In vitro regeneration of pea (Pisum sativum L.), a regeneration recalcitrant legume, was optimised using thidiazuron. Buds were initiated from the meristems of the cotyledonary nodes of embryo axes, isolated from mature seeds, and subcultured on Murashige and Skoog medium supplemented with 13.3 μM 6-benzylaminopurine, 16.1 μM α-naphthaleneacetic acid, and 0.2 μM 2,3,5-triiodobenzoic acid. Proliferation of buds was preceded by the formation of white nodular-like protrusions. These structures were cut transversally in fine slices and subcultured on the same medium or in presence of thidiazuron that produces a second wave of secondary budding. The best results (90–110 buds per expiant) were obtained with 10 μM thidiazuron. The capacity of regeneration was genotype independent and reproducible. Buds elongated on the initial medium, then formed roots in presence of 5.37 μM α-naphthaleneacetic acid. and developed into viable plants. Key words: Pisum sativum L., regeneration, meristems, embryo axes, thidiazuron.

In vitro regeneration of pea explants (Pisum sativum L. var. ‘Lincon’) was done in 49 different combinations and concentrations of BAP, BAP and NAA, BAP and IBA, TDZ, TDZ and Adenine for shoot regeneration from hypocotyl, root, leaf and cotyledonary node. High frequency shoot regeneration was obtained in hypocotyl (81.43%), root(83.53%) and cotyledonary node(72.76%) on MS medium supplemented with 4.50 mg/l BAP and 1.86mg/l NAA, 2.00mg/l TDZ and4.50 mg/l BAP and 1.86mg/l NAA respectively. No shoot regeneration was obtained from leaf explants on any of the combination used. Shoot elongation was observed on the same medium used for shoot regeneration respectively.MS medium supplemented with 0.20 mg/l IBA was found best for root regeneration from in vitro raised shoots. The plantlets were able to regenerate within 6-7 weeks. The regenerated plantlets were acclimatized in pre-sterilized cocopeat.

Pisum Sativum L

Pea (Pisum sativum L.) has been extensively used in early hybridization studies and it was the model organism of choice for Mendel’s discovery of the laws of inheritance, making pea part of the foundation of modern genetics. Pea has also been used as model for experimental morphology and physiology. However, subsequent progress in pea genomics has lagged behind many other plant species, largely as a consequence of its genome size and low economic significance. The availability of the genome sequences of five legume species (Medicago truncatula, Lotus japonicus, Glycine max, Cajanus cajan and Cicer aerietinum) offers opportunities for genome wide comparison. The combination of a candidate gene and synteny approach has allowed the identification of genes underlying agronomically important traits such as virus resistances and plant architecture. Useful genomic resources already exist and include several types of molecular marker sets as well as both transcriptome and proteome datasets. The advent of greater computational power and access to diverse germplasm collections enable the use of association mapping to identify genetic variation related to desirable agronomic traits. Current genomic knowledge and technologies can facilitate the allele mining for novel traits and their incorporation from wild Pisum sp. into elite domestic backgrounds. Fast neutron and targeting-induced local lesions in genomes (TILLING) pea mutant populations are available for reverse genetics approaches, BAC libraries for positional gene cloning as well as transgenic and in vitro regeneration for proof of function through gene silencing or over-expression. Finally, recently formed International Pea Genome Sequencing Consortium, holds promise to provide the pea genome sequence by 2015, a year of 150 anniversary of Mendel’s work.

Direct Shoot

An efficient in vitro regeneration system through direct shoot organogenesis was established for Murraya paniculata (L.) Jack (Orange Jessamine). Epicotyls, leaves, roots, and cotyledons from in vitro-germinated seedlings and several plant growth regulators (PGRs) were evaluated for their effects on plant regeneration. Longitudinally cut epicotyl segments were observed to be the optimal explants followed by uncut epicotyls (not longitudinally cut). Roots, leaves, and cotyledons were not suitable as explants as a result of little or no shoot induction. Adventitious shoot induction was enhanced by the addition of 6-benzyladenine (BA). The highest percentage of shoot induction (87%) and the greatest number of shoots per explant (12.7) occurred on Murashige and Skoog (MS) medium supplemented with 15 μM BA from longitudinally cut epicotyls followed by 5.2 shoots per explant from uncut epicotyls. Optimal concentration of gibberellic acid (GA3) for shoot elongation was observed to be 15 μM. Eighty-five percent of the regenerated shoots produced roots with an average of three roots per shoot on MS medium supplemented with 5 μM indole-3-butyric acid (IBA). Our protocol for direct shoot organogenesis can potentially lead to the development of a robust method for production of transgenic plants of M. paniculata through Agrobacterium-mediated genetic transformation.

Molecular Framework

Plant regeneration is essential for survival upon wounding and is, hence, considered to be a strong natural selective trait. The capacity of plant tissues to regenerate in vitro, however, varies substantially between and within species and depends on the applied incubation conditions. Insight into the genetic factors underlying this variation may help to improve numerous biotechnological applications that exploit in vitro regeneration. Here, we review the state of the art on the molecular framework of de novo shoot organogenesis from root explants in Arabidopsis, which is a complex process controlled by multiple quantitative trait loci of various effect sizes. Two types of factors are distinguished that contribute to natural regenerative variation: master regulators that are conserved in all experimental systems (e.g., WUSCHEL and related homeobox genes) and conditional regulators whose relative role depends on the explant and the incubation settings. We further elaborate on epigenetic variation and protocol variables that likely contribute to differential explant responsivity within species and conclude that in vitro shoot organogenesis occurs at the intersection between (epi) genetics, endogenous hormone levels, and environmental influences.
