Multi-panel diagram describing (1) panicle number per unit area/plant architecture, (2) grain number per panicle, and (3) grain weight. Together, they summarize recent advances in understanding the crosstalk between brassinosteroids and other phytohormones in agronomic traits essential for crop improvement, such as those related to crop productivity and stress tolerance.

This new #plant #science will leave you speechless!👄
In their new #JIPB paper, Park et al. reveal that #brassinosteroid signaling has a dual #regulatory role in controlling #stomatal #development in #Arabidopsis hypocotyls🌱

Flow diagrams and micrographs illustrate that low-to-moderate brassinosteroid concentrations promote stomatal formation in Arabidopsis hypocotyls via upregulation of SPEECHLESS, and independently of BRASSINOSTEROID INSENSITIVE2 (BIN2). High brassinosteroid concentrations or direct BIN2 inhibition suppress stomatal development. BIN2 promotes stomatal formation by inactivating BRASSINAZOLE-RESISTANT1, revealing distinct regulatory pathways between hypocotyls and cotyledons.

Cytoplasmic male sterile lines are crucial for #heterosis in #crop #plants. Using an integrative approach, Guo et al. identify a #flower bud-specific lncRNA that regulates male sterility in upland #cotton. https://doi.org/10.1111/jipb.13802

Diagrams comparing mechanisms that lead to fertile vs male-sterile cotton lines. In the fertile cotton line 2074B, the long non-coding RNA lncRNA67 acted as an endogenous target mimic, regulating microRNA-mediated cleavage of GhCYP724B, encoding a cytochrome P450 that promotes brassinosteroid biosynthesis. In the cytoplasmic male sterile line 2074A, GhCYP724B interacted with a unique chimeric open reading frame, resulting in male sterility.

Imaging and gels illustrate that overexpression of the BR biosynthesis gene DWARF (DWF) or the key BR signaling gene BRASSINAZOLE-RESISTANT1 (BZR1) increases ABA levels in response to chilling stress via positively regulating the expression of the ABA biosynthesis gene 9-CIS-EPOXYCAROTENOID DIOXYGENASE1 (NCED1). BR-induced chilling tolerance was mostly dependent on ABA.

This cover highlights the article NALCN-mediated sodium influx confers metastatic prostate cancer cell invasiveness by Antoine Folcher, Dmitri Gordienko, Oksana Iamshanova, Natalia Prevarskaya and colleagues. Sustained Na+ influx via the sodium leak channel (NALCN) in aggressive prostate cancer cells recruits plasma membrane and mitochondrial Na+/Ca2+ exchangers, Ca2+ pumps and Ca2+-permeable ion channels to generate long-lasting Ca2+ oscillations. These, in turn, condition Src-regulated actin remodeling, Ca2+-dependent secretion of proteolytic enzymes and invadopodia formation, thus increasing cancer cell invasiveness.
