To maximize the economic benefits of Hyacinthus orientalis L., micropropagation and morphogenesis induction five cultivars were investigated under four different concentrations indole acetic acid (IAA) with two cytokinins, benzyl adenine (BA), or kinetin (Kin). Days for initiation shoot formation in red fewer than blue white cultivars. Blue showed an increase fresh weight chlorophyll content ei...

Poor seed germination is a major issue in teak (Tectona grandis) propagation. Teak dormancy thought to be the reason for delayed germination. So far, specific mechanisms have not yet been identified. In order study influence of presowing treatments on germination, seedling vigour, and biochemical attributes fresh drupes collected from production area Top Slip Tamil Nadu. The were subjected diff...

The mulberry tree (Morus alba) is a perennial and fast-growing distributed worldwide under different climatic conditions. Most of the world’s silk production (>90%) facilitated by feeding silkworm larvae on leaves alba L.) varieties. Therefore, exploration protocol for improving propagation efficiency increasing reproductive capacity M. varieties could be great significance. This study aimed...

The Arabidopsis chy1 mutant is resistant to indole-3butyric acid, a naturally occurring form of the plant hormone auxin. Because the mutant also has defects in peroxisomal -oxidation, this resistance presumably results from a reduced conversion of indole-3-butyric acid to indole-3-acetic acid. We have cloned CHY1, which appears to encode a peroxisomal protein 43% identical to a mammalian valine...

Genetic evidence suggests that indole-3-butyric acid (IBA) is converted to the active auxin indole-3-acetic acid (IAA) by removal of two side-chain methylene units in a process similar to fatty acid beta-oxidation. Previous studies implicate peroxisomes as the site of IBA metabolism, although the enzymes that act in this process are still being identified. Here, we describe two IBA-response mut...

Indole-3-butyric acid (IBA) is widely used in agriculture because it induces rooting. To better understand the in vivo role of this endogenous auxin, we have identified 14 Arabidopsis mutants that are resistant to the inhibitory effects of IBA on root elongation, but that remain sensitive to the more abundant auxin indole-3-acetic acid (IAA). These mutants have defects in various IBA-mediated r...
