​A sequence change in a single protein allowed a tomato virus to become a global crop pandemic​​

By | Agriculture, Fruits and Vegetables, News, Plant Health

disease has emerged, threatening tomato production worldwide. This is caused by the Tomato brown rugose fruit virus (ToBRFV), a member of a devastating group of plant viruses called tobamoviruses. ToBRFV overcomes all known tobamovirus resistance in tomato, including the one conferred by Tm-22, a resistance gene responsible for the stable resistance to these viruses for more than 60 years.

How bread wheat got its gluten: Tracing the impact of a long-lost relative on modern bread wheat

By | Agriculture, News, Plant Science

Genetic detective work has uncovered an obscure ancestor of modern bread wheat, in a finding similar to uncovering a famous long-lost relative through DNA analysis in humans. Researchers have sequenced the DNA from 242 unique accessions of Aegilops tauschii gathered over decades from across its native range – from Turkey to Central Asia.

Why roots don’t grow in the shade

By | News, Plant Science

Plants need sunlight to survive. Researchers have discovered that when plants are grown in the shade, they turn on hundreds of stress-related genes. The researchers found that a specific group of proteins called WRKYs are responsible for stunting root growth so the plant can focus on growing taller. They hope that their findings will help other researchers design plants that can still thrive without sunlight, which may help farmers grow more crops in denser fields.

The introduction of perennial plants among rainfed almond trees helps to mitigate climate change

By | Agriculture, News

The potential of intercropping with perennial plants in woody systems to mitigate climate change through soil carbon sequestration could increase in the long term, once the new crops are fully developed and stabilised. The ongoing nature of the research would enable to confirm if this type of diversification would be a long-term solution to convert these systems into carbon sinks, thereby contributing to mitigating climate change.

Fleshy Fruits Are More Common in Tropics: Phylogenic Analysis

By | Fruits and Vegetables, News, Plant Science

Fruits can be dichotomously classified as fleshy or dry. Although many factors have been proposed to explain the pattern that the fleshy-fruited species occur with deceasing latitude and altitude, the relative importance of these factors has not yet been resolved. Researchers have investigated in a recent study factors affecting fruit type (fleshy vs. dry): plant growth form, environmental constraints (summarized by climate region), and phylogenetic conservatism.
