1 Overexpressing WHY2 increased starch granule numbers in chloroplasts of pericarp cells, showing a partially dry, yellowing silique and early senescence leaves. Starch WHIRLY 2 Arabidopsis thaliana
2 Accordingly, WHY2 protein could directly activate the expression of JMT and SAG29 (SWEET15) gene expression and repress SWEET11 gene expression in the nucleus, leading to alteration of starch accumulation and transport in pericarp cells. Starch WHIRLY 2 Arabidopsis thaliana
3 In contrast, loss of WHY2 decreased starch and sugar content in pericarp cells but promoted starch accumulation in leaves and seeds. Starch WHIRLY 2 Arabidopsis thaliana
4 In contrast, loss of WHY2 decreased starch and sugar content in pericarp cells but promoted starch accumulation in leaves and seeds. Starch WHIRLY 2 Arabidopsis thaliana
