Geranylgeranylated-chlorophyll-protein complexes in lhl3 mutant of the green alga Chlamydomonas reinhardtii.

Chlorophylls a and b (Chl a and b) are involved in light harvesting, photochemical reactions, and electron transfer reactions in plants and green algae. The core complexes of the photosystems (PSI and PSII) associate with Chl a, while the peripheral antenna complexes (LHCI and LHCII) bind Chls a and b. One of the final steps of Chl biosynthesis is the conversion of geranylgeranylated Chls (Chls) to phytylated Chls by geranylgeranyl reductase (GGR).

Use of X-ray irradiation for inactivation of Aspergillus in cannabis flower.

California cannabis regulations require testing for four pathogenic species of Aspergillus-A. niger, A. flavus, A.

Intragenic enhancers and suppressors of phytoene desaturase mutations in Chlamydomonas reinhardtii.

Photosynthetic organisms synthesize carotenoids for harvesting light energy, photoprotection, and maintaining the structure and function of photosynthetic membranes. A light-sensitive, phytoene-accumulating mutant, pds1-1, was isolated in Chlamydomonas reinhardtii and found to be genetically linked to the phytoene desaturase (PDS) gene. PDS catalyzes the second step in carotenoid biosynthesis--the conversion of phytoene to ζ-carotene.

Novel adenoviral vectors coding for GFP-tagged wtCFTR and deltaF508-CFTR: characterization of expression and electrophysiological properties in A549 cells.

E1/E3-deleted adenoviral vectors expressing an N-terminal green fluorescent protein (GFP) reporter gene fused to either wtCFTR (H5.040CMVEGFP-wtCFTR) or deltaF508-CFTR (H5.040CMVEGFP-deltaF508CFTR) were generated.

Rep/Cap gene amplification and high-yield production of AAV in an A549 cell line expressing Rep/Cap.

Cell lines stably expressing rep/cap are important tools for studying adeno-associated virus (AAV) biology and producing AAV vectors. Several rep/cap cell lines have been isolated, each of which is based on HeLa cells. Infection of these cell lines with adenovirus for production of AAV vector is associated with substantial amplification of the rep/cap gene.
