Five phenolic constituents have been identified in Yucca schidigera bark, and their structures were established by spectral (FABMS and NMR) experiments. These included two known stilbenes, trans-3,4',5-trihydroxystilbene (resveratrol) and trans-3,3',5,5'-tetrahydroxy-4'-methoxystilbene, as well as three novel compounds, yuccaols A, B, and C, with spiro-structures rarely occurring in the plant kingdom. It is suggested that yuccaols A-C are biosynthethized via attachment of a stilbenic derivative to the carbocationic intermediate of the oxidative flavanone-flavonol conversion.

SHATTERPROOF 2 regulates TAA1 expression for the establishment of the gynoecium valve margins. Gynoecium development and patterning play a crucial role in determining the ultimate structure of the fruit and, thus, seed production. The MADS-box transcription factor SHATTERPROOF 2 (SHP2) contributes to valve margin differentiation and plays a major role in fruit dehiscence and seed dispersal.

Reducing greenhouse gas (GHG) emissions from livestock is a crucial step towards mitigating the impact of climate change and improving environmental sustainability in agriculture. This study aimed to evaluate the effects of Yucca schidigera extract, chitosan, and chitosan nanoparticles as feed additives on in vitro GHG emissions and fermentation profiles in ruminal fluid from bulls. Total gas, CH, CO, and HS emissions (up to 48 h), rumen fermentation profiles, and CH conversion efficiency were measured using standard protocols.

The Arabidopsis transcription factor ATAF1 negatively regulates thermomorphogenesis by inhibiting the expression of key genes involved in thermoresponsive elongation. DET1-mediated ubiquitination promotes ATAF1 degradation. In response to warmer, non-stressful average temperatures, plants have evolved an adaptive morphologic response called thermomorphogenesis to increase their fitness.
