Regulation of Sporangia Development in Phytophthora infestans [PDF]
, 2020 Phytophthora infestans causes the late blight disease of potato and tomato. Spores of Phytophthora are important for dissemination and causing infection. In this thesis, I studied several aspects of Phytophthora spore biology.

Myb transcription factors and light regulate sporulation in the oomycete Phytophthora infestans.
PLoS ONE, 2014 Life cycle progression in eukaryotic microbes is often influenced by environment. In the oomycete Phytophthora infestans, which causes late blight on potato and tomato, sporangia have been reported to form mostly at night. By growing P.

Nordic Journal of Botany, Volume 2026, Issue 10, October 2026.Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

The role of sporangia in the epidemiology of pearl millet downy mildew [PDF]
, 1980 Exposure of field plants to sporangial inoculum provided by earlier planted "infector rows" resulted in considerably more downy mildew on all Pennisetum americanum cvs. tested than was obtained by exposure of the cvs.

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
New Phytologist, Volume 252, Issue 1, Page 54-68, October 2026.Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

The genus Arthrocardia (Corallinales, Rhodophyta) in New Zealand: Description of three new species
Phycological Research, Volume 74, Issue 4, Page 333-342, October 2026.SUMMARY Three new species of the coralline algal genus Arthrocardia (Corallinophycidae, Rhodophyta) are described from New Zealand: A. meridionalis, A. perplexa, and A. robusta. These species are difficult to distinguish based on morphoanatomical characters alone and require molecular sequence data for reliable identification.

Temperature and Light Effects on Germination of Peronospora effusa Sporangia
, 2017 Spinach downy mildew, caused by the biotrophic oomycete Peronospora effusa, is an economically important disease that is found in all spinach growing regions of the US. To effectively predict disease risk we need to understand the response of P.

THERMAL VARIATION FOR GROWTH OF ZOOSPORES OF Albugo spp.
Revista de Agricultura Neotropical, 2018 The objective of this work was to identify the time of the thermal shock that promotes the greater release of zoospores/sporangia. The experiments were carried out with five treatments, varying the thermal variation time (20', 30', 40', 50' and 60') of ...
