The big picture: using wildflower strips for pest control

Smita leads research in seed developmental biology. She also heads the Bioimaging facility at Rothamsted Research. Smita has more than 20 years’ experience in live-cell imaging and molecular genetics with a particular interest in using cell imaging technologies to address developmental questions. She aims to identify genes and resolve mechanisms controlling seed development and associated traits affecting final yield in the model plant, Arabidopsis and related Brassica crop species. She has uncovered specific mechanisms that regulate seed size in the Brassicaceae, which include timing of endosperm cellularisation (controlled by MADS box transcription factors). However, overall seed size and yield are constrained by source-sink relationships, the “seed size-seed number trade-off” paradigm, and this is the focus of her research. Smita is investigating the genetic and developmental control of ovule initiation in Arabidopsis. In a current project, her team is manipulating the expression of specific genes in early gynoecial development in Arabidopsis, in an effort to increase ovule primordia number with a view to increasing seed yield. Smita aims to combine genomic tools, predictive biology and high throughput phenotyping to link genotype to phenotype across multiple reproductive traits in Brassicas.
