Effects of chemical delinting on the level of occurrence and development of Colletotrichum gossypii associated with cotton seeds The present work was conducted in two phases. The first phase evaluated how the lenght of time of chemical delinting, 1:30 and 4:30 min, effected the level of infection by Colletotrichum gossypii on artificially inoculated cotton (Gossypium hirsutum) seeds. Non-delint...

The present study was planned to enable in vitro conservation of Vanda testacea, a highly medicinal orchid species through asymbiotic seed germination technique Mitra medium supplemented with cytokinins (Kn - 4.65 μM, BAP 4.44 μM), and auxin (NAA- 5.37 μM). frequency initiation higher NAA augmented seedlings developed 12.50 ± 0.50 weeks. Coconut water (20%) proved optimum for the multiplication...

The beneficial endophytic fungus Piriformospora indica colonizes the roots of many plant species, including the model plant Arabidopsis thaliana. Its colonization promotes plant growth, development, and seed production as well as resistance to various biotic and abiotic stresses. In the present work, P. indica was tested as potential antagonist of the sedentary plant-parasitic nematode Heterode...

Three genes from the T(R) region of pTi15955 were introduced into tobacco (Nicotiana tabacum L.) to direct the synthesis of the mannityl opines from hexose sugars and glutamine or glutamate. Opines were present in all tissue types tested and accumulated to levels of 100 to 150 micrograms per milligram dry weight in root, stem, and leaf tissues. Opine-producing plants appeared normal with respec...

Endophytic bacteria have the capability of colonizing interna1 host tissues and this makes them a valuable tool to improve crop performance. By systemicaily colonising roots they have potential to develop into biological control agents of plantparasitic nematodes. This is because i) they are easy to culture in vitro; ii) can be applied as seed treatments; iii) reduce initial root damage; iv) es...

Like other plant compartments, the seed harbors a microbiome. The members of microbiome are first to colonize germinating seedling, and they may initiate trajectory assembly for next generation. Therefore, important dynamics vertical transmission potentially beneficial symbionts. However, it remains challenging assess at individual level (and, therefore, future plants) due low endophytic microb...
