Temperature-dependent fasciation mutants provide a link between mitochondrial RNA processing and lateral root morphogenesis.

Although mechanisms that activate organogenesis in plants are well established, much less is known about the subsequent fine-tuning of cell proliferation, which is crucial for creating properly structured and sized organs. Here we show, through analysis of temperature-dependent fasciation (TDF) mutants of Arabidopsis, (), , and (), that mitochondrial RNA processing is required for limiting cell division during early lateral root (LR) organogenesis. These mutants formed abnormally broadened (i.

A hot water extract of Chlorella pyrenoidosa reduces body weight and serum lipids in ovariectomized rats.

The effects of a hot water extract of Chlorella pyrenoidosa, which contains chlorella growth factor (CGF), on the body weight, serum lipids, and the bone mass were evaluated using an ovariectomized rat as a model for postmenopausal bone loss. Rats were divided into four groups: sham-operated (Sham), Sham given the CGF solution, ovariectomized (OVX), and OVX given the CGF solution, respectively. Administration of the extract to OVX rats suppressed the body weight gain.
