Molecular Analysis of the Differential Activity of Sox8 and Sox10 in Oligodendroglial Cells.

Oligodendroglial cells generate myelin sheaths in the vertebrate central nervous system to render rapid saltatory conduction possible and express the highly related Sox8, Sox9 and Sox10 transcription factors. While Sox9 and Sox10 fulfill crucial regulatory roles, Sox8 has only a limited impact on oligodendroglial development and myelination. By replacing Sox10 with Sox8 or Sox9 in the oligodendroglial Oln93 cell line, and comparing the expression profiles, we show here that Sox8 regulates the same processes as Sox10 and Sox9, but exhibits a substantially lower transcriptional activity under standard culture conditions.

Cytochrome P450s of the CYP79 family catalyze two N-hydroxylation reactions, converting a selected number of amino acids into the corresponding oximes. The sorghum genome (Sorghum bicolor) harbours nine CYP79A encoding genes, and here sequence comparisons of the CYP79As along with their substrate recognition sites (SRSs) are provided. The substrate specificity of previously uncharacterized CYP79As was investigated by transient expression in Nicotiana benthamiana and subsequent transformation of the oximes formed into the corresponding stable oxime glucosides catalyzed by endogenous UDPG-glucosyltransferases (UGTs).

Dense planting of single-cross hybrids contributes to maize yield increase over the past decades. Leaf angle, an important agronomic trait relevant to planting density, plays a fundamental role in light penetration into the canopy and photosynthetic efficiency. Leaf angle is a key parameter of plant architecture in the concept of smart canopy.

Chatan & Promprom, a new species from the Zingiberaceae family, is described from Sakon Nakhon Province in northeastern Thailand. This species was identified during field expeditions conducted between 2018 and 2024 in Phu Pha Yol National Park. The morphological characteristics of , such as red or pinkish-red leaf sheaths, leaf blades (1.

Various members of the viral genera Furovirus and Bymovirus are damaging pathogens of a range of crop species. Infection of the soil-borne plasmodiophorid Polymyxa graminis transmits both Japanese soil-borne wheat mosaic virus (JSBWMV) and the barley yellow mosaic virus (BaYMV) to barley, but their interaction during an episode of their co-infection has not been characterized to date. Here, we present an analysis of the titer of JSBWMV and BaYMV in plants of winter barley growing over a five-month period from late fall until mid-spring.
