for determining the oil content, seed and fruit characteristics of ethiopian jatropha provenances, the study was conducted in five regions of ethiopia namely southern nation nationalities peoples regional state, amhara region, tigria region, oromia region and benishangul gumuz regions, where jatropha is found abundantly. a total of 23 zones, 36 weredas and 40 sampling sites were considered from...

In order to investigate the effect of OsAAP1 gene mutation on chalkiness traits rice endosperm and microstructure starch granules in endosperm, we used mutants as experimental materials, with help ordinary optical microscopes scanning electron microscopes, morphological structure arrangement Zhonghua 11 were observed controls. The results showed that rate, area degree significantly increased, s...

Maize (Zea mays) endosperm consists of an epidermal-like surface layer of aleurone cells, an underlying body of starchy endosperm cells, and a basal layer of transfer cells. To determine whether surrounding maternal tissues perform a role in specifying endosperm cell fates, a maize endosperm organ culture technique was established whereby the developing endosperm is completely removed from surr...

The nuclear endosperm of monocots, including the cereal species maize, rice, barley, and wheat, represents humankind’s most important renewable source of food, feed, and industrial raw materials. In addition, the endosperm is an attractive system for developmental biology studies. Similar to the embryo, the endosperm is the result of a fertilization process and therefore may be considered an or...

Seed development in angiosperms demands the tightly coordinated development of three genetically distinct structures. The embryo is surrounded by the endosperm, which is in turn enclosed within the maternally derived seed coat. In Arabidopsis, final seed size is determined by early expansion of the coenocytic endosperm, which then cellularises and subsequently undergoes developmental programmed...

It is unclear how embryo size is genetically regulated in plants. Since cereals have a large persisting endosperm, it is expected that embryo size is affected by endosperm development. Nine single recessive mutations, four reduced embryo mutations representing three loci, REDUCED EMBRYO1, REDUCED EMBRYO2 and REDUCED EMBRYO3, four giant embryo mutations derived from a single locus GIANT EMBRYO, ...
