“…Plant regeneration has been achieved in mulberry in vitro using meristem/shoot tip cultures, axillary buds, internodal segments, hypocotyl regions, cotyledons, and leaves, but the most widely used method of plant regeneration in mulberry is micropropagation through axillary bud culture ( Vijayan et al, 2014 , in a review). These studies have revealed that in vitro micropropagation in mulberry is dependent on the growth regulator combinations, explant type and most of the protocols are genotype specific and may not be applicable to all valuable genotypes ( Bhojwani, 1992 ).…”

Plant regeneration through rapid in vitro clonal propagation of nodal explants of Morus alba L. variety S-1 was established along with genetic stability analysis of regenerates. Axillary shoot bud proliferation was achieved on Murashige and Skoog (MS) medium in various culture regimes. Highest number of shoots (5.62 ± 0.01), with average length 4.19 ± 0.01 cm, was initially achieved with medium containing 0.5 mg/l N6-benzyladenine (BA) and 3% sucrose. Repeated subculturing of newly formed nodal parts after each harvest up to sixth passage, yielded highest number of shoots (about 32.27) per explants was obtained after fourth passage. Rooting of shoots occurred on 1/2 MS medium supplemented with 1.0 mg/1 Indole-3-butyric acid (IBA). About 90% (89.16) of the plantlets transferred to the mixture of sand:soil:organic manure (2:2:1) in small plastic pots acclimatized successfully. Genetic stability of the discussed protocol was confirmed by two DNA-based fingerprinting techniques i.e. RAPD (random amplified polymorphic DNA) and ISSR (inter-simple sequence repeat). This protocol can be used for commercial propagation and for future genetic improvement studies.

“…The natural range of white mulberry (Morus alba L.) is probably located in the central and western provinces of China and adjacent regions of Central Asia (western Tien Shan range, the region between the Amu Darya and Syr Darya rivers), where it has been widely cultivated for more than 4,500 years. The white mulberry was brought to Europe in the twelfth century in order to establish a functioning European sericulture since the leaves are the preferred food of the silk-producing caterpillars of Bombyx mori L. [1].…”

Morphometric and biochemical screening of old mulberry trees (Morus alba L.) in the former sericulture region of Slovenia

Over centuries, in many European countries, the white mulberry trees (<em>Morus alba</em> L.) became an integral part of the cultural landscape, bearing witness to past sericulture activities. The distribution records of white mulberry trees in the cultural landscape are incomplete and in general poorly documented. The aim of the presented research was to collect data regarding geographical locations of mulberry trees and to define their morphological and biochemical variability in Goriška region, one of the historical sericulture regions in Slovenia. Principal component analysis of all morphometrical leaf traits allowed us to characterize two separate groups of morphotypes. Recordings of the tree pruning management revealed that annual base cutting is traditionally used in Goriška region. Significant correlations between pruning management and leaf morphology traits showed that frequently pruned trees form larger leaves. Biochemically, mulberry leaves are shown to be rich in proteins containing threonine, arginine, asparagine, serine, and glutamine as the most prominent free amino acids. The main phenolic compounds were identified as caffeoylquinic acid derivatives, quercetin malonyl-hexoside, rutin, kaempferol acetyl-hexoside, quercetin-3-glucoside, and <em>p</em>-coumaric acid derivatives. The difference in concentrations of the investigated metabolites is correlated either with the pruning management or the morphotype. Pruning significantly affected the levels of asparagine, alanine, and serine, which were higher in the annually pruned trees regardless of the morphotype. Furthermore, we were able to confirm a significant effect of pruning on total phenolics as well as on the levels of rutin, quercetin malonyl-hexoside, and quercetin-3-glucoside contents. Multivariate analysis allowed us to determine seven chemotypes with distinctive biochemical traits. Our results are the basis for defining superior high-yielding genotypes with optimum metabolic composition for both silkworm feeding as well as for innovative usage in food processing and pharmaceutical industries.
