Climate change is a defining challenge of the 21st century, and this decade critical time for action to mitigate worst effects on human populations ecosystems. Plant science can play an important role in developing crops with enhanced resilience harsh conditions (e.g. heat, drought, salt stress, flooding, disease outbreaks) engineering efficient carbon-capturing carbon-sequestering plants. Here, we present examples research being conducted these areas discuss challenges open questions as...

In this article, we describe the development of plant immunity field, starting with efforts to understand genetic basis for disease resistance, which ∼30 y ago led discovery diverse classes immune receptors that recognize and respond infectious microbes. We focus on knowledge gained from studies rice XA21 receptor recognizes RaxX (required activation mediated X), a sulfated microbial peptide secreted by gram-negative bacterium

In Arabidopsis roots, growth initiation and cessation are organized into distinct zones. How regulatory mechanisms integrated to coordinate these processes maintain proper progression over time is not well understood. Here, we demonstrate that the peptide hormone PLANT PEPTIDE CONTAINING SULFATED TYROSINE 1 (PSY1) promotes root by controlling cell elongation. Higher levels of PSY1 lead longer differentiated cells with a shootward displacement characteristics common mature cells. activates...

Abstract Rice paddies contribute substantially to atmospheric methane (CH 4 ) and these emissions are expected increase as the need feed human population grows. Here, we show that two independent rice genotypes overexpressing genes for PLANT PEPTIDES CONTAINING SULFATED TYROSINE ( PSY reduced cumulative CH by 38% (PSY1) 58% (PSY2) over growth period compared with controls. Genome-resolved metatranscriptomic data from rhizosphere soils reveal lower ratios of gene activities production versus...

The proposed lesson, a model active-learning activity designed to give college students experience in synthesizing information and developing solution, can be used address socioscientific issues across fields. As consequence of climate change, global temperatures are anticipated rise. This rise temperature is expected have negative impact on agricultural systems due part increased disease incidence decrease crop yields. written the context plant pathology emphasize importance collaboration...
