[whats-in-a-sentence]

For example, a transverse incision dividing the SAM from the primordium initial (I) caused the initial to develop radially without forming any adaxial tissue (Figure 19.3A). (...) However, two marginal incisions that allowed unimpeded communication between the SAM and the primordium initial led to the development of normal adaxial-abaxial symmetry (Figure 19.3B). (...) As described above, the abaxialized primordia produced by surgically isolating primordia from the apical meristem fail to form leaf blades (see Figure 19.3).

Miraculous Fairy Trees

Fairy trees are very common flora in Fairy Realm, but only two Miraculous Fairy Trees exist, under the protection of each of the two original main courts: Seelie and Unseelie, hence their titles. These Miraculous Fairy Trees gave life to twelve Kwamis each. Regular fairy trees are also capable of nurturing life, but those beings are referred to as Pixies, creatures far less powerful on their own without a holder to carry them.

Seelie Tree

The fairy tree housing the twelve Seelie Kwamis, guarded by Oberon. Though sadly over the years Oberon lost track of a few of them, they all seem to be getting drawn back to Sen City through various means...

"Qual o efeito da fumaça e da fuligem na taxa de fotossíntese, respiração e transpiração das plantas? Estudo publicado na Geophysical Research Letters comprovou que, quando o ar está cheio de fuligem de incêndios florestais, há uma diminuição significativa na troca gasosa entre as folhas e atmosfera.

As plantas realizam a troca de gases por meio de estruturas chamadas estômatos, pequenos poros presentes em abundância na face inferior (abaxial) das folhas. Essas estruturas são essenciais para a fotossíntese, respiração e transpiração, regulando a entrada e saída de gases e vapor de água, o que é vital para a sobrevivência e funcionamento das plantas. Muito semelhantes a bocas, os estômatos possuem células que formam uma espécie de lábio ao redor de um poro central. Esses “lábios” são chamados de células-guarda, que se abrem e fecham. Quando abertos, o poro interior chamado ostíolo permite a troca gasosa. Na fotossíntese, os estômatos permitem a entrada de CO₂ e a liberação de O₂. Na respiração, ocorre o inverso: liberam CO₂ e absorvem O₂. Já na transpiração, permitem que a planta libere água em forma de vapor.

O estudo revelou que, durante a exposição à fumaça, as plantas fecham os estômatos, ou seja, “prendem” o ar. Para agravar a situação, fumaças viajam longas distâncias. Com a interação com outros gases atmosféricos, a síntese dessa interação gera gases que podem degradar a superfície das folhas e oxidar o tecido vegetal.

Veterinary Diagnostics Market Size, Share, Growth & Forecast (2021-2027)

The Global Veterinary Diagnostics Market is projected to reach a valuation of US$ 6.14 billion by 2027, expanding at a robust CAGR of 9.4% from its 2020 value of US$ 3.25 billion. Veterinary diagnostics involve screening for underlying diseases in healthy animals and aiding veterinarians in monitoring disease progression or treatment response.

Several factors are propelling the growth of the Global veterinary diagnostics market, notably the increasing global pet population. In 2021, there were over 900 million dogs and approximately 600 million cats worldwide, with these numbers continually rising. The trend of pet adoption is driven by rapid urbanization and the shift toward nuclear families. The United Nations projects that by 2050, 68% of the world’s population will live in urban areas, up from 55% in 2018.

The rise in per capita income, leading to higher disposable income and improved living standards, is another key factor driving market growth. Increased spending on pet health, combined with rising disposable incomes, further boosts the market. For example, India's per capita income increased from Rs 72,805 in FY15 to Rs 94,954 in FY19, marking a 30% rise over six years.

Additionally, the growing demand for animal-derived food and the rising incidence of zoonoses worldwide are significant contributors to market growth. In India, 816 out of 1407 human pathogens are zoonotic. Major zoonotic diseases include rabies, brucellosis, Japanese Encephalitis, plague, leptospirosis, Scrub typhus, Nipah, trypanosomiasis, Kyasanur forest disease, and Crimean-Congo hemorrhagic fever. In 2018, India reported 110 cases of rabies, 1674 cases of JE, and 14971 cases of H1N1. Regular monitoring and testing of animals are essential to prevent these diseases, thereby augmenting the veterinary diagnostics market.

How to pronounce Abaxial in Portuguese

[leedsomics]

Spatial transcriptomics reveals distinct lineage identities for major and minor vein initiation during maize leaf development

Leaves of flowering plants are characterised by diverse venation patterns. Patterning begins with the selection of vein-forming procambial initial cells from within the ground meristem of a developing leaf, a process which is considered to be auxin-dependent, and continues until veins are anatomically differentiated with functional xylem and phloem. At present, the mechanisms responsible for leaf venation patterning are primarily characterized in the model eudicot Arabidopsis thaliana which displays a reticulate venation network. However, evidence suggests that vein development may proceed via a different mechanism in monocot leaves where venation patterning is parallel. Here, we employed spatial transcriptomics to analyse the spatiotemporal localisation of a subset of auxin related genes and candidate regulators of vein patterning in maize leaves. We show how different combinations of auxin influx and efflux transporters are recruited during leaf and vein specification, and how major and minor vein ranks develop with distinct identities. The localisation of the procambial marker PIN1a and the spatial arrangement of procambial initial cells that give rise to major and minor vein ranks further suggests that vein spacing is pre-patterned across the medio-lateral leaf axis prior to accumulation of the PIN1a auxin transporter. In contrast, patterning in the adaxial-abaxial axis occurs progressively, with markers of xylem and phloem gradually becoming polarised as differentiation proceeds. Collectively our data suggest that both lineage- and position-based mechanisms underpin vein patterning in maize leaves. http://dlvr.it/T2Mf3z
