Biochemical Studies on the Rice Blast Disease

open access: yesJournal of the agricultural chemical society of Japan, 1957
47菌株の稲熱病菌を用いてT. C. A-cycleに関与する有機酸塩の利用度,セルローズ利用度,ペクチナーゼの差異並びに北大農学部菌株のNo. 1及びNo. 2のビオチン生成量等の試験を行い次の如き結果を得た. (1) ビオチンを要求しないNo. 1及びNo. 2をビオチン欠合成培地で培養してビオチン生成能の有無を検した.即ち培養濾液及び洗滌菌体の酸加水分解物についてBioassayでビオチン量を試験した結果,ビオチン生成能は認められなかった.此等の菌株は糖代謝の型式が他の菌株とは異るものと考えられる. (2) 炭素源としてはコハク酸,フマール酸,クエン酸の利用度並びに此等の酸に1/100Mマロン酸を添加した培地の利用度に就て試験した結果, 9菌株に就てはT. C.

Macrocytosis in Crohn's disease: a devastating blast [PDF]

open access: yesBMJ Case Reports, 2013
A 47-year-old woman with a 36-month history of Crohn's disease with one previous bowel resection treated with azathioprine was found to have a persistently raised mean corpuscular volume (MCV) on routine complete blood count testing. Despite vitamin B12replacement, her MCV remained elevated.

Agrobacterium-Mediated Transformation of pMDC140 Plasmid Containing the Wheatwin2 Gene into the Tadong Rice Genome

open access: yesAgronomy, 2021
Blast disease resulting from Magnaporthe oryzae fungal infection reduces annual rice yield by up to 30% globally. The wheatwin2 (wwin2) is a pathogenesis-related (PR) gene that encodes for a PR-4 protein with chitinase properties that is capable of ...

Toxins in Blast-diseased Rice Plants [PDF]

open access: yesAgricultural and Biological Chemistry, 1974
The occurence of tenuazonic acid (T. A.), which had been isolated from the culture broth of blast fungus, in blast-diseased rice plants was surveyed to ascertain whether or not this substance is one of the vivotoxins. T. A. was detected in four of six samples of blast-diseased rice plants, two of which had relatively high T. A.
