Introduction

Seed pathology has been recognized as its own specialization for a relatively brief time, and the term “Seed Pathology” was first coined by Mary Noble in the 1940 (Agarwal and Sinclair, 1997). Seed pathology is an essential part of seed technology as well as a sub discipline of plant pathology. According toAgarwal and Sinclair (1997), it may be defined as the study of seed borne disease and pathogens carried with seed. It also includes studies on the mechanisms of seed infection, seed transmission, the role of seed borne inoculum in disease development, methods for the detection of seed borne pathogens and non-pathogens, seed certification standards, mycotoxins and mycotoxicoses, and various methods for control of seed borne disease. Seed pathology includes the study of diseases and deterioration caused by bacteria, fungi, nematodes, viroids, viruses, physiological and mechanical disorders.

Neergaard Paul is considered the father of seed pathology. He was one of the founding father and later served as Director of the Danish Government Institute of Seed Pathology for Developing Countries, Copenhagen, Denmark, from 1956 to 1974. He served as the Chairman of the Plant Disease Committee of the International Seed testing Association (ISTA). During his tenure as Chair of ISTA, he helped standardize methods for the detection of seed borne fungi.Neergaard (1977) authored a two-volume text entitled “A Seed Pathology”. This text has served as a reference and teaching standard for the science of seed pathology throughout the world (Agarwal and Sinclair, 1997). This text focused on a wide variety of seed pathology issues, ranging from the economic significance of seed borne diseases to the assessment of seed borne inoculum.

Abstract

Vitamin C is one of the most important phytochemicals and can be found in almost all fruits and vegetables. Since it covers almost all eventualities, being water solute and prone to leaching from cells, thermally labile (one of the most labile vitamins), pH-, metal ion-, light-sensitive, as well as readily oxidizable by ascorbic acid oxidase, vitamin C is selected as the most frequently measured nutrient to evaluate the nutrients loss during thermal processing. It is generally accepted that if vitamin C is well preserved, the other nutrients are also well retained. Higher retention of vitamin C in processed products is highly desired. Herein this chapter reviews the degradation mechanism and kinetics of vitamin C of fruits and vegetables during thermal processing, such as blanching, drying, cooking and frying. It starts with an overview of the functions of vitamin C in human’s health. Then the current status for understanding of the degradation kinetics of vitamin C during thermal processing was outlined, followed by the discussion of its degradation mechanism. At last, potential strategies or alternatives to keep vitamin C are identified and discussed.

Introduction

Thar Desert is unique both from floristic and climatic parameters. Biodiversity in this region survives on a very/ fragile ecosysytem under a highly hostile environment. Major area consists of dry undulating mass of loose sand, thus, leading to shifting sand dunes. The sandy plain is full of sand-hills with serve as low depressions where salt and soda are deposited after drying. The whole area is inhospitable and sterile. Trees are rather a few and far between (Bhandari, 2005).

The Thar Desert of western India is known for its rich and ancient culture system and traditions. The communities have long been part of the Thar Desert ecosystem and have evolved specific strategies to live in harmony with its hostile environment. Orans have remained mainstay in balancing this arid ecosystem. Man of this region has never been greedy as he is today. Orans were repositories of ancient system of gene pool conservation. But, there are unregulated encroachment on the marginal lands and over-exploitation of groundwater resources. Orans has been part and parcel of the lifestyle of the Thar Desert inhabitants. Orans are used to provide vital grazing land for livestock, water, minor forest produce, medicinal plants and green cover for the villages. They were worshipped as devbhumi. Orans preserve the endemic, endangered or threatened species, medicinal plants and wild variety of cultivars found.

Lignieres and Spitz first isolated Actinobacillus from the cattle with actinomycosis like condition in Argentina in 1902. The findings were also confirmed by Nocard in 1902. Later the isolated bacterium from the cattle was named as Actinobacillus lignieresii in memory of Lignieres.

Pfeiffer (1892) first isolated Haemophilus influenzae as a cause of human influenza and it is also known as ‘Pfeiffer’s bacillus’. Other workers isolated and described different species of the genus Haemophilus from animals and birds. In 1903, Friedberger, a research assistant of Pfeiffer, isolated similar kind of bacteria from prepuce of dogs which was described later as Haemophilus canis. In 1925, Mitchell isolated Haemophilus ovis from the respiratory tract of sheep. Lewis and Shope (1931) isolated and illustrated Haemophilus suis from the infected pigs. Glasser found the association between fibrinous serositis, polyarthritis in pigs (Glasser’s disease) and a small gram-negative rod as early as 1910, later became known as Haemophilus parasuis. The bacteria was first isolated by Hjarre and Wramby in 1943. De Blieck (1931) isolated a hemophilic bacterium from the birds suffering with ‘infectious coryza’ and named the bacteria as Bacillus haemoglobinophilus coryzae gallinarum. Later it became known as Haemophilus paragallinarum (Avibacterium paragallinarum).

Cohn (1875) first observed and described a branching filamentous microorganism in the ‘concretions’ (coagulated mass) taken from a lacrimal canal, later identified as Actinomyces israelii. Bollinger first reported the yellow granules in jaw tissues of the cattle in 1877 and established the significance of the bacteria as the etiological agent. In 1878, Israel described the first human case. In 1879, Hartz observed the microscopic appearance of granules of Actinomyces and suggested the name Actinomyces bovis. Mosselman & Lihnaux (1890) and Wolf & Israel (1891) first isolated the bacteria in artificial laboratory media from lumpy jaw cases of cattle and human actinomycosis, respectively.

Limitations of Bacteria

• Normally genetically engineered bacteria are very useful for the large scale production of valuable eukaryotic proteins.
• Bacteria grow rapidly, They grow on relatively simple media, they are easy to handle, they are easily transformed, they can grow on wide range of substrates, they multiply, fast, they contain simple and well characterized genome, they can be easily modified but even though, they have their own problems…

1. Bacteria do not have intrudes and so they do not have any system or machinery to remove introns.
2. Many eukaryotic proteins undergo different types of modifications after they are produced. These modifications are known as “post translation al modifications”.
3. Each bacterial cell usually contains many copies of the plasmid but there is no mechanism to ensure the equal distribution of plasmids in daughter cells.

6.1 Introduction

This chapter presents the impact evaluation (summative) of the vegetable IPM programme that was conducted by the Central Integrated Pest Management Centre (CIPMC) Jammu in the sub-tropical areas of Jammu, Samba and Kathua districts. These districts were selected purposively as the maximum numbers of IPM-FFS were conducted by CIPMC in these three districts. Ex-post facto research design (with/without) was employed for conducting the impact evaluation of vegetable IPM-FFS programmes conducted between 2003-04 and 2007-08. This design uses a pre-existing situation as the treatment instead of actual manipulation of the variables. An ex post facto study uses a comparable site as the control to find the programme effects.

An Ex-post facto research is a systematic empirical inquiry in which the scientist does not have direct control of independent variables because their manifestations have already occurred or because they are inherently not manipulated. Inferences about relations among variables are made, without direct intervention, from co commitment variation of independent and dependent variables. This kind of research is based on a scientific and analytical examination of dependent and independent variables. Independent variables are studied in retrospect for seeking possible and plausible relations and the likely effects that the changes in independent variables produce on a single or a set of dependent variables. The ex-post facto design was also used by Peshin and Kalra (1998); Reddy (2006); Maraddi et al., (2007) while evaluating the IPM programmes. The indicators for evaluation of the IPM-FFS programme were selected based on the requirements of the research design.

1. Introduction

Antioxidants are defined as molecules which can be safely interact with free radicals and terminate the chain reaction before vital molecules are damaged (Nidhi and Gaurav, 2012). Naturally occurring antioxidants to replace synthetic antioxidants which are being restricted due to their carcinogenicity (Abdel Hameed, 2009). The antioxidant phytochemicals such as polyphenols, flavanoids and related compounds found in medicinal plants have received increasing attention for their potential role in prevention of human diseases (Upadhyay et al., 2010).
 
The genus Ophiorrhiza belongs to the family Rubiaceae and consists of about 150 species and distributed in tropical and subtropical Asia. Species of Ophiorrhiza are economically important and many of these species contain a high value anticancerous compound, a cytotoxic alkaloid camptothecin and other valuable alkaloids. Ophiorrhiza pectinata Arn. is a herbaceous plant and is distributed over peninsular India and Srilanka. A preliminary study conducted in O. pectinata also contains this important alkaloid (0.0040mg/g dry wt). Leaves and stem contain traces of hydrocyanic acid. The main objective of the present study is to evaluate the antioxidant and radical scavenging property of the chloroform methanol and water extract of whole plant of O. pectinata.
