Engineering Biomimetic Sporangia in Land Plants [PDF]

open access: yesBioengineering
The land plant sporangium is unique in its ability to initiate differentiation of the reproductive germ line, leading directly to meiosis and the formation of eggs and sperm; but our lack of understanding of the processes underlying gametogenesis in ...

RT-qPCR-Based Estimation of Phytophthora infestans Sporangia Using the MFS Transporter Gene PITG_13011 [PDF]

open access: yesJournal of Fungi
Phytophthora infestans is the causal agent of late blight, one of the most destructive diseases of potato and tomato worldwide. Although qPCR-based methods are widely used to estimate pathogen biomass in infected tissues, methods for specifically ...

Involvement of two putative gene clusters for exopolysaccharide biosynthesis and modification in sporangium formation in Actinoplanes missouriensis [PDF]

open access: yesApplied and Environmental Microbiology
The terminal sporangium of the actinomycete Actinoplanes missouriensis contains a few hundred spores surrounded by a matrix substance, which is mainly composed of a polysaccharide synthesized by the imp gene cluster.

Components of the Clp complex are required for sporangium formation and dehiscence in Actinoplanes missouriensis [PDF]

open access: yesJournal of Bacteriology
The actinomycete Actinoplanes missouriensis forms terminal sporangia that contain a few hundred spores. When immersed in water, the sporangium opens to release spores, which start swimming using flagella, via a process referred to as sporangium ...

Two glycoside hydrolases decompose the sporangium matrix to release spores during sporangium dehiscence in Actinoplanes missouriensis [PDF]

open access: yesmBio
The actinomycete Actinoplanes missouriensis grows as a substrate mycelium and forms terminal sporangia containing a few hundred spores surrounded by an unidentified matrix called the sporangium matrix.
