Quiescent cottonseeds stored in a dry, anaerobic situation for over a year have been shown to contain cells whose contents are ultrastructurally similar to those of normal, fully hydrated plant cells. Plastids, mitochondria, and nuclei of the cells of cotyledon tissue in dry seeds possess normal-looking double membranes even under conditions of extreme desiccation. Previous reports have indicat...

nineteen lymph node biopsies, 3 curetting, 15 blood samples obtained from patients with lymphadenitis and high titers of toxoplasma antibodies, and 27 tonsillar tissues removed from patients because of chronic tonsillitis were inoculated intraperitoneally into mice for isolation of toxoplasma gondii. toxoplasms were isolated from 5 lymph node biopsies, one curettage material, 2 tonsillar tissue...

schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

Cotyledonary nodes taken alongwith shoot apex from seedlings of cotton (G. hirsutum) proliferated into shoots on nutrient agar medium supplemented with cytokinins. In the presence of optimal plant growth regulators, low light intensity enhanced the number of shoots initiated per explant in cotton. An average of 33.5 +/- 2.9 shoots were obtained from a single explant cultured for 8 weeks which i...

Basipetal auxin transport in 6-day-old dark-grown corn coleoptiles was severely inhibited by increasing levels of glyphosate applied during the transport period.The velocity of basipetal transport of [(14)C]indoleacetic acid in hypocotyls from 7-day-old cotton seedlings was significantly reduced when sublethal doses of glyphosate [N-(phosphonomethyl)glycine] were applied to the cotyledonary lea...

A reexamination has been made for the supposed regulation of pea (Pisum sativum cv Alaska) cotyledonary diamine oxidase (EC 1.4.3.6) activity by the embryonic axis. When dry cotyledons from which the embryo and testa have been removed surgically are imbibed by soaking in water, there is little increase of the enzyme activity during subsequent incubation on filter paper. However, if the dry coty...
