Titled: Production of solanum elaeagnifolium alkaloids ‘in vitro’ using plant tissue
culture techniques.
Abstract:
The present investigation was conducted to produce alkaloids of Solanum
elaeagnifolium using tissue culture techniques, which included: hairy roots cultures using
Agrobacterium rhizogenes strain ATCC 15834, callus cultures and regenerants.
The highest values of total steroidal alkaloids (TSA) (32.62 mg / g DW) and solasodine
(18.98 mg / g DW) were found in the fruit of the wild plant; much lower values were
recorded in other organs. Diosgenin was detected only in the roots (0.121 mg / g DW).
High values of TSA (10 mg / g DW) and solasodine (7.924 mg / g DW) were produced
from hairy roots developed on shoot explants infected with half strength MS medium
supplemented with bacteria and 10 ml acetosyringone. Diosgenin level was about 0.4
mg / g DW. Callus induction was performed using M2 medium (MS + 0.5 mg / L 2,4-D +
1.0 mg / L KIN) for root (R), hypocotyl (Hy), stem (St) and leaf (L) explants.
Effect of abiotic stresses (sodium chloride and mannitol); biotic stress (Aspergillus niger
extract) and some additives (cholesterol and reduced glutathione) were studied.
3
Among callus cultures, the highest production of TSA (9.6 mg / g DW) was recorded in
St- and Hy-calli treated with 15 mM cholesterol, followed by (8.978 or 8.224 mg / g DW)
in R-calli treated with 40 % fungal extract or 0.05 M NaCl, respectively. Then came
L- and R-calli treated with 0.3 mM GSH (5.952 and 5.503 mg / g DW) and Hy-calli
treated with 0.11 M mannitol (5.032 mg / g DW). Regarding solasodine, St- and Hy-calli
treated with 15 mM cholesterol gave high values (4.582 and 4.265 mg / g DW,
respectively). Regarding diosgenin, the highest production (7.744 mg / g DW) was in
R-calli treated with 40 % fungal extract, followed by St-calli treated with 0.05 M NaCl
(3.049 mg / g DW). Regenerated shoots derived from apical shoot meristem contained
2.619 mg / g DW of TSA, which included equal amounts of solasodine and diosgenin
(about 0.55 mg / g DW). Regenerated plantlet and rooted-calli derived from
Hy-explants showed slight variation of TSA (2.429 and 2.835 mg / g DW, respectively).
The value of solasodine was higher than diosgenin in case of regenerated plantlet, while
the reverse was obtained in case of rooted-calli.
Ph.D., July, 2012 (Botany, Cytology, Genetics and Plant Biotechnology), Faculty of
Science, Cairo University, Egypt.
Titled: Improvement of fungal disease resistance in potato using Defensin gene and in
vitro selection.
Abstract:
Pathogenicity test showed that potato plants were highly susceptible to pathogenic
fungi Rhizoctonia solani, Fusarium dimerum, F. oxysporum, Cladosporium herbarum
and Nigrospora sphaerica. The maximum number of harvested tubers was found in case
of R. solani, while heavier tubers were in case of F. dimerum, F. oxysporum, N.
sphaerica and C. herbarum. The maximum number of tuber eyes was obtained in case of
C. herbarum. Nigrospora sphaerica and C. herbarum expressed wide variation in shapes,
colors and texture of tubers. The light microscopic observations showed changes in the
uppermost coat thickness and texture in all infected tissues compared with control.
Hypodermal tissue of infected tubers showed either hyperplasia in case of R. solani and
4
F. dimerum or hypertrophy in case of F. oxysporum and C. herbarum. Most of the
infected tissues showed the presence of many cytoplasmic vacuoles in hypodermal and
cortical layers with the presence of few starch grains in the cortical cells compared to
those present in the non-infected tuber. Transmission electron microscopy investigations
showed cell wall and cytoplasmic changes and/or degradation, together with membrane
abnormalities. Most of the infected cells showed the deposition of densely opaque
granular material along the plasma membrane and/or tonoplast in addition to dark
inclusions and crystals. Microtuberization reached about 94% on Islam et al. medium
after 10 days. Multiple shoot regeneration from tuber discs (6.1±1.9) were enhanced on
Jarret et al. medium while Yee et al. medium was more efficient in case of leaf explants
(2.6±1.2) so; both media and explants were used in transformation experiments. RAPD
analysis was used to detect similarities or dissimilarities between the normal in vitro
plantlet and the regenerants. The in vitro plantlets were used as source of explants for
transformation and in vitro selection experiments. The tuber discs and leaf explants were
co-cultivated with Agrobacterium tumefaciens on regeneration medium supplemented
with acetoseryngone for 2 days then transfer to selection medium. The putative lines and
control plantlets were subjected histochemical analysis and specific PCR to confirm the
insertion of defensin gene and Gus reporter gene in them. In vitro selection was carried
out and only nodal cuttings exposed to successive rising of the concentration of the N.
sphaerica and C. herbarum exhibited resistance. In vitro plantlets, selected and
transformed lines were acclimatized. Resistance bioassay showed absence of symptoms
on transformed organs and some mild symptoms on the foliar lamina, tubers and calli of
the selected lines when exposed to N. sphaerica and C. herbarum infection units,
compared to those of in vitro plantlet. In vivo test showed that in vitro plants became
wilted with fragile leaves when exposed to R. solani, F. dimerum or F. oxysporum. In
case of N. sphaerica, no symptoms were seen, while in case of C. herbarum, the leaves
showed necrosis spots. Highest reduction in the external symptoms was observed in
transformed lines compared to the in vitro selected plantlets and in vitro plantlets.
