Abstract:
In the dry areas of Northwest China, cavity planters with vertical insertions are used for seeding on film. Due to the uncertain mechanism between cavity planters and maize seeds and soil, research on the cavity planter has been slow. Several theoretical and experimental methods have been developed to investigate the interaction between the cavity planter and maize seeds in soil. These methods enable exploration of the mechanism to reduce soil disturbance and improve seeding performance. However, these methods are unable to predict the dynamic force of tools and soil behavior because of non-li

In this study, a manually operated single row maize planter was developed and tested. Parts such as the mainframe, maize hopper, maize metering mechanism, shaft, and seed tube were designed. From the field tests, it was observed that there was a reasonable deviation of the experimented seed spacing from the designed seed spacing, this was as attributed to the speed of the human pushing the seed planter which was 0.83m/s. Also, the experimental results showed that the majority of the holes contained 2 seeds while the least contained 5 seeds. Also, from the experimental results, the seed planter

Modern agriculture demands innovation solutions to address the challenges of increasing food production while optimizing resource utilization. This research presents the design and development of a twin-row maize planter. The proposed planter incorporates a twin-row planting mechanism, departing from conventional single row systems, to maximize land usage and enhance crop productivity. Maize planted by using developed planter gives more equidistance and staggered plant spacing. This staggered spacing offer better photosynthetically active radiation.

The BARI inclined plate planter was developed for one pass tillage and seeding operation. But the planter was not capable of planting small seeds as seeds were entering between the plate and base. So, six additional MS base plates were incorporated in the planter.

I amplified a putative carotenoid ε-hydroxylase, named CYP97C19, from the yellow maize variety B73. Metabolic profiling of the carotenoid pathway in Arabidopsis lut1 mutant (lacking lutein) overexpressing maize CYP97C19 confirmed the accumulation of lutein in transgenic lines at the expense of zeinoxanthin. This allowed me to conclude that maize CY P97C19 is a functional ε-hydroxylase. In a separate experiment, I characterized two transgenic lines overexpressing the Arabidopsis Oran

Plant growth and productivity are compromised by environmental stresses such as pathogens, extreme temperatures, drought and high salinity. Being sessile organisms, plants had to develop different physiologic and biochemical strategies to cope with these potential harmful situations. Drought in particular is one of the major environmental stresses that plants are forced to endure during their life cycle. The adaptation to water deficit is controlled by a cascade of molecular networks that start with the perception of water shortage which leads to increases in the ABA levels. Even though the

Abstract:
Introduction Previous research had suggested that benzoxazinoids, a class of defensive metabolites found in maize, wheat, rye, and wild barley, are not only direct insect deterrents, but also influence other areas of plant metabolism. In particular, the benzoxazinoid 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxa- zin-3(4H)- one (DIMBOA) was implicated in: (i) altering plant growth by interfering with auxin signaling, and (ii) leading to the induction of gene expression changes and secondary plant defense responses. The overall goal of this proposal was to identify mechanisms by which benzoxazinoids i

Abstract:
The objectives of the project were to (a) compare effects ofT22 and T-203 on growth promotion and induced resistance of maize inbred line Mol7; (b) follow induced resistance of pathogenesis-related proteins through changes in gene expression with a root and foliar pathogen in the presence or absence of T22 or T-203 and (c) to follow changes in the proteome of Mol? over time in roots and leaves in the presence or absence of T22 or T-203. The research built changes in our concepts regarding the effects of Trichoderma on plants; we hypothesized that there would be major changes in the physiology

Abstract:
Maize productivity in Indonesia was still low (5.241 tons/ha) compared to the average of the ten largest maize producing countries in the world (6.179 tons/ha). The potential for maize on the island of Madura is approximately 360,000 hectares. The potential for maize cultivation in Madura continues to decrease in land quality due to improper land clearing and land-use change. The purpose of this research was to make a map of land suitability for maize using Remote Sensing Data and Geographic Information System (GIS). The land suitability method for maize plants used satellite imagery as a data

Full text
Abstract:
We have studied the regulation of the maize Ac and MuDR transposable elements activities during plant development. Ac was studied in an heterologous system (transgenic tobacco plants and cell suspensions) while MuDR was studied in the native maize background. The focus of this study was on the transcriptional regulation of Ac and MuDR. For Ac, the major achievements were to show that 1-It is autoregulated in a way that the Ac-encoded transposase can repress the activity of its own promoter; 2-It is expressed at low basal level in all the plant organs that were studied, and its activity is stro

Full text
Abstract:
The transition of plants from a juvenile to adult growth phase entails a wide range of changes in growth habit, physiological competence and composition. Strikingly, most of these changes are coordinated by the expression of a single regulator, micro RNA 156 (miR156) that coordinately regulates a family of SBP genes containing a miR156 recognition site in the coding region or in their 3’ UTR. In the framework of this research, we have taken a broad taxonomic approach to examine the role of miR156 and other genetic regulators in phase change transition and its implication to plant development a

Full text
Abstract:
The goal of this work was to understand the role of the enzyme sucrose synthase (SuSy) in synthesis of cellulose and callose in plants. The work resulting from the this grant leads to a number of conclusions. SuSy clearly plays diverse roles in carbon metabolism. It can associate with the plasma membrane of cells undergoing rapid cellulose deposition, such as cotton fibers, developing maize endosperm, gravistimulated pulvini, and transfer cells of the cotton seed. It is also concentrated at sites of high callose deposition (tapetal cells; cell plates). When SuSy levels are lowered by mutation

Full text
Abstract:
Soil microorganisms enhance the plant availability of phosphorus (P). This ability is related to the production of organic acids and the activity of phosphatases. It is assumed that the production of organic acids solubilize insoluble phosphate forms to usable form such as orthophosphate, increasing its potential availability to plants (Vázquez et al. 2000). Filamentous fungi such as Trichoderma sp. have advantages in acid soils presenting morphological and metabolic characteristics that make them promising organisms (Nahas, 1996; Vera et al, 2002).

Abstract:
Meiotic recombination contributes to the generation of biodiversity as well as to genome stability, ensuring the proper segregation of homo logs during meiosis. It is also an essential step in the process of plant breeding. It generates the diversity needed by the breeder for selection of novel varieties. In this project, we have collaborated towards the goals to identify and characterize key genes involved in meiotic recombination. In addition we have shown how some of these genes can be used, through loss of function, or through overexpression, to enhance homologous recombination in Arabidop

Abstract:
We had proposed to look at several aspects of auxin metabolism in fruit tissues: 1) IAA biosynthesis from tryptophan and IAA biosynthesis via the non-tryptophan pathway; 2) changes in the capacity to form conjugates and catabolites of auxin at different times during fruit development and; 3) the effects of modifying auxin metabolism in fruit tissues. The latter work focused primarily on the maize iaglu gene, with initial studies also using a bacterial gene for hydrolysis of IAA-aspartate. These metabolic and molecular studies were necessary to define potential benefits of auxin metabolism modi
