Green plants (Viridiplantae) include around 450,000-500,000 species1,2 of great diversity and have important roles in terrestrial aquatic ecosystems. Here, as part the One Thousand Plant Transcriptomes Initiative, we sequenced vegetative transcriptomes 1,124 species that span a broad sense (Archaeplastida), including green (Viridiplantae), glaucophytes (Glaucophyta) red algae (Rhodophyta). Our analysis provides robust phylogenomic framework for examining evolution plants. Most inferred...
Summary Much of humanity relies on rice ( Oryza sativa ) as a food source, but cultivation is water intensive and the crop vulnerable to drought high temperatures. Under climate change, periods reduced availability temperature are expected become more frequent, leading detrimental effects yields. We engineered high‐yielding cultivar ‘ IR 64’ produce fewer stomata by manipulating level developmental signal. overexpressed epidermal patterning factor Os EPF 1 , creating plants with...
An integral part of global environment change is an increase in the atmospheric concentration CO2 ([CO2]) [1Long S.P. Ainsworth E.A. Rogers A. Ort D.R. Rising carbon dioxide: plants FACE future.Annu. Rev. Plant Biol. 2004; 55: 591-628Crossref PubMed Scopus (1316) Google Scholar]. Increased [CO2] reduces leaf stomatal apertures and density stomata that plays out as reductions evapotranspiration [2Mansfield T.A. Hetherington A.M. Atkinson C.J. Some current aspects physiology.Annu. Physiol....
Abstract Stomata are adjustable pores in the aerial epidermis of plants. The role stomata is usually described terms trade-off between CO 2 uptake and water loss. Little consideration has been given to their interaction with below-ground development or diffusion other gases. We overexpressed rice EPIDERMAL PATTERNING FACTOR1 ( OsEPF1 ) produce plants reduced stomatal densities, resulting lowered leaf conductance enhanced use efficiency. Surprisingly, we found that root cortical aerenchyma...
ABSTRACT The phytohormone jasmonate (JA) coordinates stress and growth responses to increase plant survival in unfavorable environments. Although JA can enhance UV‐B tolerance, the mechanisms underlying interaction of this response remain unknown. In study, we demonstrate that UV RESISTANCE LOCUS 8 ‐ TEOSINTE BRANCHED1, Cycloidea PCF 4 LIPOXYGENASE2 (UVR8‐TCP4‐LOX2) module regulates tolerance dependent on signaling pathway Arabidopsis thaliana . We show nucleus‐localized UVR8 physically...
The patterning of stomata plays a vital role in plant development and has emerged as paradigm for the peptide signals spatial control cellular differentiation. Research Arabidopsis identified series Epidermal Patterning Factors (EPFs) which interact with an array membrane-localised receptors associated proteins (encoded by ERECTA TMM genes) to stomatal density distribution. However, although it is well established that arose very early evolution land plants, until now been unclear whether...
Summary The considerable drought tolerance of wild cereal crop progenitors has diminished during domestication in the pursuit higher productivity. Regaining this trait crops is essential for global food security but requires novel genetic insight. Here, we assessed molecular evidence natural variation barley ( Hordeum spontaneum ), emmer wheat Triticum dicoccoides and Brachypodium species collected from dry moist habitats at Evolution Canyon, Israel (ECI). We report that prevailing vs...
Abstract Determining the harvest location of timber is crucial to enforcing international regulations designed protect natural resources and tackle illegal logging associated trade in forest products. Stable isotope ratio analysis (SIRA) can be used verify claims by matching levels naturally occurring stable isotopes within wood tissue location‐specific ratios predicted from reference data (“isoscapes”). However, overly simple models for predicting isoscapes have so far limited confidence...
Seed germination is highly temperature sensitive. Climate change factors such as increasing temperatures are likely to have a harmful effect on agriculture, particularly after crop sowing. Better utilisation of indigenous, arid–resilient crops like fonio (Digitaria exilis) commonly proposed solution improving food security. This study develops knowledge requirements and how these correspond future climate conditions across West Africa. We use combined approach; integrating seed experiments...
Bryophytes, the most basal of extant land plants, diverged at least 450 million years ago. A major feature these plants is biphasic alternation generations between a dominant haploid gametophyte and minor diploid sporophyte phase. These dramatic differences in form function occur constant genetic background, raising question whether switch from gametophyte-to-sporophyte development reflects changes spectrum genes being expressed or alternatively only limited gene expression plant are due to...
Summary The early evolution of plants required the acquisition a number key adaptations to overcome physiological difficulties associated with survival on land. One these was tough sporopollenin wall that enclosed reproductive propagules and provided protection from desiccation UV ‐ B radiation. All land possess such walled spores (or their derived homologue, pollen). We took reverse genetics approach, consisting knock‐out complementation experiments test functional conservation...
Drought, or environmental water deficit, is one of the major limiting factors affecting crop yield worldwide. Development drought-resistant cultivars a research and development challenge. Drought-related experiments are performed usually to understand physiological molecular mechanisms drought tolerance. Such also develop transgenics resistant using markers. executed in growth chambers, rooms, greenhouses, wire net-houses fields. However, plethora publications investigating has experimental...
