Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1
The FEBS Journal, EarlyView.In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

The FEBS Journal, EarlyView.Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Journal of Integrative Plant Biology, EarlyView.Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

Urtica circularis: una planta medicinal Argentina
, 2018 The nettle has been used since ancient times as a medicinal plant. Urtica dioica (Urticaceae) is widely distributed around the world and its popular uses have been intensively studied. Urtica circularis (Hicken) Sorarú is an Argentinean native herb that shares its common name, genus, and some of the ethnomedical uses.

Journal of Integrative Plant Biology, EarlyView.The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Ocorrência de quimiotipos em Talauma ovata, uma planta medicinal brasileira
Revista Brasileira de Plantas Medicinais, 2005 Talauma ovata St. Hil. (Magnoliaceae) is a big tree, which the trunk bark has been used in folk medicine against fever. Chemical analysis of nine populations showed the occurrence of two chemotypes in well-defined geographic localization. The first chemotype is characterized by neolignans and is found in latitude bellow 20°S.

Journal of Integrative Plant Biology, EarlyView.Engineered the plant‐colonizing yeast Yarrowia lipolytica to produce and deliver double‐stranded RNAs targeting key genes of the gray mold fungus Botrytis cinerea produced a ‘living factory’ that continuously synthesizes and releases gene‐silencing molecules on plant surfaces, effectively suppressing the pathogen.

Spatially Resolved ABA Signalling Reveals Dual Role in Tomato Yield
Plant Biotechnology Journal, EarlyView.ABSTRACT Abscisic acid (ABA) is a central hormonal regulator of plant adaptation to stress and developmental progression. However, its contribution to agronomic traits such as yield remains unclear due to the pleiotropic nature of ABA signalling. To disentangle distinct physiological functions of ABA, we employed a receptor‐specific gain‐of‐function ...

More Science Than Art: The First Botanical Garden in Portugal (c. 1650)
Renaissance Studies, EarlyView.ABSTRACT Gabriel Grisley, a German physician, came to Portugal and founded a garden near the Xabregas River in Lisbon, during the 1610s under the Spanish kings' rule. In view of the utility a botanic garden represented for the kingdom, he was able to obtain a royal privilege from King João IV during the Restauration War against the Spanish (1640–1668).
