Researchers in Brazil found a special part of tomato genome that controls the size of not just the fruit but also the leaves and stems. This discovery could help making tomato crops more resilient to different...

The SAUR41 subfamily of genes is involved in cell expansion and salt tolerance
The SAUR41 genes are ABA inducible and active during seedling establishment.

Successive leaflets within the same tomato compound leaf are “cellularly” the same
The question of which cellular mechanisms determine the variation in leaf size has been previously addressed in plants with simple leaves. Dissecting compound tomato (Solanum lycopersicum) leaves in leaflet areas and in...

Evolution of nectar spur length in a clade of Linaria
Nectar spurs are tubular outgrowths of a floral organ that contain or give the appearance of containing nectar. They are hypothesized to be a ‘key innovation’ leading to rapid speciation within a lineage because they...
Heterogeneous growth of Arabidopsis leaf epidermis
The epidermis of an expanding dicot leaf is a mosaic of cells differing in identity, size and differentiation stage. Elsner et al. study leaves of Arabidopsis thaliana wild-type and triple cyclinD3 mutants and find that...

ERECTA gene and leaf cellular development
<i>ERECTA</i> gene and leaf cellular development The ERECTA gene plays a role in the balance between epidermal cell expansion and division in leaves. Tisné et al. perform spatial and temporal analyses of...
