Serine carboxypeptidase (SCP) is one of the largest groups of enzymes catalyzing proteolysis for functional protein maturation. To date, little is known about the function of SCPs in rice. In this study, we present a comprehensive analysis of the gene structure and expression profile of 59 rice SCPs. SCP46 is dominantly expressed in developing seeds, particularly in embryo, endosperm and aleuro...

Studies were undertaken to elicit information to standardize the optimum dose and soaking period of bio growth regulators in rice seeds, to evaluate the effect of sources and method of application of bio-growth regulators (panchakavya and brassinolide) on organic rice seed during 2003 and 2004 and to assess the quality of rice seeds cv. ADT(R) 45). The results illustrated that, the combined use...

This paper analyzes optimal weed control management strategies under static and dynamic decision rules. Seed bank is taken into account to introduce dynamics into the model. We present a numerical example of controlling Sheathed Monochoria (Monochoria Vaginalis) in Korean rice paddy fields. Our results show that producers benefit from dynamic decision rules; higher income and more control of we...

background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...

Seed priming is a successful practice to improve crop establishment under adverse environment. However, reduced longevity of primed rice (Oryza sativa L.) seeds during storage limited the adoption of this technique. Present study investigated the effect of temperature, relative air humidity (RH) and oxygen on the longevity of primed rice seeds in a range of 60 days storage. In addition, the bio...

OsTZF1 is a member of the CCCH-type zinc finger gene family in rice (Oryza sativa). Expression of OsTZF1 was induced by drought, high-salt stress, and hydrogen peroxide. OsTZF1 gene expression was also induced by abscisic acid, methyl jasmonate, and salicylic acid. Histochemical activity of β-glucuronidase in transgenic rice plants containing the promoter of OsTZF1 fused with β-glucuronidase wa...

Seed germination capability of rice is one of the important traits in the production and storage of seeds. Quantitative trait loci (QTL) associated with seed germination capability in various storage periods was identified using two sets of recombinant inbred lines (RILs) which derived from crosses between Milyang 23 and Tong 88-7 (MT-RILs) and between Dasanbyeo and TR22183 (DT-RILs). A total o...

This paper presents a proposed expert to solve the problem of rice growers from seed to seed i.e from selection and sowing of varieties till harvesting of crop. Expert system is a collection of computer programs, developed for a particular area of domain that are capable of offering solutions or advices related to specific problem. An expert system is a problem solving & decision making system ...

High fat diet may cause obesity, diabetes, atherosclerosis, hypertension, hyperlipidemia and other diseases, even mortality. The recombinant rice based on mixing lotus seed starch broken flour was used to feed high-fat rats, its effects body weight organ index were determined. changes of intestinal flora in rats studied by macrogenomic technology, the starch-broken (LSBR) discussed. results sho...

We determined efficacy of AV-1011 (a 50% anthraquinone product; Arkion Life Sciences, New Castle, Delaware) on drill-planted rice seed to reduce blackbird damage and determine residue levels of anthraquinone (AQ) in rice seeds and seedlings and in the mature rice crop under field enclosures at the University of Missouri-Delta Center farm near Portageville, Missouri. Red-winged blackbird (Agelai...
