Thesis title: “Studies on RNAi mediated resistance for the management of Mungbean yellow
mosaic India virus (MYMIV) in soybean”
Nature of work:
Soybean is highly proteinaceous among legumes and also good source of phosphorous, lecithin
and as well as water soluble vitamins. Soybean has importance in human dietary and industrial
use. Yellow mosaic disease (YMD) of grain legumes is a major constraint in the cultivation of
pulses and grain legumes in India. Yellow mosaic disease (YMD), the most destructive disease of
soybean, caused by the viruses belonging to the Genus Bogomovirus in the family Geminiviridae.
Yellow mosaic disease of soybean is caused by two viruses i.e. Mungbean yellow mosaic virus
(MYMV) and Mungbean yellow mosaic India virus (MYMIV). Viruses of family Geminiviridae have
typical geminate particle morphology, encapsidating single stranded circular DNA of 2.5 to 3.0 kb
1
in size as genome. The viruses of the genus Bogomovirus infect dicotyledonous plants and are
transmitted by whitefly (Bemisia tabaci Genn.). MYMIV have bipartite genome designated as
DNA-A and DNA-B, each of about 2.7 kb in size. Soybean cultivation was difficult in northern
India during 70s, because of YMD constraint. To exploit that potential, it is essential to overcome
productivity constraints of which YMD plays a major role. For control of YMD in soybean, the
pathogen should be identified, and managed by developing resistance variety. To achieve this
goal, following objectives have been framed in this study.
1. Survey, collection and maintenance of yellow mosaic virus isolates infecting Soybean.
2. Molecular cloning of replication initiation protein gene and intergenic region of the virus
isolates.
3. To study the variability among different isolates and identify the conserved region in the
replication initiation protein gene and intergenic region.
4. Development of RNAi constructs targeting replication initiation protein gene and intergenic
region.
5. To develop transgenic soybean plants with RNAi construct and their analysis.
The YMD infected leaves were collected from major soybean growing region of India. The
replication initiation protein gene (Rep, ORF AC1) and intergenic region (IR) were PCR amplified
using specific primer. The antisense construct of Rep gene and hairpin constructs for Rep and IR
region were made. Three Indian cultivars were transformed by agrobacterium-mediated
transformation and regeneration protocol standardized.
The salient findings of the study are summarized below:






Eight YMD infected samples were collected from different geographical region of India.
Primers have been designed for antisense Rep, hairpin construct of Rep and IR region on the
basis of conserved region.
Two RNAi construct targeting Replicase gene (ORF AC1, antisense and hairpin) and one
targeting intergenic region (IR, hairpin) of MYMIV-Sb was made in plant transformation vector
and confirming through sequencing. The efficiency of this RNAi construct was tested for
mitigation of disease by co-agroinoculation along with the infectious clones of MYMIV-Sb. In
the case of plants co-agroinoculated with RNAi construct, the symptom severity as well as the
percentage of infection was almost negligible, confirming the inhibition of disease
development by RNAi construct.
Transformation protocol was standardized for three Indian cultivars. Fourteen T1 lines were
confirmed for antisense Rep gene, thirteen T0 lines for hairpin Rep and eighteen T0 lines for
hairpin IR gene incorporation.
Bioassay experiment were performed for 176 T1 antisense Rep transgenic plants, 143 lines
were expressed resistant for the MYMIV.
RNAi construct made is effective against the virus inoculation. First in soybean, the proof of
concept of RNAi has been shown in this study.

Thesis title: “Population based study of Spinal Muscular Atrophy using PCR based RFLP”
Nature of work:
Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disease,
characterized by deletion in the exons 7 & 8 of SMN gene (188 bp and 187 bp respectively) of
the SMNt gene mapped on the 5q11.2 to 13.3 chromosome. A first time pilot study was
undertaken to asses SMA incidence in neonatal population of Indian using PCR based RFLP
analysis as a tool.
The salient findings of the study are summarized below:



DNA of blood samples from 67 neonates and 15 referred cases were analyzed for detection
exons 7 & 8 of SMNt gene. PCR of exons 7 & 8 of SMN gene and subsequent RFLP
standardized.
Of the 15 referred cases 3 were detected with deletion of 188 bp on exon 7 and 187 bp on
exon 8 of SMN gene. However no positive cases were detected in neonatal DNA studies.
The results of the study indicated that DNA analysis of larger neonatal population is required
for early detection, genetic counseling, prevention and therapy.
Current Research Profile:
Supervisor: Dr. Archana Sachdev
Currently working as Senior Research Fellow (15th February, 2012-Till date)
Project: “Use of RNAi technology in developing low phytate soybean and rice”.
Work place: Division of Biochemistry, Indian Agricultural Research Institute, New Delhi, India
Nature of work:
Cereal grains and oilseeds contain large quantities of phytic acid, which provides myo-inositol
and phosphorus required during seed germination and seedling establishment. Phytic acid has
a negative impact on animal nutrition and the environment. The otherwise nutritionally
adequate phosphorus content of cereal grains and oilseeds is bound in phytic acid and
therefore not available to monogastric animals that lack sufficient phytase in their digestive
tract for optimal phosphorous nutrition. ATP binding cassette (ABC) transporter is a key
contributor to phytic acid accumulation in soybean seeds. Phyitc acid level can be reduced by
silencing the ABC gene which engineer the dominant, seed specific block in phytic acid
accumulation.
Key Performance area:



RNAi construct were designed using ABC transporter gene to reduce the level of phytic acid in
developing seeds of soybean.
Agrobacterium mediated transformation using the RNAi construct and analysis of putative
transformants for gene incorporation.
Analysis the level of phytic acid by MegaZyme kit, modified colorimetric method and HPLC.

Bipolaris sorokiniana (teleomorph Cochliobolus sativus) is the causal agent of common root
rot, leaf spot disease, seedling blight, head blight, and black point of wheat and barley.

Total 113 isolates of spot blotch were collected from 6 zone and characterized by different
molecular markers. Many molecular markers is applied in the present study like RAPD, URP,
ISSR, ITS and RELP. After studying the result, the each zone are preparing separate cluster.

Work place: Fungal molecular and Plant pathology laboratory, Division of Plant Pathology, Indian
Agricultural Research Institute (IARI), Pusa Campus, New Delhi, India.
Key Performance area:

Trichoderma species have been investigated as biological control agents against Bipolaris
sorokiniana and Fusarium graminiarum. There morphological differences among different
species and isolates of the same species.

We used 27 Randomly Amplified Polymorphic DNA (RAPD)-PCR and ITS primers to estimate
genetic variation among isolates of Trichoderma reesei (2 isolates), Trichoderma viride (10
isolates), Trichoderma pseudokoningii (1 isolate) and Trichoderma harzianum (1 isolate).

Polymorphisms were found between species. RAPD analysis suggested that, two strains of
Trichoderma viride (T V 5-2 & 2211) and two other strains of Trichoderma viride (TCT-10 &
T2) are 88% same. Amplification of the ITS region produced a single band of approximately
600 bp for all the isolates. Although there was differences in branching between dendogram
derived from RAPD supported the distinction of 4 Trichoderma species, with the T. viride
isolates grouping together and showing differences at an intraspecific level.
