WebNov 17, 2016 · Key message Genes influencing seed size. Abstract The designation emp (empty pericarp) refers to a group of defective kernel mutants that exhibit a drastic reduction in endosperm tissue production. They allow the isolation of genes controlling seed development and affecting seed size. Nine independently isolated emp mutants have … WebJul 22, 2024 · Notably, increased cell death can lead to a dramatic lgp1 phenotype (i.e. reduction of all gluten proteins and starch, as well as partially empty pericarp) by two nonmutually exclusive mechanisms. In both plants and animals, severe or chronic ER stress can stimulate PCD to kill unwanted cells and protect others (Walter & Ron, 2011 ; Yang …
