Global Conference on
“Technological Challenges and Human Resources for Climate Smart Horticulture”
Horticulture is one of the important sectors of agriculture whichconsists of fruits, flowers, vegetables, spices & condiments,plantation crops, medicinal and aromatic plants. The importanceof horticultural crops is widely acknowledged in many aspects ofinnovation, production, quality maintenance, for upliftingeconomic condition of farmers, entrepreneurs and in providingnutritional security to the people.
With the increasing fast growth of population, improvingeconomic condition and awareness of importance of fruits,vegetables and flowers, demand for horticultural products isgradually increasing. To meet the demand of horticulture productgenomic technologies can be used effectively in horticultural cropimprovement programmes. Improvement in horticulture crop isalso required to sustain in the climate change condition and makethe Climate Smart Horticulture crop.
Bioinformatics is a combination of computer,mathematics algorithm and statistics with concept inlife science to solve biological problem. The maintask of bioinformatics is to manage and analyse thebiological data. Bioinformatics has a number ofapplications in plant biology. Computational tools arevery much helpful in identification of ergonomicallyimportant gene by comparative analysis between cropplant and model species.
Bioinformatics is a tool that is used to analyse theBiological data. We can compare Bioinformatics withStatistics. As statistics is a tool to analyse data bydifferent formula and derive certain conclusions. (wecan use either our own data or data generated byothers)
Data Mining (someone’s data is now mine)

CROP IMPROVEMENT
Omics-based research and application development provide crucialresources to promote research in model and applied plant species. Acombinatorial approach using multiple omics platforms and integrationof their outcomes is now an effective strategy for clarifying molecularsystems integral to improving plant productivity.
Promotion of comparative genomics among model and applied plantsallows us to grasp the biological properties of each species and toaccelerate gene discovery and functional analyses of genes.
Bioinformatics platforms and their associated databases are alsoessential for the effective design of approaches making the best use ofgenomic resources, including resource integration.
Species-specific nucleotide sequence collections provide opportunitiesto identify the genomic aspects of phenotypic characters based ongenome-wide comparative analyses and knowledge of model organisms.
Status of genome sequencing projects in horticultural crops.
PLANT BREEDING
Plant genomics helps in understanding the genetic and molecularbasis of all biological process which helps in developing newcultivars with improved quality and reduced economic andenvironmental cost.
Now-a-days the Genome program is an important tool for the plantimprovement. This genome programme helps in identifying the keygenes and their function. This genome project generates data,which includes sequence information, markers etc. These data arethen distributed to the multinational research community.
The bioinformatics tools helps in the submission of all data throughENTREZ Global Query Cross-Database Search System to thepublic domain. This helps in retrieving sequence from the NCBI.The bioinformatics tools helps in providing rational annotation ofgenes, proteins and phenotypes.
Interspecific and intergeneric hybridization is an important researchapproach creating usable variability for breeding. Desirable traitslike resistance against pathogens or abiotic stress within varyingenvironments, composition of metabolites or morphological traitsand their responsible genes are often found only within wild species,related species and genera of the cultivars.It is possible to use theexisting variability of the primary and secondary gene pool byinterspecific and intergeneric hybridization.
Interspecific and intergeneric hybridization can be carried out both-way, generatively by crossing or somatically by protoplast fusion. TheInstitute for Breeding Research on Horticultural Crops has acquiredwide experience in the development and adaption of the generative aswell as somatic hybridization of vegetables, ornamentals and medicaland aromatic plants for many years. Both methods are very labour-intensive, long-lasting and fraught with risk. Therefore, the breedinglines are chosen very carefully and are proved for defined valuabletraits in advance.

IMPROVE NUTRITIONAL QUALITY
There are various ways of improving nutrition quality. It canbe improved by the redirection of the cellular activity, by themodification of the enzymatic transport and by regulating thefunction of the cell.
Various tools are available to identify the genes. With theadvances in the proteomics and glycomics, there are varioustools for the analysis of primary and secondary metabolicpathways.
The current advancement in plant biology research encompassing:generation of huge amount of molecular-genetic data, developmentof impressive methodological skills in molecular biologyexperimentation, and systems analyses, has set the stage to searchfor ways/means to utilize the available resources to strengtheninterdisciplinary efforts to find solutions to the challenging goals ofplant breeding efforts (such as abiotic stress tolerance) ultimatelyleading to gainful applications in crop improvement.
A positive fall out of such a realization and efforts has been theidentification/development of a new class of very useful DNA markerscalled genic molecular markers (GMMs) utilizing the ever-increasingarchives of gene sequence information being accumulated under the ESTsequencing projects on a large number of plant species in the recent years.These markers being part of the cDNA/EST-sequences, are expected torepresent the functional component of the genome i.e., gene(s), in contrastto all other random DNAbased markers (RDMs) that aredeveloped/generated from the anonymous genomic DNAsequences/domains irrespective of their genic content/information.

DEVELOPMENT OF STRESS TOLERANT VARIETIES
Stress tolerant varieties can be developed by identifyingthe Stress tolerance genes and alleles. Various tools havebeen developed to study the physiology, expressionprofiling, comparative genomics.
The KEGG database contains all the metabolic pathwayslike the pathway for the carbohydrate production. Genesin the ABA production pathway are important for thedevelopment of drought resistant varieties.
KEGG databases can be important in identifying thepathway for carbohydrate production and ABAproduction. After the identification of the pathway thegenes involved in the same pathway are studied for thedevelopment.

(B)Changes of gene expression levelsand metabolite contents of thecarotenoid biosynthesis pathway inIL3-2 compared with M82.Genes/metabolites with greenbackground are down-regulated inIL3-2, those with yellow backgroundare not changed, and those with graybackground are not measured.
The ultimate goal of bioinformatics is to integrate large-scale datafor understanding the molecular mechanism involved in variousdevelopmental processes. This understanding can help in producingthe Climate Smart Horticulture Crops.
The explosion of genomic data along with other omics data has puta great responsibility on the bioinformatics community to aid in themanagement and analyses of such data. There is a need to not onlyanalyze but also to integrate these data with functional informationand a priori knowledge. The development of efficient and powerfulin silico integrative analysis techniques can allow for higher levelsof discovery and knowledge for producing the Climate SmartHorticulture Crops.
