An activation tagging screen in which the cauliflower mosaic virus 35S enhancer was inserted randomly into an Arabidopsis genome homozygous for the floral homeotic mutation apetala2-1 (ap2-1) resulted in a line (28-5) with extraordinarily wide, heart-shaped ovaries. The ovary of the 28-5 ap2-1 mutant shows an oval shape because of increased numbers of enlarged cells. When the ap2-1 mutation is ...

to evaluate the effect of seeding rate on important agronomic traits in three winter rapeseed (brassica napus l.) cultivars, two field experiments were carried out as split plot arrangement in a complete block design with three replications during 2006-2008 growing seasons. three rapeseed cultivars (okapi, modena and licord) and three seeding rates (6, 8 and 10 kg/ha)) were randomized in main p...

This paper reviewed the effects of insect pollination on yield parameters plants from family Brassicaceae presenting different breeding systems. Meta-analysis indicates that in both self-compatible and self-incompatible crop species, meta-analysis seed (Y), silique set (SQS), number siliquae/plant (NSQ), seeds/silique (NSSQ) increase when are insect-pollinated compared to there is no pollinatio...

Heterotrimeric G proteins have been implicated in a wide range of plant processes. These include responses to hormones, drought, and pathogens, and developmental events such as lateral root formation, hypocotyl elongation, hook opening, leaf expansion, and silique development. Results and concepts emerging from recent phenotypic analyses of G-protein component mutants in Arabidopsis and rice ar...
