Among the oil-seed crops, Sesamum indicum L. is an important nutritionally rich crop, well adapted to grow in semi-arid regions. Waterlogging stress adversely affects growth of sesame by limiting diffused oxygen availability soil and generating hypoxic, subsequently anoxic conditions. The present study aimed screen 1,006 accessions for waterlogging response at seedling stage identify most tolerant susceptible genotype. investigation revealed that, 48 h are detrimental 10 days post-waterlogging impede crop survival. screened were narrowed down 8 detect morphological alterations, characteristics such as shoot height, root length, SPAD, branches per plant relative water content found maximum PB-Til 2 accession EC377024.

Climate-soil interactions improve the stability of grassland ecosystem by driving alpine plant diversity

Ecological Indicators, Journal Year: 2022, Volume and Issue: 141, P. 109002 - 109002

Published: June 29, 2022

The grassland ecosystem plays an important role in maintaining ecological security. This study intends to better understand the effects of climate-soil interaction on alpine and further deepen understanding plant diversity its influencing factors meadow, steppe, desert steppe Qilian Mountains China. Therefore, soil nutrient contents such as organic carbon, nitrogen, available phosphorus, ammonium nitrate-nitrogen were measured from uppermost 0–40 cm layer. In addition, regional vegetation characteristics also investigated index values determined. three types showed obvious variations content values. Alpine meadow highest nutrients, evident by greater carbon nitrogen compared steppe. With increase precipitation amounts, height number typical plants increased, but no significant impact elevation was found. Plant positively correlated with annual which primary determining Mountains. Compared other types, meadows most complex network, indicating greatest stability strong resistance environmental changes. These findings revealed a close link between species diversity, major climatic Mountains, are critical for predicting context climate change.

Climate factors drive plant distributions at higher taxonomic scales and larger spatial scales

Frontiers in Ecology and Evolution, Journal Year: 2024, Volume and Issue: 11

Published: Jan. 11, 2024

Introduction Understanding the environmental effects shaping plant distributions is crucial for predicting future ecosystems under climate change. The of different factors may vary in their importance determining at spatial and taxonomic scales, which affects our understanding plant–environment relationships. However, this has not yet been systematically explored. Methods Here we combined global distribution data 205 widely distributed families from multiple databases. We then used random forest algorithm to quantify relative (including climate, soil, topography) on plants three levels (family, genus, species) scales (10 extents 1° × 10° randomly located across globe). Mixed-effect models were assess significance globe. Results found that had increasing higher larger (yet stochastic finer than 4° 4°). Edaphic congruously decreased as increased. Topographic a relatively influence (i.e., family>genus>species), but with slow rise increase scale. Discussions Our findings are generally aligned current knowledge have also indicated potential complexity underlying scale-dependence distributions. Overall, highlight multi-scale insight into ecological patterns mechanistic processes.

Abstract Aim Historically, climate has been a dominant driver of global vegetation patterns. Recently, ecological understanding updated to acknowledge the influence human land use (the biodiversity change) in shaping We test whether Raunkiær's life form, plant classification system designed reflect climatic drivers, affects how plants respond both and climate. Location Forty‐one countries across six continents. Time period 1990 2013. Major taxa studied Terrestrial plants. Methods Combining data from database PREDICTS, trait databases TRY BIEN, we generalized linear mixed models with weighted effects coding form response over 4800 species at 300 sites globally. Results provide evidence that is comparable influencing occurrence produces divergent outcomes forms. Main conclusions Combined suitability, acts as filter contracting realized niche trees expanding disturbance‐tolerant species. Our results highlight fundamental role activity species' distribution.

How many animal‐pollinated angiosperms are nectar‐producing?

New Phytologist, Journal Year: 2024, Volume and Issue: 243(5), P. 2008 - 2020

Published: July 2, 2024

Summary The diversity of plant–pollinator interactions is grounded in floral resources, with nectar considered one the main rewards plants produce for pollinators. However, a global evaluation number animal‐pollinated nectar‐producing angiosperms and their distribution world‐wide remains elusive. We compiled thorough database encompassing 7621 plant species from 322 families to estimate proportion reliant on animal pollination. Through extensive sampling communities, we also explored interplay between production, resource diversity, latitudinal elevational gradients, contemporary climate, environmental characteristics. Roughly 223 308 are nectar‐producing, accounting 74.4% biotic‐pollinated species. Global patterns reveal distinct trend along altitudinal increased proportions producing high latitudes altitudes. Conversely, tropical communities warm moist climates exhibit greater lower plants. These findings suggest that ecological trends driven by climate have fostered diversification resources warmer less seasonal climates, reducing solely Our study provides baseline understanding relationships, diversification, traits.
