Microscale thermophoresis as a powerful tool for screening glycosyltransferases involved in cell wall biosynthesis

Sharma, Rita (Springer Nature, 2020-07)

Identification and characterization of key enzymes associated with cell wall biosynthesis and modification is fundamental to gain insights into cell wall dynamics. However, it is a challenge that activity assays of ...

No evidence for transient transformation via pollen magnetofection in several monocot species

Sharma, Rita (, 2017)

The development of rapid and efficient transformation methods for many plant species remains an obstacle in both the basic and applied plant sciences. A novel method described by Zhao et al. (2017) used magnetic nanoparticles ...

Gene Expression Dynamics in Rice Peduncles at the Heading Stage

Sharma, Rita (Frontiers, 2020)

Improving grain yield in the staple food crop rice has been long sought goal of plant biotechnology. One of the traits with significant impact on rice breeding programs is peduncle elongation at the time of heading failing ...

MicroRNA-mediated regulation of agronomically important seed traits: a treasure trove with shades of grey!

Sharma, Rita (Taylor & Francis, 2021-03)

Seed development is an intricate process with multiple levels of regulation. MicroRNAs (miRNAs) have emerged as one of the crucial components of molecular networks underlying agronomically important seed traits in diverse ...

Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass

Sharma, Rita (Springer Nature, 2021-01)

Long-term climate change and periodic environmental extremes threaten food and fuel security1 and global crop productivity2,3,4. Although molecular and adaptive breeding strategies can buffer the effects of climatic stress ...

Divergence among rice cultivars reveals roles for transposition and epimutation in ongoing evolution of genomic imprinting

Sharma, Rita (PNAS, 2021-03)

Parent-of-origin–dependent gene expression in mammals and flowering plants results from differing chromatin imprints (genomic imprinting) between maternally and paternally inherited alleles. Imprinted gene expression in ...

Genome-wide in silico analysis of long intergenic non-coding RNAs from rice peduncles at the heading stage

Sharma, Rita (Springer, 2021-10)

Long intergenic non-coding RNAs (lincRNAs) belong to the category of long non-coding RNAs (lncRNAs), originated from intergenic regions, which do not code for proteins. LincRNAs perform prominent role in regulation of gene ...

Insights into the molecular basis of hypergravity-induced root growth phenotype in bread wheat (Triticum aestivum L.)

Sharma, Rita (Elsevier, 2022-03)

Hypergravity is a condition where the force of gravity exceeds that on the surface of the Earth and can be simulated by centrifugation. Previously, a significant increase in root growth phenotype was observed when wheat ...

Spatiotemporal Regulation of CRISPR/Cas9 Enables Efficient, Precise, and Heritable Edits in Plant Genomes

Sharma, Rita (Frontiers, 2022-04)

CRISPR/Cas-mediated editing has revolutionized crop engineering. Due to the broad scope and potential of this technology, many studies have been carried out in the past decade towards optimizing genome editing constructs. ...

Grass Genome Evolution and Domestication

Sharma, Rita (Frontiers, 2022-04)

Since their last common ancestor more than 100 million years ago, the grasses (Poaceae) have experienced a complex evolutionary history (Prasad et al., 2011). Whole genome duplications (WGDs), inter-species hybridization ...

Transcriptome analysis reveals cell cycle-related transcripts as key determinants of varietal differences in seed size of Brassica juncea

Sharma, Rita (Springer Nature, 2022-07)

Brassica juncea is an important oilseed crop, widely grown as a source of edible oil. Seed size is a pivotal agricultural trait in oilseed Brassicas. However, the regulatory mechanisms underlying seed size determination ...

Regulation of multiple tip formation by caffeine in cellular slime molds

Singh, Shashi Prakash (Springer, 2012-08)

The multicellular slug in Dictyostelium has a single tip that acts as an organising centre patterning the rest of the slug. High adenosine levels at the tip are believed to be responsible for this tip dominance and the ...

The thyroxine inactivating gene, type III deiodinase, suppresses multiple signaling centers in Dictyostelium discoideum

Singh, Shashi Prakash (Elsevier, 2014-12)

Thyroxine deiodinases, the enzymes that regulate thyroxine metabolism, are essential for vertebrate growth and development. In the genome of Dictyostelium discoideum, a single intronless gene (dio3) encoding type III ...

Distinct Interaction Sites of Rac GTPase with WAVE Regulatory Complex Have Non-redundant Functions in Vivo

Singh, Shashi Prakash (Elsevier, 2018-11)

Cell migration often involves the formation of sheet-like lamellipodia generated by branched actin filaments. The branches are initiated when Arp2/3 complex [1] is activated by WAVE regulatory complex (WRC) downstream of ...

Cell–substrate adhesion drives Scar/WAVE activation and phosphorylation by a Ste20-family kinase, which controls pseudopod lifetime
