plant : any of a kingdom (Plantae) of multicellular eukaryotic mostly photosynthetic organisms typically lacking locomotive movement or obvious nervous or sensory organs and possessing cellulose cell walls — Webster
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is today generally limited to the green plants, which form an unranked clade Viridiplantae (Latin for “green plants”). This includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae, and excludes the red and brown algae. Historically, plants formed one of two kingdoms covering all living things that were not animals, and both algae and fungi were treated as plants; however all current definitions of “plant” exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria).
Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although asexual reproduction is also common. — Wikipedia
Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including ca 369,000 species of flowering plants), and ca 20,000 are bryophytes. — Wikipedia

Botanical garden is a garden dedicated to the collection, cultivation and display of a wide range of plants labelled with their botanical names. It may contain specialist plant collections such as cacti and other succulent plants, herb gardens, plants from particular parts of the world, and so on; there may be greenhouses, shadehouses, again with special collections such as tropical plants, alpine plants, or other exotic plants. Visitor services at a botanical garden might include tours, educational displays, art exhibitions, book rooms, open-air theatrical and musical performances, and other entertainment.
Botanical gardens are often run by universities or other scientific research organizations, and often have associated herbaria and research programmes in plant taxonomy or some other aspect of botanical science. In principle, their role is to maintain documented collections of living plants for the purposes of scientific research, conservation, display, and education, although this will depend on the resources available and the special interests pursued at each particular garden. — Wikipedia

This study shows that the ARR17 gene functions as a sex switch, triggering female development when on and male development when off. This single-gene system enables dynamic evolution of poplar sex chromosomes.

Nature Plants, Published online: 01 June 2020; doi:10.1038/s41477-020-0679-2Plants need to respond swiftly against attacks, but when pathogen pressure is weak, defence genes must be repressed as they impede development and growth. Three RNA helicases are now found to control decapping-dependant mRNA decay and negatively regulate plant immunity.

New biosensor visualizes stress in living plant...
on June 1, 2020 at 7:21 pm
Plant biologists have developed a new nanosensor that monitors foundational mechanisms related to stress and drought. The new biosensor allows researchers to analyze changes in real time as they happen involving kinases, enzymes that catalyze key biological activities in proteins. Certain kinases are essential since they are known to be activated in response to drought conditions, triggering the protective closure of small pores on leaf surfaces known as stoma.

on June 1, 2020 at 3:33 pm
New research suggests dry air combined with warmer temperatures may prompt bigger than expected changes in how water moves through plants. The adjustment may allow plants to survive with less water in future droughts, while downshifting how much carbon they absorb.
A hormone -- plant style
on May 29, 2020 at 7:06 pm
Researchers have now found a method that might make the production of a biologically significant precursor of jasmonic acid more efficient and cheaper. Their innovation: they imitate how plants produce the hormone. The result is 12-OPDA, a central precursor of jasmonic acid. In the long term, it could also be a potential precursor for high-quality perfume.

The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants. Research teams have now not only exchanged single genes, but recombined entire chromosomes with the CRISPR/Cas technology. In this way, desired properties can be combined in crops.

Contaminated soils determine root characteristics
on May 29, 2020 at 4:02 pm
Tree roots have multiple essential functions for their growth and survival. Acquiring nutrients and water from the soil, storing food and anchoring the plant in a substratum are what keep plants alive. In addition, root traits adapt themselves to physical limitation: they grow longer and thinner in dry soils in order to seek faraway water and they stay shorter in compact soils. Thanks to these powers, roots are an important pillar in tree survival strategy.
