Fertirrigação e regulador de crescimento na produção de mudas de café em tubete [PDF]

open access: yes, 2018
The use of quality seedlings is important in establishing a productive coffee crop. However, the most widely used method to produce coffee seedlings is time consuming (6-12 months) and lacks new production technologies.

Pectin Metabolism Influences Phloem Architecture and Flowering Time in Arabidopsis Thaliana

open access: yesAdvanced Science, EarlyView.
Cell wall remodeling mediated by changes in pectic homogalacturonan, including its methyl‐esterification status and degradation, shapes wall architecture. This study finds that pectin metabolism dynamically modulates wall properties and triggers auxin responses, which influence phloem morphogenesis and function, mediating the long‐distance transport of

TaPPR13, a Pentatricopeptide Repeat Protein Gene Activated by TaBZR2, Confers Drought Stress Tolerance by Enhancing the Antioxidant Defense System and Promoting Retrograde Signaling in Wheat (Triticum aestivum)

open access: yesAdvanced Science, EarlyView.
TaPPR13, a PPR protein family gene in wheat is activated by TaBZR2 to enhance drought stress tolerance and photosynthetic capacity. It achieves this by interacting with TaAOR1 and TaSIG5 to improve antioxidant defense and regulate chloroplast gene expression. Abstract The wheat (Triticum aestivum) brassinazole‐resistant 2 (TaBZR2) gene is identified as

Demographic viability of populations of \u3cem\u3eSilene regis\u3c/em\u3e in midwestern prairies: relationships with fire management, genetic variation, geographic location, population size and isolation [PDF]

open access: yes, 1998
We studied the demographic viability of populations of a long-lived iteroparous prairie perennial, Silene regia, in relation to management regimes, population sizes, geographical region (Ohio and Indiana vs.

A Generalization of Connes-Kreimer Hopf Algebra

open access: yes, 2005
``Bonsai'' Hopf algebras, introduced here, are generalizations of Connes-Kreimer Hopf algebras, which are motivated by Feynman diagrams and renormalization. We show that we can find operad structure on the set of bonsais.

Inhibition of RNase to Attenuate Fungal‐Manipulated Rhizosphere Microbiome and Diseases

open access: yesAdvanced Science, EarlyView.
Fusarium graminearum uses its virulence effector Fg12, a fungal RNase, to manipulate the host rhizosphere microbiome and promote infection. Guanosine monophosphate (GMP) blocks Fg12's RNase activity. This reveals a key pathogen‐microbiota interaction mechanism and proposes GMP as a targeted strategy to disarm this core fungal effector, offering a ...

Living Close to Your Neighbors: The Importance of Both Competition and Facilitation in Plant Communities [PDF]

open access: yes, 2014
Recent work has demonstrated that competition and facilitation likely operate jointly in plant communities, but teasing out the relative role of each has proven difficult.

PRC1‐Mediated H2Aub Loop Formation and Function in Arabidopsis

open access: yesAdvanced Science, EarlyView.
In the Arabidopsis genome, H2Aub and H3K27me3 marks do not always co‐localize, and some regions are marked exclusively by H2Aub. By using Capture‐Hi‐C, it is found that H2Aub loops are preferentially established between two H2Aub enriched regions.

Co‐Selection of Low Cadmium Accumulation and High Yield During Tomato Improvement

open access: yesAdvanced Science, EarlyView.
This study finds that large‐fruited tomatoes accumulate less cadmium (Cd) compared to wild tomatoes and cherry tomatoes. This is because, during the improvement process of tomato, the low‐Cd allele LCT1A and the large fruit allele fw3.2T are closely linked, leading to a co‐selection event.
