Unveiling common molecular mechanisms of parasitism and grafting — ScienceDaily

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena. Targeting this enzyme may help control plant parasitism in crops. Also, this mechanism can be exploited for novel cross-species grafting techniques to realize the goal of sustainable agricultural technologies.

Plant parasitism is a phenomenon by which the parasite plant latches onto and absorbs water and nutrients from a second host plant, with the help of a specialized organ called the “haustorium.” Once the haustorium forms, specific enzymes then help in forming a connection between the tissues of the parasite and host plants, known as a “xylem bridge,” which facilitates the transport of water and nutrients from the host to the parasite.

A similar mechanism is involved in the process

Concorde Replacement Edges Closer With Boom’s XB-1 Unveiling

Boom Supersonic has taken a big step toward putting a Concorde-like supersonic passenger plane into commercial service with the unveiling of a prototype.

Colorado-based Boom pulled the wraps off the sleek-looking aircraft at a special event at Centennial Airport in Denver on Wednesday, October 7.

Officially known as the XB-1 but nicknamed the Baby Boom, the jet is 21.6 meters long with a 6.4-meter wingspan, making it a third of the size of the planned Overture aircraft that the company is planning to build.

Featuring a carbon-composite airframe and powered by three General Electric-designed J85-15 engines, the XB-1 is expected to take its first flight in 2021 in tests that will help Boom refine the design of Overture.

The XB-1 only has space for the pilot, but Overture will seat up to 75 passengers while flying at speeds of Mach-2.2 — almost 1,700 mph, or more than twice the speed

IT Giant TCS Surges to Record After Unveiling $2 Billion Buyback

(Bloomberg) —

Tata Consultancy Services Ltd. surged to a record high after the Indian giant announced a share buyback of as much as 160 billion rupees ($2.2 billion) and said technology spending was recovering faster than anticipated.

Asia’s largest software outsourcing provider reported a larger-than-expected 7% fall in net income to 74.7 billion rupees in the September quarter. But Chief Executive Officer Rajesh Gopinathan said IT budgets were bouncing back and growth should accelerate as clients spend on digital services such as cloud migration, security and work tools to trim costs and adjust to a post-pandemic environment.

Amazon will hold its annual Devices & Services unveiling on Thursday morning, a virtual version of a fall tradition in which the company typically shows its newest Echo speakers and other Alexa-enabled devices.

The event begins at 10 a.m. Pacific time, and we’ll be updating this post with news and analysis as it unfolds.

If the recent pattern continues, the lineup at the event this year will reflect the tech giant’s efforts to expand the reach of its virtual assistant and smart speakers beyond the home. Alexa-enabled devices introduced at this event last year included a smart ring, eyeglasses and wireless earbuds.

In advance of the event, an FCC filing surfaced for what appears to be an Amazon game controller, as
