegetative organs such as the leaf and root. In situ hybridization experiments showed that the TC1 mRNA is highly concentrated in corm storage parenchyma cells and is absent, or present in reduced concentrations, in other corm cells and tissues. Our results show that corm development is associated with the differentiation of specialized cells and tissues, and that these differentiation events are coupled with the temporal and spatial expression of corm-specific genes.

“…Tujuh karakter tersebut yang sering digunakan petani untuk membedakan antar aksesi (Maretta et al 2020). Perbedaan antar aksesi dapat dibedakan melalui keragaman beberapa karakter seperti bentuk daun, warna petiol dan arsitektur umbi (Strauss et al 1980). Aksesi NTT memiliki tipe berumbi tunggal (dasheen), sedangkan S-24 dan S28 memiliki tipe umbi utama dengan umbi samping (eddoe).…”

Perubahan iklim dan keberlanjutan merupakan tantangan besar dalam produksi pangan, yang didominasi sumber pangan biji-bijian yang rentan terhadap perubahan iklim. Sumber karbohidrat umbi dianggap lebih tahan dan mudah beradaptasi dengan tantangan tersebut. Talas merupakan salah satu potensi besar untuk memenuhi kebutuhan pangan dengan nilai gizi yang tinggi. Penelitian bertujuan untuk mengevaluasi pengaruh penambahan dosis bahan organik terhadap karakter morfologi talas, dan hubungan karakter morfologi dan umbi yang dihasilkan, serta menentukan dosis yang tepat untuk budidaya talas di Indonesia. Penelitian menggunakan rancangan acak lengkap faktor tunggal yaitu dosis bahan organik, dengan lima ulangan. Dosis bahan organik terdiri dari 4 taraf yaitu 0,25 kg tanaman-1, 0,5 kg tanaman-1, 0,75 kg tanaman-1, dan 1 kg tanaman-1. Bahan organik (BO) meningkatkan pertumbuhan vegetatif, umbi atribut dan produksi bibit. BO meningkatkan pertumbuhan vegetatif kuantitatif. Dosis sekitar 0,5 - 1 kg lubang-1 diidentifikasi sebagai dosis yang tepat untuk pertumbuhan vegetatif, umbi atribut dan produksi bibit talas. Ada korelasi positif antara pertumbuhan vegetatif, atribut umbi dan produksi bibit. Tinggi tanaman, ukuran daun, dan diameter batang sangat penting untuk menentukan perkembangan umbi, dan selanjutnya menyebabkan tingginya produksi bibit.

“…The raphide idioblasts and laticifers are scattered around through the ground tissues and the druse idioblasts are scattered in the vascular tissues (Sunell and Healey, 1979). The corm is highly variable in size, shape, hydration, colour and nutritive values (Strauss et al, 1980). Based on the corm morphology, the plant is botanically classified into two groups namely dasheen (Colocasia esculenta var.…”

Northeast India is rich in genetic diversity of horticultural crops and colocasia is one of the important crops. This region is rich in colocasia diversity for both cultivated and wild species particularly in jhum fields, homestead gardens, near water bodies, river banks, forests and road sides. Wide range of variability is observed in vegetative characters, corm and cormel characters, yield and quality characters. It is cultivated in jhum field as a mixed crop along with paddy and other crops like ginger, chilli, maize, turmeric etc. and in homestead garden, it is cultivated along with maize, cucurbits, chilli, King chilli, etc. The nutrient rich and gluten free tuber crop is an integral part of traditional cuisines of ethnic people of this region. All the plant parts of this ariod member are edible. Several traditional dishes have been prepared from leaves, petioles and tubers. The leaves, petioles and damaged tubers are also fed to pig and poultry. Recent past, the genetic diversity of colocasia is under threat due to urbanization, climate change, introduction of new crops, and pest and diseases and resulted in genetic erosion. The conservation of these vast gene pool is necessary.
