A hipótese de que a domesticação de culturas propagadas clonalmente, como o abacaxi da América do Sul, era uma "operação de uma etapa". Sequenciamos o genoma de Ananas comosus var. bracteatus CB5 e reuniu 513 Mb em 25 cromossomos com 29.412 genes. A comparação dos genomas de CB5, F153 e MD2 elucidou a base genômica da produção de fibras, formação de cores, acúmulo de açúcar e maturação dos frutos. Também ressequenciamos 89 genomas de ananás . Os cultivares 'Smooth Cayenne' e 'Queen' exibiram mistura antiga e recente, enquanto o 'Singapore Spanish' apoiou uma operação de domesticação em uma etapa. Identificamos 25 varreduras seletivas, incluindo uma varredura forte contendo um par de inibidores de bromelina duplicados em conjunto. Quatro genes candidatos à auto-incompatibilidade foram ligados no F153, mas não eram funcionais no CB5 auto-compatível. Nossas descobertas apóiam a coexistência de recombinação sexual e uma operação em uma etapa na domesticação de culturas propagadas por clones. Este trabalho orienta a exploração de trajetórias de domesticação sexual e assexuada em outras culturas propagadas por clones.
A maioria das culturas de grãos, vegetais e plantas ornamentais é produzida sexualmente através da propagação de sementes, enquanto a maioria das árvores frutíferas, tubérculos e algumas plantas ornamentais são clonais propagadas através de enxertos, cultura de tecidos, divisões ou estacas. As espécies que se reproduzem sexualmente passam por centenas a milhares de gerações de recombinação durante a domesticação; essa seleção recorrente deixa assinaturas altamente tratáveis no genoma. Por outro lado, a domesticação de culturas propagadas clonicamente depende da reprodução vegetativa e sexual, agindo esporadicamente nos clones de vida longa. Pode até ser uma operação de uma etapa, em que a seleção é concluída depois que um clone é selecionado 1 . Portanto, as culturas clonais podem ter passado de zero a alguns ciclos de recombinação e seleção pós-domesticação, em nítido contraste com as culturas anuais reproduzidas sexualmente. O abacaxi ( Ananas comosus (L.) Merr.) É uma cultura de frutas originada e domesticada na América do Sul. Segundo Bertoni 2 , o nome do gênero Ananas significa 'excelente fruto' na língua guarani do Paraguai. O abacaxi foi domesticado> 6.000 anos atrás, com restos arqueobotânicos datados de 3.500 anos atrás na América do Sul e distribuídos para a Mesoamérica> 2.500 anos atrás 3 , 4 , 5 . O abacaxi é propagado clonalmente usando a coroa de frutas folhosas, enxertos ou ventosas. O abacaxi vermelho ( Ananas comosus var. Bracteatus ) era

Scientists have a growing interest in the design of soft robots that are safer and more nimble than their rigid counterparts.
One area in which they’ve been challenged in the development of these robots is at the smaller scale, such as in the millimeter range, because of the complexity of fabricating such fine parts at this size.
|Researchers in China and Singapore have combined efforts to develop a generic process flow to guide the 3D printing of miniature soft pneumatic actuators that are smaller than a coin. Researchers also designed a soft debris remover with an integrated miniature to help navigate through a confined space or collect small objects in hard-to-reach positions.

Now a team of researchers from Singapore and China have combined efforts to develop a 3D-printing process using digital light projection (DLP) to develop pneumatic actuators for soft robots ranging in size from 2 millimeters to 15 millimeters, with a feature size of 150-350 micrometers, they said.
The method paves the way for easier fabrication of tiny soft robots well-suited for navigation in confined areas as well as the manipulation of small objects, researchers said. These robots could find use in various applications, from medical technology to jet maintenance.
Specifically, the scientists--from the Singapore University of Technology and Design (SUTD), Southern University of Science and Technology (SUSTech), and Zhejiang University (ZJU)—have presented a generic process flow for guiding DLP 3D printing of these miniature pneumatic actuators.
The method offers an alternative to the molding and soft-lithography methods that are typically used and require great delicacy, thus are more complex, said Associate Professor Qi (Kevin) Ge from SUSTech, the lead researcher of the research project.
"To ensure reliable printing fidelity and mechanical performance in the printed products, we introduced a new paradigm for systematic and efficient tailoring of the material formulation and key processing parameters,” he said in a press statement.
DLP 3D printing is a process in which photo-absorbers are commonly added into polymer solutions to enhance printing resolutions in both horizontal and vertical directions. However, if the dose of those absorbers is too high, it can lead to rapid degradation in the material's elasticity, an aspect that’s critical for soft robots to sustain large deformations, researchers said.
To achieve their results and not sacrifice any durability in potential soft robots fabricated using the process, researchers made a number of informed decisions, said Yuan-Fang Zhang, a researchers from SUTD who worked on the project.
First the team selected a photo-absorber with good absorbance at the wavelength of the projected UV light and then conducted mechanical performance tests to determine the appropriate material formulation, he said.
“Next, we characterized the curing depth and XY fidelity to identify the suitable combination of exposure time and sliced layer thickness," Zhang said in a press statement.
This process flow enabled researchers to develop a multimaterial 3D-printing system to fabricate a variety of miniature and structurally diverse soft pneumatic robotic actuators, researchers said.
Moreover, the method should be compatible with commercial stereolithography (SLA) or DLP 3D printers without needing to make any hardware modifications, Ge said in a press statement.
Researchers published a paper on their report in the journal Advanced Materials Technologies.
To demonstrate the usefulness of their process, the team devised a soft robot as a proof-of-concept—a debris remover comprised of a continuum manipulator and a 3D-printed miniature soft pneumatic gripper, they said. The robot can navigate through a confined space as well as collect small objects in places that humans might have a difficult time reaching, researchers said.
