conventional and modern plant-breeding strategies- (a) Crossbreeding of two existing varieties. A new variety can be isolated after several generations of selective breeding. (b) Random mutagenesis by irradiation or chemicals. Mutations associated with a phenotype of interest can be isolated by backcrossing and subsequent genome sequencing. (c) Genetically modified transgenic crops. A transgene from an unrelated organism can be cloned and transferred to the genome of crops. (d) Genome manipulation by CRISPR/Cas9. A crop genome can be manipulated at the single nucleotide resolution with CRISPR/Cas9 technology. This technique enables breeders to introduce multiplex mutations into the genome of any plant species #research #indianfarming #geneediting #plantbreeding #science #pyramidseeds Namdeo Umaji Agritech India Pvt Ltd

One of important characteristics in cucurbits - 1-What do the words monoecious and dioecious mean? Monoecious plants contain both male and female reproductive parts on the same plant, while dioecious plants are either male or female! 2- Why is this information important? Some dioecious plants need a member of the opposite sex nearby for pollination, for example, Pointed gourd & Ivy gourds are dioecious and (many) female Pointed gourd & Ivy gourds will not produce fruits unless there is a male nearby! Monoecious vs. dioecious Monoecious plants have male flowers and female flowers in separate structures on the same plant. Flowers can be perfect, with male and female parts in the same flower Or imperfect, with separate male and female flowers Dioecious plants have male and female flowers on different plants, so the entire plant is either male or female. #research #indianfarming #geneediting #plantbreeding #science #pyramidseeds #agriculture Namdeo Umaji Agritech India Pvt Ltd

Here's a brief comparison of eudicots with thick cotyledons, eudicots with thin cotyledons, and monocots:- Eudicots with Thick Cotyledons- 1. Cotyledons are relatively thick and fleshy. 2. Typically store nutrients for the developing plant. 3. Examples include beans, peas, and sunflowers. 4. Typically have net-veined leaves. 5. Vascular bundles in the stem arranged in a ring. Eudicots with Thin Cotyledons- 1. Cotyledons are thin and serve mainly as seed leaves. 2. Do not store significant nutrients. 3. Examples include roses, tomatoes, and oaks. 4. Often have reticulate (net-like) venation in their leaves. 5. Vascular bundles in the stem usually arranged in a ring. Monocots- 1. Have a single cotyledon (seed leaf). 2. Typically store limited nutrients in the cotyledon. 3. Examples include grasses, lilies, and orchids. 4. Usually have parallel-veined leaves. 5. Vascular bundles in the stem scattered throughout.

Life Cycle of Angiosperms: Featuring Mitosis and Meiosis 1. Seed Germination - The life cycle begins with the germination of a seed, where a diploid (2n) zygote within the seed undergoes mitosis. - Mitosis results in the formation of a multicellular sporophyte (2n) plant. 2. Vegetative Growth - The sporophyte develops roots, stems, and leaves through continued mitotic cell divisions. 3. Reproduction - Angiosperms produce flowers, which contain both male (stamen) and female (pistil) reproductive organs. - Meiosis occurs within the sporangia of the stamen and pistil, leading to the formation of haploid (n) pollen and ovules. 4. Pollination - Pollination facilitates the transfer of haploid pollen to the stigma of the pistil. 5. Fertilization - Following successful pollination, the pollen tube delivers haploid sperm to the haploid egg cell. - Fertilization results in the formation of a diploid zygote (2n). 6. Seed Development - The zygote develops into a diploid embryo (2n) within the ovule, which matures into a seed. - This part of the life cycle involves mitotic divisions. 7. Seed Dispersal - Mature seeds are dispersed through various methods. 8. Germination (again) - Under suitable conditions, the seed germinates, and the cycle restarts with mitotic divisions. Understanding the roles of both mitosis and meiosis in the life cycle of angiosperms is crucial to appreciate their complex reproductive process and diversity! #Angiosperms #Mitosis #Meiosis #PlantLifeCycle #research #indianfarming #geneediting #plantbreeding Namdeo Umaji Agritech India Pvt Ltd

Intercropping of the halophyte Arthrocaulon macrostachyum & tomato Major crop production constraints in arid and semi-arid regions are related to water and soil salinity, water shortage, and nutrient deficiencies in the soil. In addition, intensive agriculture, based on monocultures, causes extensive use of water, fertilizers, energy, and pesticides, ultimately leading to soil damage and losses of genetic biodiversity. To develop more sustainable agriculture in the context of global climate change, the development of new farming systems is a must. Halophytes are considered a valuable tool for soil phytoremediation in arid and semi-arid regions, contributing to food security and diversification. The introduction of halophytes in agriculture may help develop sustainable and profitable farming practices. The intercropping of cash crops and halophytes may constitute a valuable approach for stress mitigation in salt-affected areas since halophytes can effectively remove salts from the environment, enhancing crop production. Tomato plants increased fruit yield under soil and water salinity conditions when intercropping was established with several halophyte species. The intercropping with halophytes has also been suggested as an effective agronomic system to cope with soil and water salinity in other important crops such as cotton, watermelon, and pepper.

CRISPR and genome editing Genome editing involves using a nuclease—in this case, Cas9—to target specific sequences of DNA. The double-stranded break in the DNA created by Cas9 may be used to inactivate a gene to study its function, or to insert new sequences of nucleotides.
