The ADP-glucose- or UDP-glucose-specific starch synthetase bound to sweet-potato (Ipomoea batatas) starch granules is localized in the granules, and the UDP-glucose-specific enzyme was solubulized by urea/pullulanase treatment of the starch granules.

Roundup Ready cotton varieties are widely planted on the Texas High Plains, with effective control of a wide range of annual and perennial weeds achieved with glyphosate. With the current Roundup Ready technologies, postemergence over-the-top (POST) applications must be made prior to the 5-leaf cotton growth stage. Wet or windy conditions may make it difficult to treat large acreages during thi...

Morningglories are troublesome weeds in row crops and other agricultural areas throughout the United States. Plants of pitted morningglory, sharppod morningglory, and a fertile ‘‘hybrid’’ between pitted and sharppod morningglory (hybrid morningglory), were compared with cypressvine, ivyleaf, palmleaf, purple moonflower, red, and smallflower morningglories in greenhouse studies at Stoneville, MS...

ダイズ圃場では帰化アサガオ類の蔓延が深刻であり，防除技術の確立が求められている。そこで，本研究ではマルバアメリカアサガオの防除におけるイマザモックスアンモニウム塩液剤（I液剤）のベンタゾン液剤（B液剤）との体系処理効果および，ダイズの薬害程度と収量に及ぼす影響を明らかにすることを目的とした。2017年～2019年の圃場試験の結果，マルバアメリカアサガオの残草量は，I液剤の単独処理では処理時期が遅いほど少ない傾向で，ダイズ2葉期処理の防除効果が最も高かった。また，ダイズ1葉期のI液剤と3～4葉期のB液剤の体系処理によって，残草量を土壌処理剤のみを処理した対照区と比較して87～97％抑制した。I液剤処理区のダイズ子実収量には有意な低下は認められなかった。しかし，収量低下程度は年次間で差が大きく，2019年ではI液剤を処理せずに完全除草した対照区と比較して最大で27％低下した。I液剤処理区...

Glechoma L. (Lamiaceae) is distributed in eastern Asia and Europe. Understanding chromosome evolution in Glechoma has been strongly hampered by its small chromosomes, constant karyotype and polyploidy. Here phylogenetic patterns and chromosomal variation in Glechoma species are considered, using genome sizes, chromosome mapping of 5S and 35S rDNAs by fluorescence in situ hybridisation (FISH), a...
