Investigation Of The Regulation Mechanism Of Arabidopsis Thaliana Anion Channel Slah2, Fen-Yong Yao, Guo-Ning Qi, Jamshaid Husssain
Investigation Of The Regulation Mechanism Of Arabidopsis Thaliana Anion Channel Slah2, Fen-Yong Yao, Guo-Ning Qi, Jamshaid Husssain
Turkish Journal of Botany
In recent years a slow-type anion channel (SLAC) family composing five members, including slow anion channel associated 1 (SLAC1) and four SLAC1 homologs (SLAHs), has been identified in Arabidopsis thaliana. The anion channels are activated by calcium-dependent protein kinases (CPKs) and play crucial roles in mediating anion fluxes across plasma membranes. SLAH2 is specifically expressed in root stele cells and has been characterized as a nitrate-selective anion channel activated by CPK21 and CBL-interacting protein kinase 23 (CIPK23). However, the interaction between CPKs and SLAH2 and how it is regulated remains to be elucidated. In this study we found that SLAH2 …

Analysis of the T1 generation revealed that both the hpt and Xa21 genes were successfully transmitted from the primary transformants to the progeny. Bioassays with two local isolates of bacterial leaf blight pathogen, Xanthomonas oryzae pv. oryzae (Xoo), showed that 14 transgenic lines were …
Relationships Between Sorghum Bicolor (Poaceae) And Its Closerelatives Based On Genomic In Situ Hybridization Evidence, Qing Liu, H L, Jun Wen
Relationships Between Sorghum Bicolor (Poaceae) And Its Closerelatives Based On Genomic In Situ Hybridization Evidence, Qing Liu, H L, Jun Wen
Turkish Journal of Botany
Sorghum bicolor (L.) Moench (sorghum) is a naturally well-established diploid species with 2n = 2x = 20. Here we provide evidence to identify the genomic relationships of S. bicolor and its extant relatives using genomic in situ hybridization. The genomic divergences between S. bicolor and its close relatives may be presented as: S. bicolor-S. x drummondii (Nees ex Steud.) Millsp. & Chase < S. bicolor-S. x almum Parodi < S. bicolor S. arundinaceum (Desv.) Stapf < S. bicolor-S. propinquum (Kunth) Hitchc. Sorghum arundinaceum probe signals showed spotted or painted patterns on the S. bicolor chromosomes, indicating that the degree of genomic divergence between S. bicolor and S. arundinaceum is distinct. It is reasonable to infer that S. bicolor might have diverged from S. arundinaceum in the early diversification history of the subgenus. The probe signal intensity of S. arundinaceum and S. propinquum is greater on the 17 chromosomes than on the remaining 23 chromosomes of S. halepense (L.) Pers., whereas S. bicolor and S. propinquum probes produced spotted or patchy signals on the 40 S. halepense chromosomes. Therefore, the degree of genomic divergence may be presented as: S. halepense-S. bicolor < S. halepense-S. arundinaceum < S. halepense-S. propinquum.
